I wonder how they could get those pump gas numbers which are MUCH higher than the VF30 pump numbers (mods do differ some). Perhaps they are taking advantage of the bigger exhaust housing somehow. I knew the VF23 would come through.

Care to comment Phil?

Holy crap! On pump gas!

Cant wait to see what a FMIC does for a VF30

I would tend to think it has to do with the FMIC.


Actually, it is because of TXS' new secret weapon--nmyeti

bill, here is a napkin. You have something on your nose :rolleyes: :p

Seriously, if you look at the other post, the VF23 'feels' faster and makes good number as well (not to mention has a bigger turbine section).

Hey guys, this is being posted for one of our customers, Jay, who can't post the dyno plot himself.

I'll let the chart speak for itself!

http://www.turboxs.com/images/jay%20335%20hp%20on%20pump.jpg

I can't say this was an easy tune as Jay had quite the assortment of parts. Here’s the list: VF23, STI inj, MRT FRT MT Intercooler, HKS Headers, Blitz BCtrl, Stromung catless TB, some radiator, and of course a custom tuned TurboXS Unichip.

We could have kept going but we were hitting the fuel cut in our harness and felt this was the right amount of power. This was by no means tuned to the edge and was actually richer than most available kits.

Jay picked a great combination of parts that just worked well together. I would have to say the MVPs are the radiator and the front mt intercooler.

Who needs a unichip anyway?;)

Can you say 11 sec timeslips on pump gas.

I do, just someone else is living in them for now. My house is not ready for me till July 1st.

My wife gets into town on the 8th. At that point, i'll move out of Mark's spare room and take up some temp housing for a few weeks with my wife.

In any case its good to be here. Phil was awesome on the dyno today! He worked like a madman and the results speak for themselves.

-Nathan

those are really nice numbers...i wish i had the option of taking the motor out of my car for a few days to install all the goodies on it!

VF23 Making that much power?! Hmmm....

You should travel the country with that thing and give free rides to anyone with a Subaru...... :)

Can't wait to see a timeslip!

Who needs a unichip anyway? ;)


YOW....NOW THATS A ZINGER!!! :D

Who needs a unichip anyway? ;)

:lol:


Bill

i'm afraid to ask.. but what was the boost on that run?

Congrats great numbers....

what boost and what intake?


Nick

The radiator in the car is the C&R racing radiator. The boost was set a little over 20 psi. You can view some of the pictures from the install on our NEWS page at www.teaguesauto.com

The results are all from a combination of things starting with the best parts and a install done right. We did not cut corners and it took a little longer than we wanted but most of the wait was for the parts.

We have more customer cars like this on the way so keep checking back to the web site.

I will be posting a list of the mods done to the car as well. All of the parts can be found on our web site.

Can't wait to see the time slip from the track :)

WOW - a whole 4.5 hp more that my last run on the super AFC with stock plugs and misfire !!

Somehow I doubt that's a North American record. Maybe a North Carolina record. I just spoke to the owner of the WRX that will be gracing the cover of Turbo magazine for their August issue who makes 375hp to the wheels (his name is Earl; the owner, not the car). I recall the old adage "There's always someone faster".

Sick #'s and props to TEAGUES and TXS.... As always TXS comes through.

I knew it was only a mtter of time before Al Spit on this post.

You got beat deal with it...take it like a man, or just make up more of your usual "I don't care anyways, this is just a hobby...my crap don't stink" posts.

Way to go guys!

Good numbers guys...keep it up

As for earl's car...he is in a different league...sweet car though indeed, and you cannot find a nier guy than Earl! (his 375 was done jsut the other day too out in Cali).

Al - you're in a totally different league now....forged (lighter) internals, vastly different cams...you really cannot compare yourself anymore to these guys

adam
Z-1

The boost was set to about 20.5 psi and our fuel cut is at 21 psi. I know this will be the combo of the week and it obviously deserves to be.

I honestly think this car is going to take a really good driver to get it into the 11s even though it's making crazy power. It takes awhile for this combo to come on line and also takes a bit to fill that big intercooler between shifts. So all you hp hunters take note.

I honestly think the midrange could have been optimized with more time and tuning. The VF23 really came to life with the front mt intercooler as some have speculated it would.

As a warning, I also had a very candid discussion with the owner who was willing to take the risk of a blown head gasket and a broken tranny. He was ok with it and if you have intentions of making this kind of power you should too.;)

Al, grow up and congratulate the man as he has pioneered a new combination that works just like you have.

Russ, Pete, Mark, where's my intercooler?:lol:



Phil
TurboXS

Fantastic work guys! I guess I have to get off my lazy butt, install my Maxim Works Manifold and get down there again to see what I can pull. I really was only looking for 325 but I guess I'll have to raise my goal for the ever increasing upper limit.

I'm just playin around to get a rise out of you guys !

BTW - Phil's comments about the shift lag between gears with the fmic ring a bell in my ears . . . I used to have the same problem - - - it was fixed with the gearing change of the sti box - just need higher ratios to get the shift points up higher in the power band !

PS - was that a stock vf23?? I notice a bigg differnce in the trq curve from the other vf23 dyno charts I saw

Phil,
great job today! I cant wait to start playing with our own cars a bit more
on the dyno. What do you think... will this HP record last for much more
than 2 weeks?

Everyone else...
Thanks for the kind words. I really feel like a kid in a candy store working
with these guys. I love what we are doing, and days like today, where we
send home a very happy customer, really bring that into focus.

This combo has a whole lot more left in the car. I would have not been
surprised if we could have seen another 15hp or so on pump gas. The car just
kept responding to the tuning, and there was no hint of detonation.
Everything looked great. I really wanted to play with this car and some C16
race gas.

This car has the power to be into the 11s. It pulls very hard on the street,
and the only thing that will hold it back would be the somewhat heavy wheel,
tire, and brake setup he is running on the car. I would love to see him swap
in some wheels and tires that are a bit lighter, as the set he has now are
about 10lbs a corner heavier than stock.

-Nathan
www.turboxs.com

The stock Vette only gets 300 HP to the wheels but the Z06 gets 350 - You are right there!! Can't wait to see some track times! My 2 cents - don't drop the clutch or your transmission may have problems. I suspect that if you had a VF30 or 34 you'd do slightly better.

Good Luck!

Awesome, Awesome Stuff.......Congrats to TurboXs...I would think High ll's...with the right driver...for sure...hope his tranny stays together.....

Bill

Very impressive numbers especially given on straight pump gas.

It will be very interesting to see how it runs both on the strip and as a daily driver.

Larry

Ditto the comments on the benefits of (a) lighter wheel/tire combinations, and (b) the tremendous impact that proper insightful tuning has in bringing it all together.

Looking forward to seeing WRX timeslips in the 11s!

As for me and my WRX, as it is my daily driver and weekend warrior, I'm happy with dependable 12s just fine.

But it sure is neat to hear information on where people are taking the WRX these days in performance.

Cheers, GoodFinder :)

Wonder if Earl is the same white WRX from the Jan. 2002 issue.....Subaru Invasion

From looking at the charts I see that the peak tq and hp numbers are almost at the same rpms. If the car has stock cams and heads I assume from the mods description it seems a little off from other dynos I've seen. Can somebody coment on this?

From What I know...Teagues took the engine out to get the headers on....The bottom end is stock....with stock cams...The engine was NOT opened up at all..the turbo is a STOCK Vf23 from MRT...using STi injectors....Samco Hoses were used thruout....including Radiator...the Radiator is a exceptional ...C&R makes very HIGH quality stuff....used in all forms of racing...
and of course the genius's at Turbo XS....I think it has a flywheel in it as well....not sure of the brand...JUN maybe???? not sure...or MRT....Thats about all I know about...I know the car is going to be a "show car"....and someone asked about the rims...Volks with Kuhmo's...Dale did an awesome job on the install to get it to quality it is....so some mad props to him....

Great job guys.

I may have to visit TurboXS myself soon!!

Why on earth did they pull the engine to put headers on?
Was the head gasket replaced? thanks later

Well - in order to change the headers on a WRX all you do is unbolt them from the bottom and they come stright down

I seriously doubt anyone would pull an engine to remove the headers

If you look at the trg and hp curve of this fv23 compared to all other vf23 dyno charts I have seen, you will see that there is something very drastically different on this dyno map from all the others

The vf23 maps dont spike up like that in one peak hp area

I can only speak about what I see - and seeing the engine on the ground and the dyno map that results . . . . .

Well if you see a cat in the kitchen and the milk container is knocked over and empty - - - who drank the milk??

I still would like to know how come the torque peak got moved from 3x K prm to almost 6 K? The horsepower peak stayed almost in the same rpm range. This almost looks like either the cams or head were modified or it look too much like a supercharged engine torgue graph( supercharged engines make hierst boost at highest rpms). Which means the turbo was spooling up very, very slowly and only come to full boost at high rpms.
Coments?

Alex...:confused:

Al,

We have never seen any of your recent dyno charts, so can you please post them so we can nit pick them to death. For all we know your lying about your hp numbers.

Would you feel better if his car had a built engine? I don't think it would make less hp if it did. It doesn't by the way.

You'll know soon enough what a built engine is capable of.

Al, why don't you come down to TurboXS and we'll let you run your car on our dyno. If you beat it without nitrous, the dyno time is free.

This way we can compare apples to apples. The only thing we'll have to do is reset the dyno to match your different gear ratios.

Let's settle this once and for all.

I suspect the very poor matching of the hks headers to the up-pipe (much smaller inlet than the outlet on the HKS headers) had something to do with this. This car was laggy, but pulled like a rocket up top.

Besides, how many of you have ever seen a dyno plot from a car with HKS headers?

-Nathan
www.turboxs.com

The last thing I want to do is to take sides on this or to slam anyone but I smell a rat on these dyno plots.

One thing is clear. You cant make 400+ hp out of a stock VF23 on a stock EJ20. To even suggest that is ubsurd. look at the plot of that turbo. I dont care what tuning was done.

To give TXS the benifit of the doubt they may have not known about the mods done to the turbo or engine. I hope that is the case with this recent tune job. I like the TXS guys and I think they have done alot of work towards making HP but this is just incredible.

Nathan, I am suprised that you are not making a Nice guy post saying what I said above... Do you honestly believe that this is ligit?

Something is not right. That turbo was modded, That engine was modded, the dyno is out of calibration or, worse yet. Someone is lying.

I hate to be the one that calls BS on this as I dont want to start a war against anyone but this is just out of line and it needs to be questioned.

Someone own up or I for one will have a low opion of TXS and the crew for supporting such nonesense. Sorry guys but its to the point that I can no longer believe the numbers you guys are posting. 365hp from a VF30 with its little exhaust housing was hard for me to swallow. But this takes the cake.

One more suggestion.. You guys have the tools and the talent. Why not make products and services with reliability in mind? Look around. The real big names in the tuning industry always build reliable products. Thats the key. If you are going to sell a turbo kit with X turbo why not sell that kit running the turbo in its design limits? Even if that means giving up 30hp? Using the excuse "this is what the customer wanted" is not a valid excuse.

Why not use the old formula. Build an insane WRX and use that to show what you can do. Race the car, Win with the car, Break records with the car. Then sell reliable strong and safe kits to the consumer.

Someone start talking.

Speaking of current top Subarus and the USCC, it's in the July issue of Sport Compact Car magazine where you'll find the 92 entries for us to choose from (and vote on) in the "Ultimate Street Car Challenge" contest.

The five Subaru entries are:

#80 - Steve Harvey (that's me, GoodFinder)
#81 - Jason Lochhead (gmflex on i-club)
#82 - Brett Gordon (Bighurt1 on i-club)
#83 - Alan Card (Scoobyslack1 on i-club)
#84 - Mike Morita (??? anybody know him on i-club ???)

(You have to clip the actual ballot out of the physical magazine, no photocopies or emails or online voting, mark your 10 votes, and then snail mail it in to Sport Compact Car magazine.)

To ensure Subaru representation and participation in the event, we gotta get the votes mailed in!

GoodFinder :)

Nice numbers. FMIC and headers sound like Stage 5 material.

I am laughing at all the "conspiracy" talk. You guys watch X-Files to much. Phil posted some nice dyno numbers when he ran well at the track, so that must mean TurboXS and the Drag strip are in cahoots. Maybe Phil is an Alien, the wicked 60' times he is cutting are proof, Where's Mullder and Scully.

Troy

/\....Soooooooooo true....Sheeeeeeeeesh...I honestly can't believe some of you are such doubting thoamas's....my god....What does it take....Maybe when that thing pulls up next to you and Blows the Bejesus out your "modded WRX"...you might think twice....

While in Australia...I had to the opportunity to talk to a BUNCH of WRX owners including some VERY high Profile tuners......The STD setup down there is....a VF23, Front Mount, Fuel Defender, 3in or 3.5 Turbo Back Exhaust's, uppipes and an intake...Try 345 HP at the crank..and run 18.5 psi ALL DAY long...on pump gas...For the Lucky individual's that want more...One of Toni Rigoli's cars was cranking out 350 to the wheels on a STOCK bottom end....So unless you have some other things that "Prove this wrong" in this guys car. Enjoy it...Some of you really need to get out more....others just need to realize the truth...

AZScoobie...to you my friend...you raise some good questions however they lack any substance for thought....I mean...there are at least 35 four wheel dyno's all over austrailia...Are you saying those are just as inaccurate??? I have a copy of Hot4's magazine that features nothing but Subaru's...they had a Dyno day...and most of those cars had Stock bottom ends and a few with some forged goodies...But most of them were in the 375-400hp range with just bolt-on's..and ECU modication...Most did not have headers as The WRX in question here had......There is actually one guy...(Mick Jones, President of the Queensland WRX Club, that can ran 345 to the wheels all day long with his VF23 and NO Bottom end work)..So I guess unless you have actually been there and seen it you probably wouldn't believe it...But he had Dyno Sheets to prove it too...You have to remember...The US is very much in its INFANT stage of tuning the WRX...Whereas Australia, UK , Japan and others have a 10 year head start...So if I were you, I would not jump to such 'conclusions'...and take the attitude of sit back and see...:D..



Scooby South

I understand people may be skeptical about the numbers but I just wanted to make it clear that it had nothing to do with the dyno. This was also not intended as a TXS advertisement and the only TXS part he had on his car was our Unichip kit.

I was honestly only shooting for 320whp. That radiator kept his coolant temps remarkably low to around 81-83C on the dyno where we would normally see 86-90C. Let's not forget that intercooler. As soon as we turned the dyno fan on, his ecu started to add large amounts of fuel to just idle. That is some serious cooling!

I can't say with absolute certainty that this car didn't contain any secrets but in dealing with Jay, I highly doubt he would hide anything. He was very proud of his ride and was only expecting around 320whp.

My car will be similarly equipped in the very near future but with a VF30 or 34, so all you guys hunting for 11sec timeslips better head to the track soon.;) I'll post the results if you want.

Have a great weekend.

I'm looking at my old dyno graphs and the torque correction factor (tcf) and the ratio are the same as they are in this graph. Doesn't that prove that there have been no adjustments to the dyno?

If it does than you guys are full of crap...

edit: I went way back to an old thread and found this chart (Nov 2001) again with the same tqf and ratio:

Somehow I seem to find ground to stand on our claims in several dyno runs, a stack of fast (mph) timeslips, and a whole load of happy customers. There are several things that you need to keep in mind about compressor maps. The most important one is that they don't seem to tell you everything. Take the 1820 for instance; it has a very nice compressor map, and the design of the compressor wheel seem to be very well suited to the WRX, but the turbo is let down on the turbine side.

The VF23, while not the best turbo I personally have seen, in this setup did a very good job. However, while the VF23 provided the air, the real hero here is the Hyperflow intercooler which provided so much cooling that fuel trims changed drastically the moment that the fan in front of the dyno was turned on. How efficient a turbo is at a given boost pressure matters much less if you can pair it with a very nice intercooler to remove a considerable amount of the extra heat the turbo creates from compressing the air.

In this case it is quite clear that a VF23 managed to make the HP that you claim it "can't" make. It's dyno numbers against speculation.

These results are very much credible. I am tired of bowing to the "subaru" gods that say it can't be done, because they have yet to accomplish it. These results are consistent with lots of different tuners in the Australian market. The majority of them just don't post here as they are too busy making HP. The previous fast-4s article that was mentioned really tells the tale. We are not the only tuner to get results such as this. In fact I would go far enough to say that these results are very much consistent with my findings in other turbo charged cars. The WRX is not that much different from a DSM, and people are doing things now with those motors that the "experts" claimed would never be done.

Clark, I am shocked, and even a little hacked off by your accusation. I have NO reason to lie about this kid's modifications, state of tune, or dyno results. This car was as advertised. The fact is the only TXS part that it had on it was the unichip. Phil had a good tune on the dyno, and the car really seemed to like the combo of modifications. To imply that I am lying to you, come on man think about that. Why would we risk what is very much considered to be one of the best, and most honest customer service reputations in the business.

You can have any opinion of us that you wish, but I would think that after all the time you've spent on the phone with Mark asking technical questions, and after all the PMs that you and I have exchanged trying to work out the problems that your car has had that you'd have a much better idea than most of how we really work.

I don't have to answer to you in that manner, and I don't have much more to say on this topic. We have given the I-club all the information on this car, its setup, and our tuning. There is nothing more to tell.

Thinking more and more about this - and after seeing so many dyno sheets on wrx - I really don't see how this was possible with street gas - in fact after many many dyno pulls under my belt on two different engines with a whole lot of diffrent turbos and mods - - I say that the stock WRX block and heads can NOT do 335 hp on street gas with a stock vf23 turbo

Now if they sent the turbo out to have some work - then and only then could I see that trq curve and the xtra top end kick that no other fv23 we have seen has ever made

Of course - I always stop pressing at the first sign of activity on the knock link and back off - I like to have some numbers to brag about - but don't want a blown engine to deal with

Well - I guess I just don't relaize the POWER of the radiator! (jokes)

Al,
I am going to say this as nice as i can, get your panties out of a wad. Your speculation is really about worthless in this thread. You didn't see the car, and you've never had the chance to see a car with this setup on the dyno. If your upset because you have no title left, well, i guess to each his own, but lets try to be mature. Your reasoning is flawed. Just because you can't make this sort of power, does not mean it can't be done. You've yet to tell us why it can't happen, only that you don't think it can happen.

all here who think Al knows everything about the WRX, say "I"

Didn't think you'd get too many votes.

i suspect there are 3 reasons why the turbo had such a weird torque curve.

1. The up-pipe was not port matched to the collector on the headers which created lag
2. the intercooler core volume was HUGE, and contributed to tons of lag
3. the intercooler has very little pressure drop across it and as such the turbo does not have to work as hard to keep the boost pressure up high on the top end.

If you combined this setup with some sort of anti-lag to get the turbo at full spool by the "normal peak torque" range, i think you'd see much higher peak numbers there, but as it was making very little boost at the normal 4000rpm range, it didn't happen.

This car was not tuned to the edge, although i suspect that he could use some larger fuel injectors, but it was not anywhere near detonation.

If you don't realize the benefits of a decent cooling system to pull heat from the head and combustion chamber of a car and the further impact that has on detonation then you may well be beyond help.

The radiator didn't make power, but it sure helped remove heat from the head, and as such likely allowed us to make more power on pump gas without detonation. How much more? I don't know.

www.turboxs.com - Well I came within 4.5 hp with lower boost and misfiring plugs - and not to mention a much more balanced power curve with a flat trq curve over 4100 so I wouldn't say that - - also my old engine was within 10 hp

I have almost the same mods so after I dyno tune it we can compare results. I actually called TXS a long time ago to see if they have a map for this type of setup but they didn't have anything at the time.

My mod list:
VF23, 550cc injectors, tec3, vishnu uppipe, cusco headers, APS FMIC (it's a smaller bar&plate design vs the MRT), turboback exhaust.

I really don't expect to get anywhere close to those power levels but I guess we'll see.

PS - a dyno pull don't do nothing to my coolant temp - lots of time for rest between runs !

I think the public needs to know something. The above statement is a total and complete lie on nathans part. I have never called Turboxs. I have never spoken to Mark on the phone or asked him for technical advice. Not a single time have I called them.. I have never spoken to Nathan on the phone either.. I do not have a single Turboxs part on my car and I have never had anyone from Turboxs help me in anyway and I have not asked for there help.

Not sure why this was made up??? Maybe you are confusing me with someone else??? Please explain this to me as this is false information.

First off. Nathan, you are positioning this as a slam.. Not me. I simply posted what I felt and I even explained that I was not trying to slam anyone. I also stated that I did not and still do not believe the HP numbers you guys are claiming out of these little turbos and stock motors and I was looking for an answer. The only thing you offer is that the car had an FMIC. How about the compressor map for teh VF23. What does it tell you? According to that map can that turbo produce over 400hp?

I just wanted some clarification on these numbers. In the end all I got was an attempt on TurboXs part to slam me. For TurboXs that is a bad business move if you ask me. Then again. Running VF turbo's at 22+ psi and calling that reliable is also. I will not continue to go round with you guys on this. No point. Its clear I am not going to get the answer I was looking for.

CT I'mn looking for answers also

Originally posted by alfriedesq

As am I. Its to bad people have to resort to low blows.

A couple of points.

Tubular headers, FMIC's, and after market up pipes will generally bring the power in later. Tubular headers, depending on the design, will, or may change the torque curve.

Most people will know my opinions of some of the quoted power figures seen on this board, so I won't go there again.

However, I'm not certain what the guy quoting that the AUS' guys getting 345bhp at the CRANK, from similar mod's has in helping the cause. Or the fact that the AUS' guys get an average of 94bhp losses through the drive train.

Someone pointed out that AUS', UK, etc', were several years ahead, and the UK dyno site was even posted. It would seem that most people choose to ignore the infomation, gained from hundreds of dyno runs.

I would like to see some fuelling info posted, relating to this car. Like the IDC/IPW %, at peak power/rpm, and maybe the voltage output from the AFM.

So, just what is the IPW at 5900rpm ?

Lastly, for those who consider the VF23 to be so good, why does the graph show power to 6000rpm, and then it just dies ? A turbo that can produce 400bhp, can certainly flow enough air to hold 20psi at 7000rpm.

I don't believe Turbo XS, or any of the other tuners are specifically trying to "con" the owners. I just don't think most of them know any better.

Happy.

Many of you are just unbelievable.

What would you like to see? An 11sec timeslip? Another dyno plot? Would you like to examine my VF30 or VF23 before we go to the drag strip and take it into the 11s?

Will this settle this once and for all?

We have a header, we have a vf30, we'll get an intercooler, and we might even get that radiator.

Would one of you like to perform the installation and inspect the parts?

Would like to pump the gas into the tank?

Would you rather we run 17psi vs. 21 psi and up the timing to 35 degrees instead of 28 degrees?

If we run in the 11s will you concede to the so called impossible?

What will it take to prove that this is possible?

We've given you a dyno plot and all you've given us is a bunch of theory.

This "bunch of theory" is PROVEN. It is based on the laws of physics.

Why don't you just answer the questions, both here, and on the APS turbo thread ?

Happy.

Some of you are really making even following threads like this a waste of time. Grow up. I think the moderators need to give some of the usual players (trolls) a I-club timeout before the next success story gets posted. This recent behavior is making some of the (other clubs) look pretty mature. The flacid saber rattling needs to stop.

And thumbs up to TurboXS for the tuning work and all the others involved.

I am assuming that the "CT" at the end of your messages stands for Clark Turner. If it does not, than I apologize for the mistaken identity.

If it does, however, I guess you simply do not recall calling me last fall several times to discuss your WRX and to order a Unichip from me. You did not get the Unichip however, because, IIRC, you decided to wait for a Link. I also recall that this is what I was recommending that you do from the beginning since you wanted something that you could tune yourself (which obviously can't be done with the Unichip).

Clark, I own TurboXS. Neither me, nor my employees will lie to our customers. Not only is it bad business, it's simply not the way I want to run my business.

You used to run an aftermarket performance company. Go back and re-read your posts and put yourself in my position. You started this by attacking the integrity of my company. We are not going to sit around and let you do that with impunity.

I stand by everything that we have posted here.

HOLY SHAZBOT!!! :eek: now that is a man i don't mind giving my money to! i don't post in here a lot because half the stuff that people post just turns into arguments, and this is a good example. you people need to get off your friggin high horse! just because a lot of you people dumped more money in yuor motor than this guy your flipping out. How many other people have the radiator and intercooler, and had it Dynoed?!? the car has only been out a little over a year in this country, these guys are finding more power in this car every day! just because the aussies and the japanese had these cars for a lot longer does not mean crap. our car can not compare to the other side of the world. look what the American tuning has done to Honduhs. so to all the non believers :monkey: :monkey: :monkey: there are other people that stood by the VF23 also and the same people gave the crap, hmm maybe a lot of people just hate that turbo :lol: now stop your damn whining and give credit where credit is due! by the way nice TUNING!!!!!!!!!!!!!!

Kirk

I have dealt with Mark for about a year now. I feel this is important to note for because I am a service oriented customer that means I buy from whom I trust and I am not price driven. I do not have the tech expertise that many of you have that have posted negative posts, but I do have a great sense of who does business the correct way and who blows smoke up your ass Rule # 1 under promise and over deliver. In every dealing I have had with Turboxs that has happened. If there has ever been a problem Turboxs has been there, so for those of you that find it nessasary to to defame a very good tuner with theroies and news articles you read while in the ****ter. Do all of us a favour and pm them or call them, but don't clog up this forum with your angry" I know more than you yet I don't own a car shop" bull****. Thanks Michael

Who killed JFK? Where's Hoffa? Is there really a bigfoot? How did Turboxs get that much hp out of that engine???

All this conspiricy theory talk is getting me sick. I don't even know why the Turboxs guys even bother to respond to this stuff. I don't know why anyone would think they would lie. They are always honest with customers with what will work best on our cars even if it means taking the risk of not making a sale.

Note to Turboxs: From your customers who have dealt with you guys first hand, no childish remarks or accusations will tarnish your image with us.

Look, it's all very well people posting their support of a tuning company, and telling us just what a good job they do, but, this doesn't change certain facts.

I have asked certain questions, not because I believe Turbo xs are lying about their dyno figures, but because their dyno figures don't make any "logical" sense.

There are certain things that remain the same, regardless of what "bolt on mod's" you make.

1) Engine capacity.
2) The approximate amount of fuel you need per 1 bhp. Although this will vary a little, but by a small %.

So, using the same equation I posted on the "APS turbo" thread,

121.7ci (1994cc) x 5900rpm x .5 x 85%ve div' 1728 = 176cfm (n/a)

x 2.38PR (20psi) = 419cfm.

419cfm is the maximum amount of air you can force into our engine at 20psi, based on a VE of 85%. 85% +/- 5% is the recognised peak VE of a turbo engine. This will vary over the RPM range, but sinse this equation is normally used for turbo sizing, it's conservative.

So now we have something to go on.

1) is it possible to get 400bhp from 420cfm (11.9 cubic meters pm, 29lbs pm)

2) Can the turbo, a VF23 in this case flow enough air for 400bhp, regarless.

Well we need roughly 1.4cfm per 1 bhp, so 400bhp needs roughly 560cfm (16 cubic meters pm, or 38.6lbs).

So how does this look on the VF23 flow map. Well to be honest, I don't have it, but, I do have the flow map for the bigger VF22.

And on this map ? Well, I can't tell you that either, because it's SO FAR OFF THE MAP, that it isn't even on the same page !!!!!

It would even be fair to allow up to 10% disparity, for VE, and fuelling, it's still way out.

So to all you guys who blindly believe everything you're told, be happy (no pun intended).

To the more intelligent among you, check out what I, and others are saying, and make your own minds up.

To Turbo XS: I don't doubt your honesty, however, if you disagree with any of the information I've posted, I'll be glad to listen to your arguement.

My comments are based on FACT, your comments are based on software, and dyno calibrations, notoriously inaccurate, all over the world.

Happy.

First off I am the one (Teague's Auto) who built the car not Turbo XS so if anyone has any build questions ask me.

Second we pulled the motor because the car was getting a Unorthodox Light weight flywheel and AP racing clutch. Now last I checked you either have to pull the motor or the tranny and since the motor was getting injectors, headers, up-pipe and inlet hose it just makes the install go faster on the motor stand. The motor has no cams no block work never pulled off the timing belt covers to look at the belt.

Third if the VF30 is such a good turbo why are my customers in Japan, Australia and the UK pulling it off for the VF23?

Fourth We used Shiv's up-pipe on the car because that was the only one I could get my hands on at the time and we had been waiting on parts long enough.

In the end it comes down to one thing. If you have the money and want the same numbers bring your car to me and I will do the same install I did on Jason's car and you can watch the whole install to make sure I don't lay my hands on the block, heads or cams. Then take your car to Turbo XS and have them dyno it.

This is just the first car like this we are building more so get ready to have more to talk about and if you have been tuning Subaru's for as long as we have since (1976) then you can give me a call and tell me how to do my job.

Dale Teague (Teague's Auto)

www.teaguesauto.com and www.boxer4racing.com For all your SUBARU needs.

Very nicely stated, and no one got assaulted. It's always nice to read technical stuff.

Honestly, **** like this is why I rarely post here anymore. Mark and his crew at TXS and Dale at Teagues are PILLARS of the Subaru (WRX) performance community. I've dealt with both of them and they both bent over BACKWARDS to help me get a turbo back exhuast shipped to me in a matter of HOURS for a race! I wound up with the TXS piece simply because Dale wasn't able to find the setup I wanted. It wasn't for lack of trying, however.

What we have here are bunch of SLOWER, BITTER people who simply want to challenge REALITY because they have nothing better to do. Sounds like some people need to spend more time under their car or behind the wheel than sitting behind a monitor talking ****.

Dale and Mark, keep up the good work. Although my WRX will soon be sold since I'm going back to DSM-land :) I will continue to highly recommend you both to anyone in the market for your offerings.

Dale,

Thanks, for posting and clearing things up. As for the VF30 vs the VF23, the better choice has to do with your ultimate goals and driving characteristics.

Sincerely,
Phil

Happy. I agree with this asssertion 100% !! The laws of physics can't be bent

As far as Mark at turboxs gpes - he is a very very honest and good person who can be trusted in every manner. I dealt with him before and he imprssed me in every regard - the same can be said for Phil - who is also tops

However - now that they have choosen to align themselves with Nathan - who from my every observation is a diffrent kind of person all together - just look at the clowns he used to hang with in NM before - those obnoxious idiots nickV and the other imbasicles - I say b irds of a fetaher flock together

Mark always was smart enough to stay above the fray here in these stupid debates

Nathan wants to jump right in an sling the BS - all the while trying to protray the nice guy facade

- look at nathans tactics - - sneaky - manipultaor - out smart them behind the back actions then he goes to the smile in thier face; try to look like a very nice guy kind of person

Although I respect Mark and Phil greatly - - and would trust them 100% - I feel nathan is capable of anything

This dyno claim they made speaks volumes to anyone who knows anything about subaru engines and the laws of physics

I say it again - it can NOT be done with a vf23 - pump gas and a stock heads and cams

. Yeah - = I'm a slower - biter- sure - -

I have the same HP output as this guy does - only my powerband is wide and broad and the car has little or no lag


I'll be back at the dyno later tonight or tommorrow to take away thier thunder

In the meantime - I say dont believe this hype - its not real

The powerband tells the whole story - its aint a stock engine & vf23!

Al since you and Happy are so good with physics and say that it is not possible with the stock block and VF23, give us good reasons why they would lie about it.

I really don't see what the big deal is. Teague's has equipped a very nice WRX, TXS tuned it, the thing is making crazy power!

Who care's about the details. They've given all the facts. I personally trust these guys more than anyone else.

I would say that most of the fastest WRXs around have a TXS unichip in them if not many other parts.

Not to mention bybyv8, phil, and nathan drive some of the fastest WRXs on the streets!

VF34 equipped and with Turbo XS parts!!!

Wow you guys are sick.....truly sick......and that is being nice. Al, why should anybody listen to you?? You are the one that ALWAYS started all of those stupid debates. So when people stand up to you they are the sneaky unreliable ones??? YOU ARE AN ASS AND ALWAYS WILL BE :monkey: You are a cry baby and you need to grow up.

Happy...........again why should we listen to you??? Usually you are a level headed person but now...........what have you done for the subie community?? You have helped but in the way that Turbo xs has?? No way. You guys are IDIOTS. Here is a company trying to make a living off of customer service and proven performance and you guys will come out here and actually say they are liars and try to hurt their business.

I have never, NEVER had respect for Al and now I have lost any I have had for Happy.

:monkey: :monkey: :monkey: :monkey:
I hope that many of you out there are smart enough to not listen to Al. I really can't believe that crap you posted above Al!! Really that was the lowest that you have gone. Just when you think you've seen it all from such a cry baby looser you surprise us again. Nathan has always been the cool headed one of the group.

Why again are you guys doubting Turbo XS??? They just did the dyno and tuning of the unichip. So why are you calling them on this???? Jealousy??? The two of you have made yourselves look much worse then the damage you might have thought you would do to turboxs.

I HOPE THAT ALL OF YOU ON HERE ARE SEEING WHAT IS GOING ON AND REMEMBER THIS ALWAYS!! :monkey:

I honestly don't know why Al hasn't been to i-club timeout yet. It's pretty obvious he can't play nice since about every thread he posts in descends into a flame war.

And since he seems to have all this money to throw away on not getting it right the first time, I'm not sure why he didn't buy and Audi, Mercedes, or BMW to butcher.

We all know the saying any idiot can go fast in a straight line.. well any idiot can throw a superior engine into a car and go faster too.

As for keeping this on topic.. nice results.. almost makes me wish I didn't just drop a small fortune for a set of volks.. almost :D

It's pretty sad that these kinds of milestones spawn such haters in our ranks. Instead of "Wow, that's great.", we offer "Liars! It can't be done".
My science background has naturally made me skeptical about all claims made here but I know that the only way to assure yourself of results is to gather the facts, review the experiment and try it yourself. This is what fuels progress. NOT name calling, flying BS flags right and left and general ill will toward each other.
Al, you've admittedly taken a different path which makes your results nearly impossible for us to compare our results to. I know on paper some of these recipes don't add up but the fact is, until you repeat the experiment, who are you to nay-say? Teague has given us their version of the mod list, they have no reason to lie to us and both TurboXS and Teague have excellent service track records. You're certainly entitled to your opinion, I just think the name calling is a bit over the top.

Don't say that!!! Then he will remind us all that he has had all of those cool cars.:rolleyes:

www.benzsport.com really classy people. If he had a benz and went there he would be kicked out in no time.

The fact that he is still here really gives I-club a bad name and gives all MY02 wrx owners a bad name. Please leave. :monkey: Or somebody here please escort him out of here. :mad:

I wish some of you would READ WHAT I'M SAYING.

I do NOT BELIEVE Turbo XS are lying, I believe they are RELYING on UNRELIABLE information.

I have also said that people SHOULD CHECK WHAT I'm saying, and make their own minds up.

Some of you guys are completely ignoring FUNDIMENTAL issues, and blindly choosing to believe a machine that relys on how the software is used, and how well the dyno is calibrated.

I am telling you that you need a certain amount of air, and fuel to produce a given power figure. I am also telling you that an engine can only consume a certain amount of air, based on it's capacity, boost, and rpm.

Forget the VF23 issue, in this case it's not relevant.

Our engine can consume a MAX of 420cfm at 5900rpm, based on 85% VE.

You need roughly 560cfm to produce 400bhp.

Turbo XS either do, or should know this. It is common tuning knowledge.

If the information, or equations I've openly POSTED are incorrect, then surely someone, if not Turbo XS, can correct me.

I have also asked Turbo XS for IPW information. So far they have totally inored my posts, and questions. They have neither agreed, or refuted the cfm equation, or infact anything I've said.

WHY ? I would think that they would be eager to qualify their results, and correct my errors !!!!

The worst thing that can happen to Turbo XS, is that they find their dyno "is" inaccurate, and they get it corrected. If this were to happen, and they post the information, IMO, this would only be good for their credibility, and maybe the other tuners would follow suit !!!!

That was a good response Happy. That did set you apart from what others are crying about. You made some good points. Let's wait and see what comes of those questions. :confused:

Very good points. :)

I worked the numbers, and I also get 424cfm at 6K rpms @20psi (calculator (http://velocity.websitegalaxy.com/cfm.html) )

Just agreeing with the numbers.

Phil, can you comment on what you said about the VF23 vs VF30. You've always said that the 30 is superior in every way, and it usually makes more power from what I've seen, but most people say it 'feels' faster.

I do not have a single Turboxs part on my car and I have never had anyone from Turboxs help me in anyway and I have not asked for there help.

Not sure why this was made up??? Maybe you are confusing me with someone else??? Please explain this to me as this is false information.


Clark,
I never said that you and I talked on the phone. I said that you've talked to mark on the phone.

At present, I have 3 pm's of a series in my inbox which I saved, that I would be happy to post if you like to confirm my story. Mark has 13 emails saved on his computer from you, funny thing is one of the references a conversation you and I had about wideband O2 tuning. Shame I have not saved all my PMs from you, just the most recent.

In any case we would be happy to search the phone records and find out the last few times that Clark Turner called the shop. We have 800 service, and very well could do it.

Further more you’re listed on mark's Unichip old back-order list which you could only get on with a phone call.

We will combine all the above referenced information into a word file and make it available if you continue to insist that you've never received any advice from us.

Bottom line: your saying I am posting a lie to these people, and as the defender of truth, justice and the American way you must intercede. I'll get back to you on the math of this situation, but let’s just say that plenty of 2.0L cars have made 400hp with only 20psi of boost.

Nathan,

I'm really not certain how to comment on this statement.

It shows that you should really leave anything technically related to engine tuning to others at Turbo XS.

As an old saying goes,

"Before engaging mouth (or fingers :lol: make sure the brain is in gear".

Happy.

Al,
I'm amazed you are still bitching about everything. Secondly, no sane or intelligent person would call any of the 'Albuquerque' crew imbeciles (look, I can spell). Oh yeah Al, are you even one of the 50 fastest in the US right now? Face it, you'll never be the fastest.

Ive ordered parts from TXS, and purchased parts straight from Nathan. I've received nothing but the best service from TXS, and I still see them to be a model for performance companies to strive to, further, blaming your poor communication skills on anyone that haves fact to prove otherwise is foolish, and reckless. As for Nathan, he has done nothing but help me out with his vast expertise, and the guy gets further respect because I've heard him say that he doesn't know something, rather than BS.

Keep up the good work Nathan,
-Matt

If it does, however, I guess you simply do not recall calling me last fall several times to discuss your WRX and to order a Unichip from me. You did not get the Unichip however, because, IIRC, you decided to wait for a Link. I also recall that this is what I was recommending that you do from the beginning since you wanted something that you could tune yourself (which obviously can't be done with the Unichip).

Clark, I own TurboXS. Neither me, nor my employees will lie to our customers. Not only is it bad business, it's simply not the way I want to run my business.

You used to run an aftermarket performance company. Go back and re-read your posts and put yourself in my position. You started this by attacking the integrity of my company. We are not going to sit around and let you do that with impunity.

I stand by everything that we have posted here.

Mark
TurboXS

You have me confused with someone else. I never ran a TurboXS unichip. I took one on trade from a guy but sold it on i_club right away. I do not run a Link either. I did have a link at one point but sold it off due to the problems it had.

The only contact I have ever had with you Mark is through a local guy that ran a turboxs unichip. His car could not even get into the 13's with stage 1. I suggested he pull the unichip out and bingo 13.6. He talked to you several times about the map and I offered to datalog his car as per your suggestion. I burned the map of the Super Rich AF and the low advance numbers and put it on CD. He was going to send it to you. I think he gave up as he sold the unichip off the next week.

One thing is clear.. I have never called you Mark and I have never spoken with you. You are thinking of someone else or you are just making this up in an attempt to make me look bad. I advise you to stop now as its getting to the point of slander on your part.

I was not attacking your company or you Mark. I was looking for answers as I believe the Hp numbers you are claiming are to high. That my opinion. I gave you guys an oportunity to change that and all I got was slander. I see that others are asking questions as well and those questions are not being answered. That speaks volumes.

Now leave me out of this. Its clear to me exactly what type of business you run and I will never do business with you or your company. I will not continue to go round with you and your aqusations.

I guess we will have to agree to disagree... Leave it at that


CT

Is it me, or do some of these guys need grammar and spelling lessons?

How can a VF23 flow enough air to make 335whp when it could barely flow the air need to make that HP at the Flywheel.

Answer, You mod the turbo and do, or you dont.

Nathan, Your funy bro. You who have talked bad about VF series turbos from the begining. Are now saying these turbos can do things you have conceeded they could not. What happened to your Garrett project? Tell us again why you started down that route. And simply stating that you have seen 2l motors making 400hp at 20psi is meaningless without saying what turbo now isnt it. What turbo was that pray tell? I hope it wasent a larger turbo because if if was then you've just made yourself look stupid now havent you.

Al is an arrogant a-s-s no doubt. But facts is facts guys. Dont let your dislike for him cloud your senses.

Nathan. This is a waste of my time. I have a call into you and a call into Mark. Both of you now have my cell number. I want to talk to both of you on the phone. I have never spoken with Mark in my life. I have PM'd you back when you did not work for Turboxs looking for some help. I confused you with someone else I guess. I have sent email to Phil and Mark in the past but to be honest neither of them returned my email as far as I can remember. Go ahead and waste time by pulling phone records. The only one you will see is the call I made to both of you this morning.

What I want to know is this: Are you using these emails as bait to avoid the questions I have asked? What about Happy? Why cant you guys answer the technical side of this. Everyone are doubters until proven otherwise. I am a Scientist by nature. Dyno charts may convince some people but they dont convince me as I have owned and ran a dyno for years. Certainly longer than you, Mark, or Phil. As a result of that experience and my understanding of the dyno these charts where produced on, these charts do not prove anything to me.

The numbers dont jive from a technical standpoint. Thats all I pointed out.

Leave the slander out of this and answer the real questions. While you guys think I have it out for you that is total rubish. I dont have anything against you or the company. I just wanted answers. I guess I coud have emailed the question to you guys but it probably would not have been answered. Its obvious that I am going to take alot of flack for my questions. So be it. I want to know the answer and if others fault me for that they can piss off.

I know it can be hard to understand what someone is trying to say when their post is riddled with spelling and grammar errors. But why post if all your going to do is talk sh-it about someones intelligence? Are you perfect?

What bearing would it have on the discussion at hand if he is Clark Turner or not?

Ken

I sure hate to post in something that has gotten so personal, but let's point out a few things.

Happy says you can only get 420cfm @ 5900 rpm, but how is it that Al was within only 5hp of this car? Albeit with a VF30, but at a similar psi IIRC. If we did the math on other cars with near this whp, would it add up? Maybe the VE is higher on Teague's car, or maybe there is another factor not being considered.

As far as the calculator in TypeC's post, depending on the parameters, you can get a few different numbers. Without knowing the equations used in that calculator (it may or may not take VE into account the way happy did or what about intercooler efficiency), it is still possible to see ~450cfm @ 6000rpm since Phil or someone earlier mentioned that they were running over 20 psi.

It is clear to me that if we apply to same math to other cars running in the 20 psi range (with similarly capable turbos) that we may see similar mathematical results that run counter to actual results. Maybe using Delta Dash to log a few runs would be an easy way to show what is happening.

TRS

Look, I've already said that even a 10% disparity would be acceptable, but even this would leave you WELL SHORT of 400bhp @ 5900rpm.

As a comparison: On our engine @ 5900rpm, 85%VE, you would have to run 32psi to get 400bhp, allowing some disparities for VE, etc'.

Don't forget the relevance of RPM.

Now run 20psi @ 8000rpm, and the engine consumes 570cfm. Find a turbo, and associated parts that can cope with that, and you have a potential 400bhp, for REAL.......

Happy.

This is what fuels progress. NOT name calling, flying BS flags right and left and general ill will toward each other.
Al, you've admittedly taken a different path which makes your results nearly impossible for us to compare our results to. I know on paper some of these recipes don't add up but the fact is, until you repeat the experiment, who are you to nay-say? Teague has given us their version of the mod list, they have no reason to lie to us and both TurboXS and Teague have excellent service track records. You're certainly entitled to your opinion, I just think the name calling is a bit over the top.

I already have tested the vf30 - vf22 - pe1820 and stock tubos extensively with numerous different combinations of mods and compared hundreds of hours of datalogs and dyno runs

I think i am speaking from experience when I say that IT IS IMPOSSIBLE to make 335 wheel HP on street gas with a stock vf23 and stock block, stock head and stock cams on a 2002 wrx

It simply can NOT be done

Happy is a expert of Subaru engine performance - who to the best of my info is just an amature hobiest who shares info like I do - for free - with no financial compensation

While guys like Happy have been kindly sharing cutting edge tech info for years . . . what HAVE YOU done ?? All your good for is insults and slow cars - - - I repeat - what have YOU done special with YOUR car >>?

As for turboxs and the rest of the WRX cartel - i'm gald they are all making a healthy profit and a good business on these cars but lets not confuse a for profit vendor who is promoting its business with HP and 1.4 mile number claims with a end user who is digesting the results

As far as I remember - in the USA everyone is entited to his / her own opinion and its protected by the 1st ammendment - - even a primative tool like blkwagon here

If there are lemmings on this board who will believe anything a vendor says then let them keep on buying from those vendors

Maybe if you buy a MRT fmic/ fancy radiator, hks headers and vf23 with unichip you'll also have 335 hp at the wheels on pump gas ??? Somehow I doubt it !

Al since you and Happy are so good with physics and say that it is not possible with the stock block and VF23, give us good reasons why they would lie about it. B/c they wanted to show the capabilities of the unichip - promote thier product and knowledge

REclaim the record which I took from them with my 330 hp figure

And - becuase for years the auto industry has promoted products and cars with dyno HP claims

Todd,
Al is within 5hp of this using:
1)A PE1820 which is much larger than a VF23
2)An AVCS engine,variable cam timing. It has a more lummpy cams.
3)Lighter Forged internals and more Compression

Sorry, it just dosent add up. Even if they didnt touch the motor, the turbo just wont support that HP figure. And does their reason for taking the motor out sound like something any reasonable person would do? I doubt they could even make that HP by modding the turbo alone.

[QUOTE]Originally posted by Teague's Auto
[B]First off I am the one (Teague's Auto) who built the car not Turbo XS so if anyone has any build questions ask me.

Second we pulled the motor because the car was getting a Unorthodox Light weight flywheel and AP racing clutch. Now last I checked you either have to pull the motor or the tranny and since the motor was getting injectors, headers, up-pipe and inlet hose it just makes the install go faster on the motor stand. The motor has no cams no block work never pulled off the timing belt covers to look at the belt.

Third if the VF30 is such a good turbo why are my customers in Japan, Australia and the UK pulling it off for the VF23?

Fourth We used Shiv's up-pipe on the car because that was the only one I could get my hands on at the time and we had been waiting on parts long enough.

In the end it comes down to one thing. If you have the money and want the same numbers bring your car to me and I will do the same install I did on Jason's car and you can watch the whole install to make sure I don't lay my hands on the block, heads or cams. Then take your car to Turbo XS and have them dyno it.

This is just the first car like this we are building more so get ready to have more to talk about and if you have been tuning Subaru's for as long as we have since (1976) then you can give me a call and tell me how to do my job.

Dale Teague (Teague's Auto)

^^Thats good enough for me, ( I was waiting to see if Dale would chime in ). At first I too was skeptical with the dyno results simply because other people with similar setups have not obtained similar results. But I will say that I have yet to see another dyno run utilizing these exact same mods, and even still their are variations in tuner techniques that must be considered here. Therefore until we have a comparison using the " exact " parts on another car that was also tuned at Turbo XS we really have no way of knowing if these numbers are or aren't obtainable, so put your calculators to rest for a while. As for now I see no reason why we should not give them the benefit of the doubt, afterall we are talking about Dale ( Teagues Auto ) and Mark ( Turbo XS ) whom happen to both have exceptional reputations. Remember your innocent until proven guilty, these people deserve better treatment.
Tom
P.S. The best thing that has come out of this thread is that the C&R radiator works very well, I'm gettin one.:devil:

:lol: Take em to the water if you want, but you can't make them drink. This is why I rarely make these sorts of posts here. True, they are innocent until proven guilty. From where I'm standing though their trying to make a dollar out of .15 cents :lol:

Nathan, you should take that act on the road man. Could make some serious money making America laugh.

I still havent seen a complete list of mods. What injectors are you using on this miracle motor?

I wonder what the turbo engineer from APS would say about this.
They wont make any money with their new turbos if VF series turbos can perform miracles.

OBTW Tom, Turbo Evolution has a PWR alum radiator shipped for like $470 As opposed to the $700 C&R unit. I belive the additional cooling may be good for a few degrees more safe advance.

Ken Actualy the same compression - and as far as i know the rods and cran actually weight a tad more

But in any event 8,000 rpm sure helps out that powerband

STI compression is 8.5:1
It would amaze the heck out of me if the rods were heavier. But they are factory pieces so who knows.

Ken [/B]
Thanks Ken, I have been researching radiators for a while now and the C&R unit offered by Teagues goes for $640.00 and comes with cooling fans which the PWR does not. The C&R fans are reported to function 40% better than stock and cost somewhere aroung $170.00, so I think the price is acceptable to me anyways. Many people just don't consider the effects of cooling an engine as much as they think about how big of a turbo they can slap on. A cooler engine will always make more power and increase reliability, a good combination to have..
Tom..:)

Well, according to the formula Happy used, the turbo involved is irrelevant. Compression in the STi is 8.5:1 opposed to the 8:1 in the WRX--this is not factored into the equation either (as far as I can tell).
The only factors that I see involved are:

-----from Happy's post -----------
So, using the same equation I posted on the "APS turbo" thread,

121.7ci (1994cc) x 5900rpm x .5 x 85%ve div' 1728 = 176cfm (n/a)

x 2.38PR (20psi) = 419cfm.

419cfm is the maximum amount of air you can force into our engine at 20psi, based on a VE of 85%. 85% +/- 5% is the recognised peak VE of a turbo engine. This will vary over the RPM range, but sinse this equation is normally used for turbo sizing, it's conservative.

----------------------------------

Which are:
displacement (d)
engine speed (ES)
VE (VE)
pressure ratio (PR)

So, if this equation IS the limiting factor, the details about Al's run (or anyone else's) do not matter, and we're back to the same problem, which is:

420 cfm *.714 hp/cfm = 300 hp @ 5900 rpm

So no matter what turbo or injectors or intercooler or whatever you are running, the EJ20 cannot make more than 300 hp at 20psi!

Sounds reasonable, but it doesn't jive with a lot of dyno plots I've seen on here. I'm just trying to learn here...kinda wish I had taken some classes on motor design or performance. All this tells me is that there are some underlying assumptions to this HP/airflow equation don't hold for for these conditions.
