Got a chance to tune an STI on sat, This car belongs to Chris of Arizona dyno chip. This car used to run an ECutek tuned by us and a full TB exhaust. Chris installed a new custom exhaust that uses a 4 inch DP into a 3.5 inch pipe that turns down under the car. Its a tuned length system based on some math his friend came up with. I was shocked at the fact that this system was not that loud. It dumps right under the car and has a real throaty sound.

The car made 281whp on the ECUtek tune on pump gas. With the new exhaust and a utec I was able to tune it to 300whp at only 17 psi. I dont have that chart handy but the trq increase was substantial.

Then we decied to tune the car out on C16. Chris road races so I left this one nice and rich at 12 to 1 AFR. Boost on these pulls hit about 20. The car made so much trq I decided not to tune further. The car went 12.2 on the ECUtek flash so we expect this Utec tune will put him into the 11s with some practice. This dynojet is one of the lowest reading dynojets I have used. In fact in a same day test it was 10whp off the dyno dynamics. Not sure why. 325whp on this dyno is flat out incredible and 382ft lbs of trq makes me dizzy.

This engine is stock and uses the stock TMIC and related parts. Chris can list mods.

Old ECUtek tune vs Utec tune.

if only that turbo didnt suck ass up top. sigh.

awesome numbers, though...ESP the torque :eek:

Congrats! Those numbers are sick. :huh:

Wow, that is really impressive on a VF39!

Chris should start manufacturing that TBE.

very nice.

Man, that really shows what C16 and 12:1 af compared to pump and safe tune can do. And a good tuner as well ;)

That's great I think I need to make the trip to get re-tuned

mods pulease :disco:

^yea im very interested as well (injectors?)

Wow, that is really impressive on a VF39!

Chris should start manufacturing that TBE.


I agree. :D

cough modlist cough :eek:

damn
impressive :D

Awesome..

bump for modlist...


chris

Can't wait to see what you do w/ my forester! :D

mods pulease :disco:
Sorry for being slow on the uptake, the mods are as follows:

GTSpec header - HPC coated
Perrin Uppie - HPC coated
TXS DP cut halfway, 3 bolt 3.5" flange
Magnaflow 3.5" race series muffler
HPC no-blow 3.5" - 3 bolt gasket
ProfecB
UTEC
K&N drop in filter
Clark + C16
AP Short shifter
Sparco seats, harness and wheel
Volks + RA1's
Autopower roll cage

Everything else is STOCK - block, internals, turbo, intercooler ect....

Wow, that is really impressive on a VF39!

Chris should start manufacturing that TBE.

If your serious, We can possible "jig" it and make some. I can tell you that I have $700 just in materials alone - 3.5" stainless is F-ing expensive - had to get from SoCal.

Its actually better grade stainless than we get locally, it welded sooooo nicely!

Hey Tanx Clark for postin the graph and tuning the snot out of it!

Can i take it one step further and ask for a pic of that exhaust??

Can i take it one step further and ask for a pic of that exhaust??

Will be a little while before I can get a pic for you, preping the car for the LA trip to the GT Champ Race.

I will tell you that I am already planning to revise the muffler, as it hangs a little low. Might try Magnaflows oval race muffler design.

Not bad, only problem is that he's effectively shifting down to 5500 on the 6 speed, meaning he only has an effective 300 lb/ft. But for the time he's in 1st gear, or lugging a gear coming out of a turn... that's just sick.

Soo true.....I went to the track that night and now the car acts totally different! I need to learn how to drive it all over again, and I need to set my shift light at 5500 RPM's so I can stay in the sweet spot as much as possible.

I have also toyed with the idea of skip shifting to allow more time to hit higher peak boost.

UTEC on top of the Ecutek reflash? Or did you toss the Ecutek in favor of the UTEC??

Couldnt you have tuned the car to make the same power w/ JUST Ecutek?

Good numbers anyway.

UTEC on top of the Ecutek reflash? Or did you toss the Ecutek in favor of the UTEC??

You can't have two maps with ecutek. Only two boost settings.

UTEC replaced the ECUTEK - So I can have multiple maps to choose from - street pump gas, race pump gas, street rocket fuel, race rocket fuel!

If we tuned the car with just ECUTEK, I would have to run the same mix of fuel all the time.

Just further proves that the intake IS NOT something that needs attention when running a stock turbo.

Oh my, where are all the naysayers now! I've been saying for a good year that the STi, especially when modified, needs a smaller final drive ratio to effectively land you into more of that sweet spot of torque.

Hmmm... ;)

I don't think that *proves* anything. It would be interesting to see a new dyno chart with a highly rated intake (ie Typhoon) and see if any HP or torque is picked up at this point. I am not arguing that it will or will not, just that good numbers with stock intake doesn't mean further improvement is impossible.

I agree, I would love to try an Typhoon and see the results.

I can tell you a long time ago on a dyno, I tried an Injen CAI and TRUE it made more power, but it leaned out the A/F and the A/F line was anything but smooth. It looked as if the MAF was trying constantly adjust, never finding a happy place.

Clark and I have both said for a long time that the stock air box is good for 500-600 hp.

could you post a picture of your exhaust, it sounds really interesting...

Yes I will try and get some pic's when we return from LA for the GT Championship.

Any chance of sharing a map for those of us who are not blessed with a good tuner in any of the nearby states? I tune myself but am no good without some sort of base map.

Is C16 110 unleaded?

c16 is 117 octane and leaded iirc.

I take it leaded is safe provided we are catless?

That would depend on how you define safe. =] Your O2 sensors will eventually fail and need replacement but otherwise all should be well assuming the local pd doesnt pick up on it.

But it smells SOOOOOO GOOOOOOD!

The maps belong to Clark, its up to him if he wants to share.

One note - we are at 1200 ft and the map may not preform well at sea level, also I am running pretty much a tuned open exhaust, completely different from what you can buy off the shelf.

Props on the car, those are some sick numbers on a fairly stock engine.

I love the smell of c16 in the morning. :devil:

I love the smell of c16 in the morning. :devil:

Tell me about it - I first fell in love with leaded race gas in my 14:1 compression '76 Corvette.

Just love that stuff to death!

Did you do anything to the stock airbox besides adding the air filter? Like removing resonators or anything like that.

Did you do anything to the stock airbox besides adding the air filter? Like removing resonators or anything like that.

Yes, resonator removed, elbow cut off to get air from the fender.

12.1 AFR on a stock intercooler and no water injection. Incredible. I'd like to see the timing, I won't argue with the results.

Gots a new digicam for xmas, postin pix soon

Pics from the ground....sorry no lift access today for better shots.

It hangs a little low, so we added a mini skid plate! Isnt it cute?

man that thing looks as if it came off a truck lol... man the things u do when u have .5 more liters.

With the delta dash board you can swap da ECUTek maps.... ;)

Very nice numbers... To bad the turbo cant keep up on the topend, but that torque makes for some fun low speed driving...

Junior

I wonder how that car would respond with a VF-34 or an 18G, leaving everything else the same... It might balance things out very nicely!

Too bad i built that exhaust just for 3 races, Blowzilla should arrive this week or next and after the race on Jan 30th we tear it all down and build a whole new one for the Garrett set up.

At least it was a good test - expensive - but good!

Let me know when your rod bearings fall out ;)

Let me know when your rod bearings fall out ;)

Fall Out?????

HA...HA....HA....HA!!!!.....I plan to melt them right into the oil pan!

:lol: Nice! I hate people that do things half assed.

Thats some pretty good power you got there. I would love to see some numbers from the track. I would also like to see the setup survive for 50k miles... Seems all of the guys that have made big power initially have all pretty much died along the way.

~v6

stupid question to you guru's but wouldn't a setup like this with sustained high EGT's on the track cause some sort of failure to make this set up unreliable. wouldn't this set up only be good for a short drag or something?
just trying to learn :)

Well if it makes you feel any better, the car has 35,678 miles on it now.

It will click over 36k before I get Blowzilla on!

Yeah thats what im saying... 20psi out of that turbo on a road course? The thing will be glowing red within the first 2 minutes I bet. I know my WRX stock turbo got BRIGHT ORANGE and the up and downpipe were glowing also when I was pushing 18psi.
No doubt that the STi turbo is equally out of its range @ 20psi. They both only push 14.5psi stock iirc.

Who said anything about high egt's?

My egt's never peak 1400!

More like 1375 at redline.

Plus at a 12.1 a/f it should stand the test of time!

Was it stock for the majority of the miles? If not how fast was it?

~v6

well 35k unmodified? :)

i have 20k on my sti but only about 5k with my stage 2 cobb. so far very reliable with this cali piss gas. i guess i'm trying to validate the bearing issues i keep reading about on these forums.

wow you guys are quick... i was still thinking about my reply

Well the reason I mentioned it is because I hang out with one of the members that lost a rod bearing recently. The car has less mods than horshack does presently, and less miles too. Tho his tune might have been more agressive.

not that I think its going to happen to his car, but I would like to see what happens. I pray it holds together because thats good news for me. At this point I have seen enough failures to keep my car stock...

~v6

thanks v6

np :)

Let me know when your rod bearings fall out ;)

Did somebody say rod bearing :lol:

Didn't this car already run a low 12?......You guys think this maybe the first 11 second 1/4 factory turboe'd STI? :banana:

True....I got the 3rd car to be delivered to AZ.

I instantly put a TBE and K&N drop in on it.

Later I swapped Uppies and a Header.

Strut tower bars, end links

clutch, wheels and tires.

oh and race rear axles....hee hee

been like this since 18k miles and ran a 12.23@113 before the UTEC and race exhaust.

well 35k unmodified? :)

i have 20k on my sti but only about 5k with my stage 2 cobb. so far very reliable with this cali piss gas.

Yeh....I went to LA for the JGTC and we drove there after the tune, and as soon as I filled up in Cali - instant knock!

I cant believe that the tractor piss here in AZ is better than the tractor piss in Cali.

I had to crank the boost way down to avoid knock - in fact I still have a 1/4 tank of that Cali tractor piss!

Not for nothing but I wasnt refering to you mark. Your the 2nd case I know of.

Most shops wanted to just R&R the motor...but i went to place that will remove and tear down the factory unit, this way i'll know exactly what broke and make sure it don't happen again :)
S*** breaks when u make 425WHP/460TRQ :lol:
Sorry, a little off topic

do you think that a muffler that close to the turbo could cause too much backpressure?

Yeah you were probably making 100+hp over the other guy I know of that tossed a bearing.

Most shops want to get paaaaiD for the labor, rather than you buy the shortblock somewhere else... i assume :lol:

I cant wait to see your car once you get it back running again.

Yes, thats the plan - to hit at least 11.99 with the stock turbo.

then BLOWZILLA hits the shores, to deffend us against the evil MOTHRA!

do you think that a muffler that close to the turbo could cause too much backpressure?

What back pressure?

That muffler is a true 3.5" ID perf tube - straight through - you can drop a soft ball right through it!

So when you had it tore down what happened?

I have a good guess that it was probably oil starvation and spun a bearing.

Couple of things to remember guys. At lower rpms that stock turbo is in its range still. Its only till higher rpms that you typicaly run off the map and over speed the turbo. This car even with my tricks had some healthy drop towards redline. Its being pushed for sure but 20-23 psi at 3500 does not scare me or the turbo :) EGT's on this car where actually pretty cool. That is due to the short exhaust. This thing dumps right under the car and its 4 inches at the smallest point its 3.5 inches. It was an interesting tune with that exhaust to say the least. It really opened things up. Also. With C16 fuel at 12 to 1 AFR I would have no problem road racing this car at this power level. Those rod bearings will be just fine unless it knocks. This car will run 11's if he can get some good passes in with a sticky track. 11's on the stock turbo would be neat. He has alot of power over his old tune that got him low 12's. The real problem is that the 6mt is not geared for this type of power band. Alot of that trq is missed going down the track. The Blowzilla should be fun. I expect power will jump up to 400whp pretty easy with about 360-380ft lbs.

Clark

so what kind of tranny do you recommend for this type of powerband?

if only that turbo didnt suck ass up top. sigh.

awesome numbers, though...ESP the torque :eek:

I agree... I hate the fact that the STI's torque band falls flat on its in face after 4000RPMs... But hey, with an FP Green, 800cc injectors, 255lph fuel pump,
and a little tuning, should see numbers in the 450AWHP range...

Awesome numbers though... Thats impressive for a stock STI !!!!

I dont recomend a different trans. I recomend more top end power. It was to prove a point that the 6mt really holds the revs up high and alot of that trq is missed.

I have a VF34 sitting here. If Hoshack wants to toss it on for a test He can use it. Might be interesting. I think it will hit about 340whp. I got a 2.0 with a VF30 to 340whp so I know there is at least that much in it.

Clark

Do it horshack!! :)

I have seen a few STI guys goin to a vf34...it was worth between 13-16 hp @ the wheels.

i want to make an exhaust like that, but i was thinking of using a 3 inch dynomax...i didn't know if it would cause any backpressure or not...

i want to make an exhaust like that, but i was thinking of using a 3 inch dynomax...i didn't know if it would cause any backpressure or not...

Well understand one thing - with a turbo in the exhaust set up there is plenty of backpressure to create the scavenging effect from the head.

Back pressure on the back side of the turbo is counter productive, it creates resistance for the wheel to spin against. Though a total elimination of back pressure on the back side will create a "back fire" effect at every shift and decel. The trick is to find the sweet spot and target the length there.

Hey C,

Do you think givin the vf34 is worth tryin? Will it make that much difference up top?

I think it would be better to swap it out with a vf22 though

If so, after we smooth out the transition Saturday afternoon, I will run the rest of the Cali Tractor Piss gas out and get some c16 and we can do the swap.

Where are you located? Do you premade dyno tuned maps for specific mods?

IE Do you have a stage 2 map dyno tuned for a catless exhaust and short ram intake and 92 octane?

Well once we both have a few hours to kill and are bored to tears we may take a stab at it!

So when you had it tore down what happened?

I have a good guess that it was probably oil starvation and spun a bearing.
The motor will be torn down some time today or at latest Thursday....

I maybe goin over to a gt30-13 or 14 :banana: and dumpin the green

That exhaust is tits!

so what kind of tranny do you recommend for this type of powerband?
Stock WRX 5-speed. It's got nice tall spacing between the low gears. Should hold the torque no problem.

I actually put down more trq then this car last time on the dyno. 390 something ft lbs. My 5mt is not broken. Plus on the dyno I only ran 1.6 bar but on the street was hitting 1.8+ which probably puts trq up in the low 400's to the wheels.

Hey C,

Dont you think I would just destroy 1st gear at the track with a 5mt?

Scary!

That exhaust is tits!

I have decided to sell that exhaust after the race on Jan 30th.

I was going to use part of it for the new Garrett set up, but have decided to build a whole new set up.

Maybe the new set up will exit from the passenger quarter pannel!;)

Hey C,

Dont you think I would just destroy 1st gear at the track with a 5mt?

If you got a strong one no. I used to cut 1.6 and 1.7 sixty fts with my 5mt. It was abusive to say the least. WOT. Off the clutch at 6000 and flip the nitrous on with my left hand. Your gear ratios will be perfect when you get the Blowzilla on.

To give u guys a update...i know horshack asked before.,
My motor was torn down and...

1 Badly spun bearing that pretty much wiped out the crank
1 Con. rod bearing on its way out
2 bad Con. rods
:(
And a whole lot of oil in the intercooler maybe indicating and piston/ring problem maybe??

The cars now gettin a fresh factory short block +
Forged pistons
treated con. rod bearings
ARP head studs
maybe rods??...
I'm also thinkin about going over to a gt3013-or 14??

nice! bigger and better was an understatement ;) good luck w/ the new setup. what was the best numbers the 39 made on pump?

Why didn`t you use EcuTek+Utec, Like a combo, did you Re-flash your ECU back to stock?

If that comment was directed to me....I am using ECUTEK and UTEC.

Mike knocked down my hot reflash back the standard STi flash and then Clark tuned the UTEC on the dyno - took about 45min on and off the dyno....it was a very fast tuning session.....we kinda snuck in between customers so we could stay on the dyno for very long.

I am curious to see what this does at the track compared to the vf39'd wrx's from puerto rico. I believe they were 300-350 whp on c16.

I am still waiting on parts and cash. Da wife spends it faster than I can! :lol:

On using the T04R. I that the HKS T04R?

On using the T04R. I that the HKS T04R?

Yes - its a Garrett turbo made for HKS to their specs.

Update is raw good material for parts is getting harder to come by with the war and the new Boeing and other airplane manufactures snatching up all the raw materials.

Now its sooo hot here in phoenix, it might wait till fall.

Ok. Let me know how it goes.

Ok. Let me know how it goes.

U must really be interested in the TO4R, for me this turbo is only temp - once the motor pops - the rebuild will include headwork, intake and a 10k rpm bottem end - all to support the new GT40R.

All the pipework I make for this kit will cross over to the GT40R with little modification.

Yep. I has been very successful on the supra and skylines.

I am very interested in the twin scroll turbo too, which the hks also have.

It is good up to 700PS and would be interested to see how it compares to the GT35R and GT40R

Its just above the 35r in lbs/per min, but uses a t4 hotside to flow more gas than the t3 hot side of the 35r.

Now there is a huge jump from the 35r to the 40r, I would estimate that the TO4R is just above the 35 but way under the 40.

Soon enough Kingpin will have plots and data on all of the combo's. 30R, 35R, TO4R, 40R, T6x......and who knows the T80 even.

Yep! He is currently building the kit for market. I cannot wait to see how it performs.

At present, the BV guys are still using the GT35R up to 700+whp.

I haven't check out the turbo's yet, since I have not decided what to do w/ my engine.

But the HKS is very well know, except for the Subaru community which uses turbo from subaru markets.

Thanks.

Correct, my kit will be a little different than the production kit, as mine will not mate to the stock exhaust, also I am using a 4-2-1 header instead of an uppie from the stock collector.

But the base maps will be that same.

Justto give you an idea what I have to work with so far:

Thanks to Kingpin for sourcing all the parts and materials!!!!

There is soo much more coming too!

that snails looking pretty big.... :devil:

honestly guys your interest has given this project new life.

After spending the last month helping friends with motor swaps and clutch jobs and a whole tranny rebuild - the heat has gotten to me.

I didnt want anything to do with the kit, at least not till fall when it cools off.

I was actually thinking of selling the parts I have and just racing the car as is, but after some additional pondering I have renewed interest.

I will be ordering the rest of the stainless week after next when I get back from a family vacation.

That header do not look like it is a twin entry one.

Glad to here that you have a renew interest.

ooooh a t04r........that would be a cool turbo for this car........

Not yet its not a twin entry - it needs a little modification! :devil:
