Thanks Nathan and Jermaine, and I hope your trip goes well...

def

Thats a lot of power and only 208 ft/lbs?

nvm, typo 308, that sounds more like it.

oops... yea, 308. Fixed.

def

22psi? daily driver? lol thatd be lots of fun OH **** COPS! RUNNNNNN lol

Let me ask you a question. I know you love the new hawtness, but honestly, which setup would you say is a better street setup (with occasional track days; no drag).

I ask because I will soon be looking to decide between a very similar setup or staying with a VF-36.

Nice numbers doug. Can't wait for the race gas tune and the E.T's!

Interesting now that I got to see your dyno sheet. I was thinkin of the Superzilla but got a Green and was left trying to figure out if yours was going to be more drivable?

We look close on when the HP starts to hit as I only made 380WHP but I made 350ft-lbs mid 4k.

I just have to get my clutch fixed now so I can pull a decent ET :(

Sweet setup. :cool:


"JIC Full Titanium Catback (w/2.5" bottleneck @ flange)"

Yeah I had the same problem, don't know what the JIC boys were smokin when they designed that. Also, the doughnut flange on the JIC (Magnaflow in my case) would not seal with the flat flange on my aftermarket DP.

As beautiful as that Ti pipe is, decided to have it cut about 4" from the end. Had a 4" long 3" diameter pipe cut and welded to a 3" flat flange. They wrapped the joint with a soft sheet of metal and used some plates and bolts to clamp it on. It solved the leak and bottle neck for about 40 bucks.

Different dyno's, different numbers ;). I know Turbo XS runs SAE corrections on the hp side of the graph (which Nathan told me gave me ~7whp or so), but their torque graph is UNcorrected. Looking at your graph, either both hp AND torque have been corrected.... OR neither have been corrected, because your graphs cross almost perfectly @ 5252 rpms.

Mikaust made just under 300 ft/lbs with his 8cm green (no AVCS). It was clipped, too.

I guess the 7cm housing is helping you spool pretty good. My torque peak with the 8cm housing is @ 4700, looks like you fall right about in that same spot.

I too can't wait to get some ETs... maybe you can come down to Cecil on opening day. I have been kinda making it a Subaru tradition for the locals. Should be sometime in February.

Eric-

Thanks! Again, I can't wait either. So whats up your sleeve, I see you've improved to an 11.8 @ 117... still stock turbo? If so badass... if not, still badass... lol!

javid-

I actually took it to a shop and told them and showed with a diagram I made what I wanted them to do. The test pipe and cagtback flanges were completely off. I wanted them cut off... and a 3in piece clamped in. The went the extra mile... cut the test pipe, rotated to mate to the catback... and left in the restriction. They did a good job, even though it wasn't what I asked.

Anyway, I have a plan for it... similiar to what you did...

fragment-

I loved the VF36. It made the car almost feel NA. Seamless power. But now with the 'Zilla... I think I got it spooling pretty quick, I just love how it pulls...pulls... and PULLs. It just feels so much stronger WITHOUT sacrificing all that much in terms of spool up.

def

Doug's set up is sweet. It spool's quicker than my green (My AVCS is not working). The power is very smooth. The only problem he faces is how to deal with the stock tranny till he get the Turboxs dogbox. :) Great tune Nathan and Jermaine.

I emailed Cobb a short time ago and they told me they were selling there dog box since they rebuilt it but decided to go with a 6 speed now.

Yea still stock turbo, stock IC etc. Waiting for this buschur turbo to come out. Then I'll be down at TXS. Maybe I'll make a weekend out of it and we can hit up the track.


ERIK

looks like your torque curve is pretty peakey. any way to get a turbo to hold out the tq till 8.5k+??

looks like your torque curve is pretty peakey. any way to get a turbo to hold out the tq till 8.5k+??

Anytime you make POWER... its almost ALWAYS gonna be peaky.

Lets say the torque stopped at 200 ft lbs.... draw a line straight across. Nice and flat right? But look and see what you lose.

I have on tap more torque than a stock WRX does EVER @ only ~3800-3900 rpms. Whats a stock WRX torque peak rpm? 4000? Well... in that case, I think its pretty good... ;)

And horsepower wise, I am making more than a stock WRX EVER does at a mere 4800-4900 rpms, or in other words I make the same hp as a stock car does @ 6k... at only 4.8-4.9k, In that regard, a stock car would seem peaky.

The numbers can be taken and viewed however you want.... but pah-lease try to see them in context. Driving it is just plain awesome... this coming from a guy that ran a twinscroll VF36 super spool set-up.

To hold the torque out to redline, your asking for a MUCH bigger laggier turbo that will make the torque ALL that much more peakier... or you want a turbo-diesel that redlines @ 3k.

Which turbo? They have a few out... what one you waiting on, a BR700? ;) lol! Let me know when you go down...

def

*oops i posted under the body shop name*

they are producing an upgrade to the stock 16G. Pretty much makes it a twin scroll 20g. titanium/aluminied wheel, 10.5 turbine housing and 20G compressor wheel. :devil:

Should produce 400whp on pump with stock like spoolup.

Can i ask how much timing you are running ??

I have a AVO500 with a 2.5L block with standard TMIC and can only run about 12 degrees of timing on 1.5 bar, is this normal ??

Is your external wastegate connected to an atmospheric dump tube or plumbed back to your downpipe? Seems like everyone doing the Superzilla is going with an external wg....I'd be interested to see results with the internal. :cool:

I am pretty sure the 2.5 block runs alot less timing than a 2.0

My 2.0 generally can run ALOT of timing and get away with it. I haven't looked at my maps yet, but I wouldn't be surprised if the timing was in the high 20s or low 30s up top.

I am going atmospheric... I love the external.

Although there is added cost with externals... the benefits to me are well worth it. SOLID boost... no creep... and the BSFC drops a few points as well. And oh the aural pleasure... lol!

def

Sounds about right, Hybrids and STI's pushing 290+ g/sec are easily in the teens for timing on pump gas. I top out at around 17 degrees at redline, but about 14-15 in the midrange and 5's.

Well I have stage 5 and a lil extra.....The normal stage 5 has GT30R, 780 cc injectors, up pipe with ext gate, custom dp, Ecutek...ect...ect, but im runnin a GT35R (lil laggy but hella worth the wait on a 2l) with the rest of the stage 5 kit and some other goodies :)

Should have the motor in and tuned soon....I plan on running 22 psi with 94 pump.


Scoobs

What setup was used for the baseline curves on your graph?
Are they from your car?
They almost look like stock US STi numbers, but the torque seems low for that.

Thats what I had after they worked with the fuel enough to actually get her to rev out to 8k.... so essentially that was the first CLEAN full pull.

def

Damn, first clean run was at 231 hp and 204 ftlb and you ended up at 373 and 307. Thats seems like a good day of tuning to me.
If you take her out to 8k and shift where do you end up in the next gear?
Seems as though you need to find that sweet spot to shift so you end up right at 4500 rpm in the following gear, while also staying out of the massive power loss after 7k. Or does the horsepower take over once you are moving and the torque drop really wouldnt effect your times?
I still dont know all the relations between hp and torque, but it seems as though staying in the 4500-7000 rpm range would be ideal.
Any plans to run a small shot of NOS to get her off the line and get the turbo going?

Thanks
Ron

Its quite responsive and as such, N20 wont be needed. Just a little launch control set to 6100-6500 rpms (once I get the dogbox anyway).

We can get Mikaust's FP Green out of the hole pretty clean and as he sits, and that car is laggier (got some AVCS issues to work out yet).

As for shifting, I am prolly gonna take her to just shy of 8000. Normally expect about a 2000 rpm drop, shift to shift. That varies obviously depending on gearing.

In every set-up I have run in my car, shifting at redline has ALWAYS yielded the best times for me. Even when I was running the piddly 13G I got 13.09 @ 103.1 shifting just past 7k on the EJ205.

On my old EJ207 and VF36 set-up, I shifted @ 8100 or so, and managed 12.0 @ 115. That set-up by no means held the power to redline like this one does.

With the VF36, I had 190 tq @ ~8k. With the 'Zilla, I have just over 220. Pretty big difference there.

Essentially torque and horsepower equal one another. They are just different ways of representing the same thing so to speak. Horsepower calculates from torque over time, thats why it tends to trend up when the torque is dropping off.

You would expect that larger bore to need more timing advance.

You would think that but unfortunately it don't always work out that way :( Look at a motorcycle or even the S2000. They have lots of timing and RPM because a smaller chamber allows you to lean on them more. A big chamber is more prone to detonation ;)

They're naturally aspirated. The amount of timing the 2.5's are taking seems to me atleast, to be dependent on the heads. Jeff's car, which has V8 heads, looks to handle decent timing relative to the airflow, while V6 headed 2.5's do not.

I smaller bore will let you get away with more. If you think the 2.5 has worse heads then put a set of V7 heads on your block and see if it makes a difference :confused:

How in the heck does your BSFC go down?

Your dumping a crap load of exhaust before the largest restriction in the exhaust stream, ie- the turbo, thus efficiency goes up, BSFC goes down.

Maybe not by much, but it does.

def

BTW- your old 20G turbo was in just ahead of me @ Turbo XS Saturday. I think they muscled out 312 whp on pump gas. Best pull was 316whp, but they backed it off abit. I think boost was 20-21 psi.

Thats funny, my injectors also. I made 321 on pump, with hks downpipe, 5zigen catback, and greddy fmic. And that was with the boost leak :-). As I recall he had a turboxs tbe, and turboxs frontmount.

Not really. Most notable differences now are the intake manifolds and exhaust manifolds.

26 psi is childs play for WRC. If you are a rally racer and AREN'T a speed freak... you'll soon just be a rally fan.

Any rate, Bryan's old set-up ran 26 psi on racegas... I am running 21-22 psi on pump gas.

You're missing the Subie set-up? Well... soon after X-mas would be a good time to start over again... :devil:

nah .. gonna stick with the neon build. I'm hoping to go 10s before the summer is out. The turbo I have right now is only good for 50lbs/hr, but I have a hundred shot to back it up.

You're gonna need a little over 500whp, the right gears, and a 1.5 60'.

DEF,
My Blitz SBC-id also reads a couple psi high. I think mine was reading 21-22, while the ESX gauge hooked into their computer was reading 19-20.
I'm pretty sure it has to do with the crappy little plastic line that comes with the Blitz unit. Both of ours are probably crimped in one spot causing a little pressure increase in the line. Or the line is melting together and causing the same phenomenon. I have had my line melt in half 2 times. I was surprised at the lack of quality of some of the pieces with the outrageous price tag of these boost controllers.
Live and learn i guess.

If I remember correctly, my SBCiD read pretty much dead on with the Dyno last year when I was tuned. This year, TXS, didn't hook up a psi reference to the dyno, all we went off of was the SBC or the UTEC.
