Here's what it made on our Dyno Dynamics "Heart Breaker" dyno:
407whp/404wtq on 93 octane @ 19.4 psi


461whp/461wtq on E85 @ 22.4 psi
*Unfortunately, we ran out of fuel pump on the E85 tune and couldn't push the full potential. Round 2 E85 tune coming soon

 

Why all that work just to run numbers you can run on a stock motor and fp green?

 

Well...

My build 07 STI with a 35R did 410 on S&R @ 19 psi... From what Ive seen there dyno reads a bit higher then mine seeing there was a 45whp difference the other day comparing our 2 dyno's with a subaru ...

So I'd say your dyno's not really a heart breaker... More that Scott doesnt tune cars for power. more for safety

 

Stock STi's make 200-210 whp on our dyno. Everything that we've compared from ours to a dynojet has been at least 15% higher.

When do 35Rs on straight 93 ever put out big numbers?

You, S&R, and Forged should get together at AWD #6 and race your dynos.

 

Alright, thats right on par with mine then.

Car must go well.

 

Did I say anything about pump numbers? And plenty of cars make over 500whp on pump 35rs, Why build a motor to that extent to run 22.4psi and also run E85? You could run 22psi on pump gas.

 

nice scott.. i really like that cosworth intake.. worth the $$?

 

There aren't any SUBARU's making over 500whp "Dynojet" on 93 octane. Stock head and cam 35R SUBARUs usually make 415-430 on 93. With heads and cams you can do 460-470 on a 35R on 93.

The 22.4 on E85 was were it maxed the fuel pump, but it's currently getting a GORGEOUS Surge tank / twin Bosch pump setup to go for 600 whp
