ROAD/RACE 4G94-Turbo Dyno Sheets!
Finally got you guys what you wanted. Had been waiting for Boe to get his car to the dyno for a Stage 2 Turbo run. Boe's car has everything we sell on it and nothing more. It is set to street STAGE 2 specs.
STAGE 2 RRM TURBO (Boe)
242 torque at 4700 rpm
233 WHEEL H.P. at 5250 rpm, 9 psi, 10-1 AFR
On 91 octane pump gas
ROAD///RACE SHOP CAR
272 torque at 4750 rpm
252 WHEEL H.P. at 5400 rpm, 12 psi, 11-1 AFR
On 100 octane race gas
Needless to say we know that going over 10 psi is a serious risk to stock internals, that is why stage 2 is right where it needs to be for most of the guys out there. These pulls were done on a dynojet.
Remember these are wheel numbers. Crank h.p. and torque numbers are going be higher in case these numbers do not impress you!

dayam thats putting down some mad power. So is this car tuned or is can you extract more power by tuning it some more. I'm impressed. That definetly is some serious power.

i just got one question... doesnt the stage 2 have an ecu? if so how come the power peaks and begins to drop off when you still had 500+ rpm left? is it just how the motor is or did you all tune it that way purposely? 
edit:thats a fat area under the curve

Tq will generally drop pretty good after peaking... factors like cams and vlv timing can make this drop less but it will still drop. As for the Hp once it peaks it is the same thing... way less though... if you want it to keep going up usually you can do so by taking out fuel but on turbo that's bad. I believe the af drops a little there that shows how it's getting richer and dropping the hp. Hope that answers your ??'s

nice AFR curve, too. Definitely in a safe range for these motors... maybe even a little conservative. No worries about a lean condition 
Congrats on the numbers, and thanks for posting them
