i will note that the cam and the turbine housing a/r are generally considered unorthodox for a turbo street application, but ended up working great like i thought. the power curve is very easy to handle as it is almost like a centrifugal blower car but with alot more torque.

Im amazed at thoese numbers. I think something is amiss. I cant imagine how a turbo kit even made by God would make that amt of power at 4.5 psi. Even if ur secret cam is gigantic something dont add up. Most are around 8psi and 500 rwhp. So spill the beans!!

Large turbos, make more power at less boost than two 28's or 30's that people typically use. Not too often you see a set of GT35's strapped up to a motor, a stock one at that. Those numbers seem possible with that setup. Of course...they could just be icing the **** outta that intercooler too....

My theory is that the big cam is just making the VE so high that the boost numbers appear low. Plus, what the other guy said, i'm using larger turbos than most people use on a stock motor setup.

Yes, but I swear it's not a happy dyno! Several other vettes have dynoed their with very realistic numbers, and right before I dynoed a Supra I know made very conservative numbers.
