I have an all stock '00 GT that I am going to the track(1/4 mile) with for the first time this weekend.
I really don't have the time to dyno the car, or try different things at the track(bracket race day), so I was hoping some of you guys could help me out.

The car is being raced in all stock trim including the 3.27 gears.

All shifts will be full throttle powershifts.

I have made 300+ passes in my '93 car, so I consider myself fairly experienced.

If somebody has dyno numbers from a '99 up stocker instead of track experience, I can work with that, as well.

Any guidance would be greatly appreciated.

Thanks,
Joe Correia.

Well personally I think dyno numbers are overrated and the track tells all but that's just my opinion. Stock GT's usually make peak power at 5250 RPMs so if you go by the general rule of thumb of shifting at 10% higher RPM than your peak you should be shifting at 5800 RPM to keep the car in the power range longer. I got the best results out of my car in stock form by shifting it at 6K RPMs.

From my experience, on a stock PI engine, it doesn't make much difference. Shift somewhere between 5,500 and 6,000.
