Hi!

I am building a 500 whp GT86 and deciding between the Piper Stage 2 and Stage 3 cams. Does anyone have experience with either cams?

The engine is an Element Tuning 10.5:1 Big Valve FA20 block with a G25-660 0.92 AR turbo kit from JDL, revving to 9000rpm. Also with FMB's improved intake manifold.

The application is time attack partly and a daily as well. Yes, I know.

The goal is to have a good balance, have power from 3500 rpm, not a trash useless 2000 rpm like in a full race car. The turbo has the bigger AR to let the engine rev high.

Does anyone have experience with either cams? Counterspacegarage said the stage 3 is fine for this goal, but my tuner says the stage 3 will completely destroy low end - even though he never installed a Stage 3 cam on a FA20 but has Subie experience.

Thanks for the help!
