im guessing around 6500-7000rpms

well the stock engine drops off in power after 5500-6000 so why rev it higher than that? P&P and you can worry about dropping valves and such.

there is a vid around on of my friends houses somewhere of me and a friend on a dyno & you can hear a valve floating on both our cars at about 5800

whats a floating valve sound like? i want a dyno tune, but i dont think i want my engine beat on that bad.
