Default Re: 8K RPM on the LT-5

From the dyno runs I have seen, ZR-1s have a power peak at about mid 6's. Not sure you need to shift at 8k and risk valvetrain issue. As Todd noted, you would need to go to a shorter runner length in order to push power peak up to 8k.

Area under the curve is more important than when exactly you hit peak power. Mine reaches peak power at about 6800rpm but it stays at peak till at least 7400rpm - as high as I've revved it on the dyno.
