    Maybe a 14/19. Run it first and see where your rpm's are.

    Seagoat - would be interested in knowing why this impacts that. Are you looking to INCREASE rpms' or decrease.

    I ran 73.2 this weekend at 8100rpms. Intercooler, minor exhaust changes and grate are the only mods.

    Did you repitch your oem prop or did you not need to.

    Repitching isn't really difficult. Just go slow and easy. If you bend it wrong (like I did ) just unbend it and start over. My first try turned out pretty good, if I don't mind saying so myself.
