    solid roller cam specs for 509 whippled/cooled

    going through the motor in my 25' ultimate warlock sxt cat, stock 502,
    hyd. roller (stock) w/ a whipplecharger/whipplecooler setup making 6lbs
    of boost. never set up a motor for an outdrive , and I know I'll only need
    to rev it maybe 5500-5800rpm. new comp ratio will be about 7.9/8.0to1
    had 8.75to 1. should I stick to around 230/[email protected] on a 112 or 114?
    or should I, could I go bigger? the bravo 1 IS the weak link in this setup!

    Leave the cam alone and crank up the boost. 6 PSI is nothing, and it'll be even less with the compression loss.

    With an inter cooled Whipple, you can throw a TON of boost at it.
