    502 MPI with Whipple

    I need feedback on the 502 MPI with the whipple blower. Most posts in the past was with the 500 EFI.
    Do you guys recomend any internal upgrades ( valves, springs, etc, etc)

    You forgot to ask him ...where about's on the almight dollar was this installation with Tyler.
    My guess would be hi 16's. That style will not fit in my boat....the new style is needed...and no doubt the new money

    I have a Whipplecharged 502 Mag in my 2000 Velocity 280. I have used it for about 50 hours with no problems. I bought it with the larger throttle body and installed an offshore water pickup and stainer at the same time. I haven't done any engine modifications and it is a stock Bravo 1 outdrive with shower turning a Bravo 1 30" non-labbed prop. I do not beat the boat AT ALL. I come out very comfortably at 2900RPM and cruise at 64MPH GPS@ 4000rpm. 98% of my driving is at less than 70MPH, although it will approach middle 80s gps. I have no regrets ...

    I have a Whipple on my 502 in my Crownline 225LPX

    I have had ZERO problems with my engine. The engine is completely stock (except for the Whipple).

    I highly recommend the Whipple to anyone with a 502 MPI!
