    Supercharging a 155 RXP???

    I have an 07 RXP 155, I rode it this summer for 45 hours completely stock and I love the thing, but I would like some more speed. Does anyone know if it is possible to put a supercharger and intercooler on one? And if so, what other mods should I make to make sure it remains reliable? (Im not looking at doing anything drastic, maybe an x-charger?)

    Short answer, don't do it!

    Welcome to the boards...

    SC'ing that ski is more work that you could think of, you'd be better off trading it in on a SC'd unit instead...

    thanks guys, so what mods would you recommend that aren't too expensive and will give me the best increase in speed/performance?
    and just a little side info, im 16, and my dad bought the ski, we were supposed to get the 215 but he's cheap and all and the dealer offered a good deal...damn

    You need to contact PPG for the prices. My guess is that it will cost more than to have bought an RXP/RXT to begin with... Ron

    All is not lost. You could do plenty of stuff and get decent performance out of it. Keep in mind that the GPR's only come with 170 hp stock, so it's not that far behind, though it'll probably never hit 80 mph. Things you could do:

    Riva Grate
    Riva Wedge
    Solas prop (pitch???)
    Jim's rideplate
    4" air intake
    Through-hull exhaust
    Riva or shorty waterbox or Magnaflow
    Thermostat
    Fill rideplate holes
    Trim reverse bucket

    I think these run upper 50's stock, so the mod's should get 65'ish mph. Thoughts, guys?

    What rpm does it turn?

    Perhaps a 215 ECU, injectors, and map sensor would allow a higher rpm limit and more aggressive timing so it can make more power.

    68+ is a tall order to fill though.
