    Project XXX almost complete

    i'm puttin the final touches on what I've been calling "project XXX" Riva finally came out with the athena pro-series ECU for the 2012 RXP-X260 and with that i am able to finish off the full Stage 4 kit for the ski. since i live in california its just about getting into ski season for me, with a wet-suit, so im workin hard to get this thing finished for the summer. I'll have speeds posted when i get the GPS speedo, but the kit claims mid-high 80's, while pushin 14.5 lbs of boost from the XXX supercharger at 8500-8800rpm

    High 80's with an xxx charger? Im not trying to be a hater here but that's gonna be a tough number to hit with what you are running. The factory speedo is off 3 mph or so, maybe riva claims that's what the dash will read, still gonna be hard to even come close to 85

    Stage 4 for RXPX 2012 Riva claims 80-81 MPH, I do not think you will reach 85 unless you add an ET race or Rude 3 with a stand alone management ECU spinning over 8800 RPM.

    9k Plus RPMS and a good hull setup should yield 85+ no problems with that charger.

    That CRT ski is an older rxp hull. At least the thread I found was. A member with a motec, 3rude on a new rxp is running 82 ish. I fought a boost leak all summer but even at 16-17 psi boost with an et race I still never broke 85

    Carlito at CRT did have much more done than just a turbo setup which I won't get in details.
