    US RXTX-260 skis are GPS limited to 68 MPH.. No mater what go fast parts you install the ECU will pull the speed back to 68 MPH.. Purchase a Rivas GPS Over Ride Module (250.00) and your speed will increase. I have the same ski. 4" Rear Air, Solas Prop (15/22R) Rivas GPS Over Ride Module and Worx Grate = 74.8 MPH... I'm sure you already know this at 30 hours but you are in Sport Mode right!!! Good Luck...

    We need much more detailed information to help you!

    Are you in Australia? If so, you should have an International "RS" ski and SHOULD be doing 72 mph / 115.8 kph pure stock with 30 hours. Lots of sources for poor performance: boost leaks, impeller issues, grate, pump clogged up, IC clogged, wear ring excessive wear, pump bolts loose, poor fuel, spark plugs, LOTS of potential issues!

    The rpm you report is NORMAL - but your speed is slow for an International ski - normal for a GPS limited North American ECU.

    More FACTS?

    At around 69mph @ 8040rpm i think your ski is running fine.
    When you say you got blitzed, was this from holeshot the whole way through, or just top end? I wouldnt be surprised if you were beaten on the top end, but if they are getting you out of the hole there is something wrong...

    On another subject, have you ever done the oil seals in your supercharger? Im a little concerned at have much oil I had in my blower when fitting the Fizzle.
