    What is the right RPM for a stock 2008 rxp-x 255

    Hi just got a rxp-x 255. 2008 and had her out Saturday and the top speed was 63 and rpm at 7625. Is this what I should expect. Or do I have a problem some were. Like the wear ring or supercharger. Only reason for the question is people are getting up to 8000 rpm and 68 at top speed. I thought is you had a problem in the impeller or wear ring the RPM would go up. Any info would be great. Thanks

    Did it run like mine before you did that. And is that a new impeller or something that people can do to them

    Ok I see its a new impeller, so is there any other things I would have to add to be safe running this impeller. It's saying its for stage 2 rxp-x

    If its a stock ski, a stage 2 impeller is to much prop. You need more power to spin it or go back to a stock prop or pitch.

    I thought so. But I can still get it pitch. So what would I ask for

    Oh what did you do to get yours at 80 mph

    8150, remove the intercooler and clean it out, mine was blocked with a grey sticky gunk, went like a rocket ship once cleaned and 8150 + all day long
