    with that ecu and injector setup you should be running the Riva X SC upgrade kit.

    You don't need more parts!! The parts you have are good for 80 MPH!! Less pitch and a 81mm ring...ding..ding..ding. Proper pitch is everything!!

    How about those pictures?

    Hold on!!!! What's the rev limit on the X model Riva ECU? If it's 8650 like the other Riva ECU, that's where your speed is. Your loosing several pounds of boost..

    and what do you think about rotax racing supercharger impeller for 854$ or sea-doo x charger pro series for 679$?

    what is better? how is it efficient? and when will it damage my engine???))

    Skatsuba:I would recommend a drop in 137 wheel with spacer for only $600. It will give you 2lbs of boost over stock s/c. Also - watch any ring size smaller than 83 on the x boats. They can get loaded up above 77 or so. Plus you need to pitch for 8550 or so to get max boost out of that ecu.

    Another tip: take a look inside your intercooler. The side leading from the s/c. Mine had terrible oil buildup in it. It robbed me of 200 rpm and a solid 2mph!!!!!! Just remove i/c and let soak with gas. Reason? The s/c shaft oiler. The extra oil to cool clutch is blowing by the o-rings in your s/c and clogging up your i/c. I have run for 85 hours with a little j/b weld sealing up the oil hole. Just my .02

    Good luck.

    Also - you s/b running a 4" air intake and not 3". And you should pull the restrictive manifold screen inside the intake manifold.
