    RR high boost wheel???

    Hey guys what are you running as far as props and nozzles.

    I have a 4in intake
    IC
    RR ECU
    RR hboost wheel w/ 42's
    and have the skat adjustable nozzle.

    I have a 15-20 and need to know what ring I should use and keep my RPM's at.
    Still stock valve train... Until MB III.. Jerry?????

    Or should I get the new Skat Riva 3 BLAD?

    81 mm and pitch as necessary.

    The new Riva 15/19 with 81mm ring would be my first choice though.

    The valvetrain upgrade is very easy to install with their tool. You are welcome to borrow my tool.

    You could remove the head and install the Rotax Racing lightweight retainers and shims.

    Yea, does it produce any speed gains or just acceleration?

    It will add a couple hundred RPM's so yes, it produces speed increases as well as acceleration.
