    NEW ROTAX RACING SC Impeller> COMING SOON

    In about three weeks Rotax Racing will release their new supercharger impeller. Dyno testing is done and the results are fantastic.

    Features:

    - Lighter than stock = easier clutch life
    - Almost 2 psi more boost than the stock unit!
    - Fits in stock housing. no modification required.
    - Adds 15 hp to a completely stock engine...even more on modified engines
    - Compatible with RR ecu equipped machines( ported heads require larger injectors)
    - Impeller and injectors available through me or Jerry's online store.
    - No firm price yet but approx $450~475. injectors $107.60 ea

    This chart shows the boost pressure during dyno runs on a completely stock engine.

    Where does this bring the combined compression ratio? How safe is it? I heard earlier today...11.7 lbs?

    2 psi equals 1 cr ratio.

    I will give you a hint....The vortec impeller on the dyno produces 2hp...
    This one is producing 15hp..
