    So we will see Sat

    Im getting sent to me a 137mm supercharger and will be putting it on
    my stock(except for flame arrestor removal) T-X ski.

    What is the consensus on what to expect seeing everything is untouched

    Anyway you could put a 4" intake on your ski. The stock air intake is choking the X- charger, it can be only worst with the ET137. Be prepared to repitch your prop.

    Most people running the et 137 are using bigger injectors along with a rrfpr, but riva says their x wheel only requires injectors

    just food for thought, if you look at Riva's recommendation on install their Xsc upgrade, they are showing 50 psi injectors for both stock ecu and riva ecu.
    I just thought i would pass that info on.

    Good Luck with your test!
