    Riva Stage 3 SC with stock IC & Injectors

    Hey guys I got a buddy that wants to run my old stage 3 charger on his ski and was wondering if he is gonna need 42's with just the stock IC?

    I have ran the S3 , stock injectors, and RRFPR for over
    100 hours now. !! Will need rrfpr or 42's to give enough fuel.
    I don't know though if will run rich with just 42's on idle/low end

    A rrfpr is much more then a set of injectors. If it is between one or the other why not just get the injectors? Most of these skiis are not ridden slow enough to load up on fuel anyways, and hes already wanting to go faster.
    If it were me I would just get an x-charger, 42's and call it a day. Better setup then S3 imho.

    I'm running an X charger and 42's. It's a good trouble free set up.

    What kind of top end speeds are you seeing?


    As for the OP, maildude on this forum was running an s3, piranha IC, and 42's with no problems. No RRFPR and on the stock ECU.

    Keep in mind we ride at 1,100 feet above sea level.

    I have a gen2, XS ic, 42's with no issues. When running the x-charger and external IC you need the 42's w/rrfpr. If you dont have an external IC you dont need the rrfpr.
    The x charger will push more air then an S3

    hes asking about a ski with a stock IC.

    I believe the answer is 42s and no rrfpr.
