    Need help with impeller

    I have an 06 rxt with intake, blow off valve, free flow exhaust, pump wedge, intake grate, and supercharger impeller. I am thinking about getting Rotax Racing 42# injectors and i am wondering what impeller to run?

    Larry said it was too tall for his ski, even tweaked -2mm

    Not only do you need an upgraded supercharger, but I'm certain you'd need an external intercooler to turn a 15/20 (unless you went all the way up to a Rude SC, of course)

    I am thinking about getting Rotax Racing 42# injectors...
    Why? They'll hurt performance if you don't need them, and you don't need them with just an upgraded SC wheel. Intake + sc wheel + external IC = 42lb injectors. Any two of those choices and you can stick with the stock 38 pounders.
