    A good look at the new Rotax Racing supercharger imepeller

    Here are some side by side pictures of the new impeller VS. stock.

    Amazing how much shorter the RR impeller is.

    One very good thing about the new impeller is it is 65 grams lighter than the stock one. This will make it MUCH easier on the clutch.

    I just talked to sandrock who just got off the water with his RR impeller and he said it's a night and day difference over his old Riva/Vortech impeller.

    Hopefully i will have results soon with this impeller on Carey's ski with stock ECU and RR 42# injectors.

    What I noticed first is that there are no half moon cuts for the balance of the blade. So in my opinion it is made to better speck than the Riva.

    How does that mesh up with the outer SC housing being that much shorter?? Almost looks like it would have a gap, or would need some kind of special spacer??

    No spacer needed and yes there is a gap. It will let more air in that way

    My rear intake will be screaming with that thing!!!
    I did a drive by on the lake beach and my wife told me people were asking if I had a radio blaring because my SC was whinning.

    That is going to be louder than my exhaust. Can't wait
