    Impeller selection

    I feel like I've done this many times before...flip me off if you must, but I can't seem to find where the answers were for my old post.


    I have decided to run the following setup:

    2007 RXT
    Riva Stage 1, Rotax Racing Intercooler, X Supercharger, RE Blockoffs



    What size impeller will I need to run this setup?

    Sorry to keep on pesting, but before I wasn't even sure if I was going to be buying the supercharger or not. Now I know for sure the supercharger will be ordered within the week.




    Thanks in advance

    I have a 14/17 on it right now, it's at 8100rpms right now. Are you sure about the 14/19, just looking at your set up, I didn't see an aftermarket supercharger. Riva's S3 wheel has 20-25hp gains from what I hear, and the X supercharger is stronger than that.

    Sorry if I'm being a bit anal, but I live overseas and the cost/waitime to get stuff onto the island is a pain in the ass.
