    riva stage one and stage 2 impeller question

    I plan on running the stage one with a rotax racing exhaust this summer. My question is, if next year I hope to upgrade to the stage 2. Should I get the stage one impeller or not worry about it?? OR will the stage 2 impeller work with those mods?? I Figure the impeller has alot to do with the acceleration and top speed in both kits. what would the stock impeller do with the stage one set up and rr exhaust?

    thanks!

    Run the 14/19 until you install an external intercooler. At that point you will want to run the 15/20.

    The stock prop will also work with the Stage 1 components, but you will be giving up alot of acceleration and some top speed.

    are these pitched properly for my set up? I've read that you have pitched some for better performance? If thats the case could you repitch it before you send it out to me?

    I advise you run the prop first and then i will pitch it accordingly.
