    Riva or R&D RXP 215 supercharger impeller question

    Hello everyone, I have an RXP215 that is completely stock other than having Riva Steel clutch washers installed before they disintegrated and blew my engine up. I'm close to have 100 hours and when I have the Supercharger rebuilt, I was thinking of having either a riva or R & D Supercharger impeller installed to give it a little more ooomph!!! I was just curious as to whether anyone had any suggestions as to which one is better, I looked at the R&D website and they have Impellers that add all the way up to 40 extra Horsepower. Is this a safe and reliable way to get more performance from this ski, since I'm having the Supercharger rebuilt, it seemed like an easy add on. Thank you for any suggestions.

    Riva or R&D RXP 215 supercharger impeller question

    Many would suggest just upgrading to an x charger and 42# injectors. But another option for drop in wheels for the 215 would be an et127 you'd still need 42# injectors

    Or he could find an old S3 wheel and not need any extra fuel. In any event and no matter which he goes for...he'll need a taller prop.

    MarineBoy...I hope you plan on improving your air intake at the same time you upgrade your wheel.

    I'd certainly be up to improving the air intake, any suggestions of what would be the preferred set up. Also, with the Supercharger rebuild kit, is the Seadoo kit the one to go with or is there a kit on here that everyone prefers. I've read alot of people have sent their Supercharger to Jerry on here and is that the kit to have.

    Yes that is the kit to have from the online store. Send it to Jerry and it will be done right. Add mcmaster spring washers and a viton front seal for a bulletproof sc setup
