    Supercharger impeller

    I have been thinking about Kawasaki's and how there are so few additional parts for our skis. It got me to thinking about the Sea Doo aftermarket supercharger impellers, so I went and took a look at the online store. I also saw that these are available for the Yamahas. Is there a reason that this hasn't/can't be done for ours? I am assuming so or it would have been done.

    I don't think I have seen this topic here before, and didn't want to try to search through countless threads that would have had those 2 keyswords in them...


    Thanks for any info you guys may be able to share...just trying to learn.

    The Kawi's use a roots charger instead of a centrifugal one. Roots chargers have rotors, not impellers. No easy upgrade here. The up side is the roots chargers are more efficient at lower rpms.

    you can upgrade pulleys, instead of impellers. kinda like cars, make em spin faster and you get more boost.
