    SC impeller differences

    What are the differences between the two SC impellers other than price?
    Would be going into a Stage 1+ RXP with more to come in the future.

    I would not buy a first generation Riva vortec. It just isn't worth it.

    Go the RR high boost wheel if you want a good increase with a small price tag.
    You can run it with a stock IC and Stock injecters.

    I never thought the riva wheel was worth anything.. It's basically a stock replacement. I guess the pricetag shows that because it's $399 and the OEM sc wheel is listed at $383. Reinforcing what others have said: don't waste your time, go with the Rotax wheel if your two options are riva s2 wheel and the rotax 'high boost'.
