    What needed with a s/c wheel

    I have a stock rxp right now and looking at getting a new s/c wheel when i pull it off for the upgraded washers. I have some 42lbs injectors, will i need them with just a new s/c wheel? and what other things are needed at the same time?

    yellow, you are far from needing aftermarket injectors with just a Riva Vortec SC wheel.

    alright sounds good I hope it makes a noticable difference. What is the estimated hp gain from the riva/vortec wheel?

    you wont notice any difference in top speed, you notice a little more mid range pull. the stage 2 riva/vortech impeller is rated a 2hp.

    is it really worth getting if it only makes 2hp? or should i spend the extra money on the RR wheel thats 14hp

    It's definitely worth spending the extra money. BIG DIFFERNCE between Rotax SC and stage 2 Riva SC. If you have the money the Riva stage 3 SC is the best bang for the buck but if you have to choose between the stage TWO sc and the Rotax definitely go with the Rotax.

    I went RR and think I made the right choice. It cost a little more but you wont regret it.
