    Supercharger difference 06 vs 12 rxp

    I have a chance to install a 12 rxp supercharger in my 06 rxp. Is that worth the upgrade? If so what else do I need? Thank you.

    Currently I have a green wheel in my sc

    also suggest a wide band 02 to tune it and a RRFPR.

    and a bigger prop. 15/20 or 15/21

    Sorry. Yes rxpx, is the upgrade worth it since I currently run the green wheel on my sc?

    Also, I have the large fiZzle ic, 15-20R solis, riva stage 1 and straight through hull exhaust.

    sorry missed you have a rxp. 15/21 probably to small for that with x charger.

    I think its 3-5 pounds of boost more with x charger vs green wheel.

    Where did you pull 5psi from??

    You might see an extra 2psi, but the x-charger is 137mm, vs the 127mm greenwheel.
