    Question Impeller/propeller question??

    Ok I just got most of the Level 2 Riva parts on my RXP (I decided the supercharger impeller and thermostat can wait till winter) anyway what is the stock RXP Impeller pitch? Right now I'm running a 14/19 and should install the 15/20 but I hate to have to take the housing off again at least untill a rainy or windy day. What am I giving up by running the 14/19 vs the 15/20? Should I just do the change out? Help me here
    Thanks,
    Mike

    It will depend on your RPMs that you are turning now.If you are on the limiter it could help but if not it would probably pull your RPMs down to much and you would probably have to depitch anyway.Post your speed and RPMs and we can see where to go from there.

    I know its a dream meter but I'm a street rodder since my very early teens and well that term has just stuck.

    You could take about one mil. out of pitch to get the 100 RPMs back but you are not ready for the 15/20 yet. I think I would just leave it as is for now until you do the additional mods.
