    2004 RXP what prop do I need???

    We have a 2004 RXP. We are putting a greenwheel charger, 42# injectors, 3" Riva power filter, Riva free flow exhaust tube. Is the Solas Concord 15/20R to much for these mods, Or do I run the Solas Concord 14/19R since I dont have an intercooler yet?? I need to order quick so any help would be greatly appreciated.

    I'd say you have a perfect handle on the situation. 14/19r until you go with the intercooler.

    The standard Solas 15/20 (not the R) will work great. And it's cheaper too, around $260.

    The R prop is $269.95 with the greenhulk coupon code and the buyer has the benefit of having an impeller that's been pitch blocked for accuracy

    I have measured regular 15/20's and the blades are all over the place

    I kinda think the 15/20 will be a little bit much for those mods this time of year.

    I had a stock charger, XS IC, and riva rear air intake with extra flow through the grab bar and needed 75 degree temps or cooler and a 83 mm ring just to run a 15/20r depitched 2mm at 8100 rpm. So if you choose a 15/20r with just a 3" riva front intake and a greenwheel I wish you good luck.

    I said NOT the "R".

    Last summer with 73*F water temps and DA of 2300-2500ft I had a rear intake, XS IC, S3 charger, 4tec waterbox, 83mm venturi to spin a 15/20R untouched to 8100 RPM.

    The stage 1 does not come with a SC wheel! That's why I have this question.
