    Prop for RXP with X-Charger?

    I have just picked up an X-Charger for my RXP and am trying to figure out whether to go with a 14/19 or 15/20 prop. I currently have a stock prop and have filled the rideplate holes and put on the Riva grate with a modified R&D grate girdle. The intercooler and air intake are stock for now, but I am planning on adding the 4" Fizzle air intake kit and 42# injectors in about 6 months once I have saved up a little more money. I'm not planning on changing out the intercooler. I know I am going to need a new prop in order to run the X-charger because I am already up the the rev limiter before I add the new charger. Would it be better to get a 14/19 and repitch to hit 8150 once I add the new intake in 6 months or should I just start with the 15/20? I just don't want to be buying another new prop in 6 months because I either didn't buy enough prop or bought too much.

    Go with the 15/20, it should be close and is a better prop to start with if it needs repitching.

    +1 15/20 will be better all around.

    Will just the X-Charger be enough to turn the 15/20 on an otherwise stock RXP? I'm more concerned with accelleration than top speed.

    I have both the 14/19 and 15/20 with mods in my sig and for me the 14/19 is much better out of the hole and mid and is what I use a majority of the time when the weather temp gets above 85.

    if you want more acceleration with only 1mph less top speed than a 4 blade and are only running an X charger with stock IC then the 13/18 skat 3 blade is the one you want. Go with a 4" air intake & you'll be happy..
