    prop for basic mods? 08 rxp

    Right now the only mods i have are a 3" intake and a riva intake grate and i have a rear exit exhaust waiting to go on when the snow melts. Im looking to add a prop and either a external IC or a SC wheel. Should i get a 14/19 or a 15/20? im not looking to do much after that. I dont race at all just a weekend toy.

    If it helps i live in upstate NY its usually *80-*90 with high humidity. Last time i had it out my rpms were at 8050-8100 at 69.5mph gps

    If you do an ET charger wheel, and injectors to go with it, you can run the 15/20 and it will run great. You don't need to change the intercooler. The wheel and injectors will make a big difference. The 4" Kanaflex is a much better air intake and costs very little.

    Will a 127 require a rrfpr? And will the 15/20 hurt performance without the 127?

    No rrfpr 127 and 42s but an ex IC would greatly help out the ski

    127
    ex IC
    42 injector
    15/20 prop 2mm pitched

    will be a 74-78 mph ski pending on hull setup or rideplate

    Thanks guys. I didnt get a clear answer on my prop question. Will the 15/20 hurt performance with out a 127? I wont be buying/installing everything at once and the prop is going on first.

    With the stock charger, I would go 14/19. The 15/20 will be to much prop I think.

    Thats what i was thinking but will it lower my top speed untill i get a 127? I dont want to buy 2 props or have one sitting in a box for a few months.
