    gp 1300r 06 impeller

    Hello and nice greetings from germany!

    I have a 2006 gpr 1300 with:

    r&d 1200/1300 intake grate
    r&d ride plate
    r&d d-plate
    pump seal kit(self made)

    I`m reading and reading but i cant find the right impeller for my ski.
    I`m searching an impeller for higher top speed which doesnt reduce my acceleration.

    You can't just install a different impeller and expect more speed. You have to operate in the correct WOT range. A larger pitch impeller will reduce your WOT RPM, therefore you have to mod your engine to be able to turn the higher pitch at correct RPM. A solas dynafly 14/20 may get you slightly more speed, but will be stock pitch for your ski. Its also a nice upgrade from the stock impeller.

    In general, I would be worried you may not be able to turn a DF 14/20 with your current set-up. That being the case, you could always try it out and have it repitched if it doesn't work out.

    You could also take the safe route and go Concord 13/19. You definitely won't lose any acceleration that way, but I don't know if you'll see that much in a top speed increase.

    If it were me, I would gamble on the DF 14/20 knowing I may need to have it fine tuned to work with my set-up.

    Better yet, if you struggle to turn it, upgrade other things so you can!

    That is a HO pump...it has to have the dynafly. 14/20 is stock pitch for that ski. Start there.
