    Impeller question

    Gathering up parts for my build...

    Was wondering if anybody had any suggestions on impellers..

    Its a 2001 GPR with racerrobs old Kerry engine.. 87mm, factory pipes, buckshots, I am going to pull a little compression out of it. It has the stock pump for now. I want this to rip out of the hole...

    Impros DF14/24.... If anything ya can take a little out the trailing edges but that should get ya really close.Impros will bend & size it to 24 then if ya pull a little out it will be ok instead of adding causing rub.

    what prop was racerrob running with it? What compression are you going to run?
    If you are running stock pump that means no Df so....

    If it is an 01 then I assume you still have the original pump, If this is the case find a Nujet 6.5 modified by Island

    Stock pump right now. If I change pumps what would be the best one to look for? I'm assuming a skat - not sure on what size, setback etc.
