    Most OEM impellers are rated at around 400 to 450 hp , After market aluminums to right at 500 , Your probably a candidate for a Bronze or Stainless if you can see it in your budjet , Tom

    in the first post it says you want to make 500hp what rpm you want to run 4700? if so why run on the edge when you can get a known good product

    Thumbs up mag bronze

    mag bronze start big on cut and work your way down i would go with a aggressor impeller just remember the flow rate of a aggressor is more than a berkeley so your charts will differ from cut to cut

    on the bronze or stainless most all are cast to the largest size and then cut to the application. the aa that impatient has could be easily adapted to your situation, and agreeing with pro mod get a larger one and cut to your use, i always state it is a lot easier to make them smaller that to cut them bigger, if you get one to small you will have to buy another, go large then cut

    we went too small to begin with, now we're heading towards a aaa mag bronze aggressor
