Impeller basics

[FLEA DIDDY]

I need some input on impeller basics. I'm building a 557" BBF for my sleekcraft aristocrat tunnel hull. What warrents makeing a change to a different cut impeller. Pump has a A-cut impeller, shoe, wedge, rideplate, loader and a bowl stuffer and of coarse a place diverter. My mill will have a T/R, 2 750's, aluminum SCJ heads (John K) and a 200 shot of n2o. Thanx

I'd say you're getting the cart in front of the horse. Put the motor together, put it in, run it to see what it does and then come back with results and re-ask the question. It's possible you may not have to even change it.
