Reply With QuoteA imp at 5500 rpm's takes roughly 525 HP, AA imp at 4700 takes roughly 391 HP. Actual speed would depend on hull weight and efficiency, etc.
Can any one tell me about what speed i would be going if i can turn my A impeller 5500rpms what about a AA at 4700 rpms thanks for any help.

Thanks for the reply i have never GPS my boat i was just curious on how fast i was going 78 eliminator sprint A impeller thanks for the info
the universal answer would be not fast enough :wink: :2purples:
no one ever is

On my Taylor, since a 5300RPM "A" registered 72mph, a 5500 RPM "A" would be arround 75 to 78 MPH I believe, ASSuming minimum wear ring blowby. That's an 18', 2,000 lb shallow-V hull. Your results would be different in anything but an identical hull setup.
I've rebuilt my 454 and uprated her to about 400HP from 330 (cam & intake mainly, headers next winter) and keeping the Nitrous that had me at 72. Why, "Not Fast Enough"! I had a FEW lice able to run with me and more than a few ?rop jobs challenging me closely lately. NO MORE! :smile:
