Mine is old Bravos 1.5 drives. Engines are .060 over 454's with B&M 250 Blowers @ about 5lbs boost. Never dynoed, but I'm thinking 530 to 550hp???

I was running 28 four blades I just put 30s on and like them better

what rpm differance between the 28 and 30 are you seeing?and what kind of power are you running?

Gonna be a johnny come lately, but any advice would be helpful.
looking for the best prop for top end, i understand i will probably lose a good deal of hole shot, but i figure thats ok.
running an 88 bullet, 454's bored .30 over, bravo 1's, running 5100 rpm, with 3 blade props [honestly i dont know the pitch]
