Are you trimming it out?
you should rev them 28's to 6000 with that hp, buddy's 500efi boat does 72&5200 you either are not trimming or engines are not even close to the hp, what are specs on engines? my 91 Konrad gun with 600's and 28's did 72@5100 (needed 26's) saw 75@5300 with those |
Got any uncorrected Dyno numbers?
What is your exhaust setup compared to the Dyno? 750hp is a stout a 555. Big cam and good exhaust required |
