Jeffkopec - Is my top speed realistic?

Is that with 1.5 gears? If so, your slip numbers are pretty high, 23%, and 19%.

Yes it is.

Sounds like you are leaving some speed on the table. You should be able to get your slip below 15%. Even at 15% you would be +4 MPH.

Update on the motor build. I don't have the build sheet in front of me but a quick synopsis....

Bandit Racing
Gen V 454 bored .30 (460cu)
Dyno- 602 hp / 570tq
6000rpm

No idea what my top end is going to be but I'm sure it will be significantly higher than my 1997 454mag with 550hrs. Going to start with a 24 bravo for testing. All new livorsi gauges, mayfair steering, full cover and detailing. Can't wait til they call me for the dial in time,

good luck with the testing, now comes all the fun

I have a notched 300 and i run a 30p Bravo 1,is there that much difference between a straight hull and a notched hull?

About 5mph topend. What motor/hp are you
Running? Top speed?

I have a 496HO with a 3.5 Procharger 580hp.Speedo shows 80.
