once you get that prop to hook up you will kiss your drive good bye.

Your not going to blow that drive up. It's a pretty light boat
your fine i had alot more power with a stock bravo and lasted a long time. I 'm guessing it is a revolution 4 blade and if that is the case it is bigger than a 25 more like a 26.5 or so.A bravo one is alittle smaller than advertised but your prop is alittle more. So your slip is not as high as you think. It's more like 13or so at 6 grand if that is the correct speed you are doing.If your motor makes power to 6400 why would you not hold it wide open to see what it's got. If it did it on the dyno and danny built it that way then why not spin it that high.I would try a 28 bravo 0ne that might be the ticket if what
you said is correct

And another thing 6400 stock crank stock rods I don't know how long that will last. This is not raceway park.I would see where it made the most torque and go from there.Just my 2 cents.

Not me I got a blown up junker now. I might be getting a stock 454 for now but it still will be a billion mph boat so look out all :lolhit:

Eric i'll give you one of my 177 blowers and will put the small pulleys on it and see what happens.lol

thanks guys for all the info. i would like to try a 28p bravo I and a 29p mirage plus b/c i herd the older fountains may work better with a 3blade? i made peak torque at 5100-5300 645tq 650hp. at 6300-6400 700hp 585tq. at 6000 692hp 605tq. so by playing it safe at 6k im only down 8hp but up 20tq. balanced and polished stock forged gm crank with scat forged h-beam rods so i think im good to go. we built a 510 with good hp and a little less torque b/c the boat isnt that heavy and i didnt want to have problems with the drive. 700hp in basically a 24footer on the barnegat = not running 6k that often.

Any updates? Seems like the smack talking died an untimely death. Not that I have been out all that much but I have yet to see any singles TEARING up the bay. I did see a Phantom a week or so ago that I have not seen in the area. He was looking for a run but I had my 5 and 8 yr olds on the boat so thats a no go.

Yeah I agree on that....What was the speeds of that killer lol.Im sure he foundout what it is like to run 80 or so in a 24 ft bottom.........

How bout youre buddy crapr6? Is his boat blue? I saw an all/mostly blue excalibur coming out past Drum Point Marina a couple weeks ago when I was fueling up.

Heard about that boat from Wazzup race engines..I have no idea who owns that boat...
