Re: 502whipple with bravo 1
 

I drive on the Ohio River.Its hardly ever rough just some tsunamis from the barges.I dont run it hard and i get it on plane easy.I dont push the throttle way down while starting.The boat has a 454 right now and does about 56.This is a very heavy boat which is why i want bigger power. :D

No neither of you can rub me..... But you should buy a lottery ticket if you doubt me. This drive still runs strong and as a matter of fact, I came onto plane today at 81 MPH out of Dana point Ca. for a two hour run. Guess what? The drive once again survived! I did buy a backup last year and have never even had to look at it! My god, if I changed my drive fluid every fifteen hours I would have to change it just about every two weeks!:p

That's what I did, about every two to three weeks and change oil every three to four. I think you are on a great run of luck or are really easy on it. I hope you continue to have the same.
I have had them last 150 hours and as little as 7. Same conditions. Easy out of he hole always in the water I think it is a high spped thing when they give up 85+ and the prop starts to break lose and give up the top end.

What MPH can I expected out of a 26' Sonic with a 496HO whipple charged 5.5psi 660hp on a bravo X ?

What prop do think I should Spin, I am spinning a bravo1 4 blade now at about 5100 rpms with speeds of 66.7 just on the HO.

Re: 502whipple with bravo 1
 

Forgot to add the whole top of the mototr is being redone to better suit the whipple.

Is it realistic to expect low 80's?
I've always heard it was 16-19 hp for every 1 mph gain, I would be adding about 240hp which if the formula is right would mean I should be somewhere in between
79-82 mph range. Is this correct :cool:
