Whipple on a 500EFI in a 29 fountain
 

Hi guy's, I bought my first fountain boat at the beginning of the summer. Its a 2001 29 lightning. I put on around 100 hours on it so far. I was thinking about installing a whipple supercharger on it, wich from what I read should give me around 725/750 hp?? The engine have around 200 hours on it and it's hooked up on a bravo 1 with a 26 pitch 4 blade, I'm running 73-75 right now. I did hit 77 once with the current, 2 people and half a tank. That's with GPS. Now how fast can I expect to go and will the drive hold that power? I do baby it every time I'm getting on plane.

With that much power your Bravo 1 outdrive is not going to last long. If I were you I'd upgrade to something like a IMCO SCX or at a minimum IMCO SC. Bravo 1's aren't designed to handle that much power. Is far as how fast I'm guess at least 90 or so but again guessing. Maybe faster.

Mine is also an 01 with a 500efi. You might want to double check into the drive. Mine doesn't say "xr" on the drive, but it is an xr. You will want to reference the sn#. I was also at first under the impression my drive was a bravo 1 with a 1.25 inch lower prop shaft. This past summer I had to replace my lower and found out my drive is an "xr". Also, I have similar questions to the OP. I'm looking at freshening my 500 in the next couple of years and possibly adding a whipple. I guess my goal would be to run 80-82 mph. I always believed in" if you want to go faster, you buy bigger/ faster, which would put me into the twins game. At this stage budget plays the biggest role and twins are not in my future, but a paid for 29 single is, and I've also read that a whipple on a blue motor is very reliable. Anybody have this setup? Experiences?

I was told that with that motor and drive the safest upgrade and the most reliable is going with pro chargers instead of whipples they r sapost to be easer on the motor and drive. just what some one told me because I was thinking about doing mine eventually.
