All stock Capo71, I was seeing around 67 gps, and best was around 69 on 1-2' chop 1/2 tank fuel. won't know how fast with 650 HP till spring

Same here about. I love this boat is chop. What did the set up run ya $$$? got any pics? send em to me at [email protected] i have a few of my boat but can't post them here

You know we have our supercharger system available for the 496 HO and we recal the ECU for the supercharged motor. We run 6lbs. of boost and make 625-640hp, 700lbs. of torque.

Thanks,
Dustin

I have been told that no matter what supercharger I put on, Plan on blowing my drive out real soon stock bravo1 =500 hp all these blowers = 625+

The drive problem is sooooo over exagerated, the stock drive will live in most applications with this power level, especially for normal boaters. Anybody can break something, a little caution, routine service, the drive will live in most cases. I run the living crap out of them and I've only broke one myself, and I've worked, tested, abused as many drives as anybody. I still have some of our original customers running stock drives with their original 502 mag SC kits.

Thanks,
Dustin

I highly recommend the wipple over the procharger.
I just installed one on my 502 efi and so far I love it. I had some installation issues (from previous owner mucking around with fuel system) that were NOT Whipples fault. Once those were cured-Viola! Instant horsepower
If I had 500 efi's I would be all over the polished top unit!!

I'm with Dustin, It's all in how you use it. My drive has over 224 hrs at 650 HP.

Hey Dustin, whats with the bicycle air pump attached to the heat exchanger???

Kanookstr, thats the hand pump to drain the engine for winter, comes on there stock. Also handy for puppet ballons and beach balls

Dustin

Ahhh, I did think it was kinda small for a back up whipple charger....

Dustin, are yours available now for retail?....
