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

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:p

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 :D 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:D
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???:rolleyes:

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

Dustin

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

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