I have just purchased a 95 powerquest 34 viper with 500 hp's and would like some feed back on a good low cost whipple style supercharger set up for the motors, I am looking for a moderate hp increase that will get the boat up into the mid to high 80 mph range, the boat runs 78 mph now. I was considering the weiand blowers or the whipple set up, but i am not sure since the whipples are $6500 each and the weiands are $2500, what is the big difference ? does anybody have experience with either of the 2 set ups ?

If you have a straight hull, '95 Vyper with stock 500 hp's that runs a legitimate GPS speed of 78 mph, I wouldn't touch the motors. My 99 stepped hull Vyper with 500 EFI's only runs 74 GPS. If you install the superchargers, let me know how the work.

DITTO!!

World's fastest straight hull PQ, for sure!

The motors have some work done to the top end and GPS is at 78 mph. why is there such a bad thing with the porchargers or whipples ? dont the 525 sc's ues a weiand 177 from the factery ?

Yes they do I like mine and would recomend them. There was a set of 177 for sale about a month ago on here somewhere good luck.
