GPM

It's nice to see another procharger owner, looks like you should be able to break some drives.

GPM

I'm very happy with my procharger, my xr isn't I get 6 to 8 hours out of a set of gears.

GPM - Where are the failures occuring - upper cap? Catching air or just brute power busting things up?

GPM

to much torque, pealing the faces off the lower gears.

GPM

are you running a stock intercooler, as far as water supply?

AIR TIME

what size boat and weight is it and I'm looking at a P/G set upfor my motor 509 647hp at 5900 627tqat4700rpm I was told to go with a m3 or m4 my boat is 4000lbs

GPM

26, weighs 4000, the M 3 would be good for the 509, M4 if you ever plan to go to a 540.

GPM

Scarab, don't want to leave you out of your thread, I think you're going to surprise the whipple and roots guys. Looks good to me.

Scarab28

It's going into a 28' Scarab - 5000 lbs.
I agree that an M3 or M4 is a better fit for the 540.
Now to start working on the external steering.
