Re: more 272 mods
Sorry to hear about the procharger.
Just before the last PR a friends procharger did the same. The bits went into the motor. He took it all apart and reckons that the lubrication channel on the rotor had blocked (and that it is a design weakness of the pc) and run the bearing dry with the inevitable results!
Hope you are back on the water soon.
Stories like his and yours delay my plans to put a Whipple kit on my 525 and thus save it from the eventual "death by blower" syndrome.
But sometimes the need for speed is stronger.
Good luck
Stephen

Nicely done. I did the same thing and ran the hoses into the box. Did you get the supercharger fixed? When you are all straightened out how about fitting my dyno on it?

Re: more 272 mods
Boat is definately slower so far with the ext box. Did several wfo runs this weekend using 30 pitch prop,boat will usually run 89mph and some change with full load,best run was 87.5 at same rpm's it used to run 89.5mph. Boat definately porpoises if you try to cruise between 2800 rpm's and 3800. Lots of tab will stop it but slows boat down. Boat also cavitates prop when it hits 3000 rpm's,starting to see burn marks on it even. Am going to try a 1 inch drive spacer maybe to see what happens. If it brings speed back to what it ran originally before box and no more than it will be coming back off this winter.It looks really cool,getting alot of comments but I didn't install it for bling factor. So overall it hurt general ride of boat with the porpoising and created new drivability issues.I will post any other things I gain from drive spacer if I buy one,Smitty
