383 LT4 with paxton supercharger problems
Ok here is the deal. My father bought a Corvette that has a LT4 thats now a 383 and setup to run a paxton supercharger. When we got it, the charger wasn't all hooked up and there was no instructions. Although we was told that it had been run on the motor before. After getting it hooked up, it started and ran fine, but after geting on it a little discovered oil leaks. 1st up was the dipstick and it was resealed. 2nd was the rear seal so it and the oilpan was resealed just for safety and to check the bottom end. After all this we got it together it blew the rear of the intake out and spits oil out if you get on it just a little. It was taken off, new gaskets, the ends cleaned and new silicone was installed. Everything was fine again until he stepped into it and the rear of the intake again blew out. 3rd time and again it blew. What hoses need to be took off, added or what? I'm not up to date on superchargers, but blowing the seals out tells me there is too much pressure in the motor. Compression is around 140 across the board, has eagle bottom end and JE pistons. Does anyone have an answer to where we are getting all the internal pressure from and how to fix it? Thanks for any help[/b]
