LB7: Gasket leaks
- Thread starter S Phinney

New Headers and uppipes.
Maybe 1400's max. It is 1k HP and will see 85+ lbs of boost. I don't know what the drive pressure is but I would think around 100 lbs maybe a little less.

It's Rick's headers. I think the flanges are steel and tubing are stainless. It use to be that way anyway. Why would stainless flanges cause the gaskets to do that in that short of usage?
It is amazing that it made the kind of power that it did at 919.3 with those and a wastegate line bursting.
I'd put a straight edge on both flanges.....you can obviously see the blow by on top of the gasket material....something isn't flat or wasn't tight.
Guess that explains the smoke I seen coming out from under the hood on it on the 2nd and 3rd dyno pulls.
Rick those are from each side. I fixed the passenger side drove it and then fixed the drivers side. No you did not send me any coppers to try. I thought about getting with you about them to try. The flanges look straight to me but maybe things are not as good as they seem. If it had not blow out there maybe I could tell if it were leaking between layers but not like it is now with certainty.
That is for certain. The waste gate line burst as well. Dyno guy was telling me that boost only hit forties and I said you sure you were looking st the right gauge? Maybe he was after this.
New gaskets on the way. If that doesn't do it then send everything back including the pedestal so I can check it over here.
Like we talked on the phone I think you might wanna get a drive pressure gauge on it. Since it blew the waste gate line too your drive pressure may be really high. If not at least we can rule that out.

this is why I will be purchasing ricks manifolds when I buy a set :thumb:
I want to ride in the Hennessey when and if I meet him again. I think I earned it
