in 2022 I think I'm at the point where I can say that if you need more than a composite will do, you also need a filled block. Also when you are playing around at very high boost like 49, you can't let it hit the revlimit or do things like that. Does all sort of wierd things to combustion events. The automatics require a different approach to tuning than a 5 speed.
Last thing, old heads get soft and they don't retain a head gasket well. Sometimes it's just best to goodbye to an old friend. xzy2011009 studs that you torque to 6000ft*lbs and pull the block through the head won't help if the head is soft and flexes between the studs.

Why do you need 49psi? Trying to go 7's? Why don't you start out soft and make it work right. With a 76 on it, that thing should go bottom 9's at 25psi. Parts are really getting too hard to come by to ruin on these hail mary bs passes.Bringing back from the dead but how much boost are you running if I may ask? I'm running a 76mm with L19's and steel o-rings in the block.
Was just at the track and running 49 pounds of boost but coolant started spraying from the side of the block. Don't believe it was the gaskets fault though, but old stretched out, not properly handled L19's that were the problem. So ordered new ones. Still makes me wonder how far I can push it though. Wondering if this setup can handle 60-70 pounds of boost. Guess I'll find out but just wondering what you were doing. Thanks!
