I have been having a hard time keeping my T04E turbo attached to my 90+ b230 exhaust manifold. This is on an endurance race 745. I run for 8-24 hours at a time.
I have used good copper coated locking exhaust nuts and hardened studs. Exhaust studs have backed several times, once resulting in broken studs in the manifold. I then attempted to safety wire the studs so they did not back out. After two days of racing I can see a gap between the turbo and the manifold. I am running about 13 psi if that makes a difference, at the end of the last race we were down to about 6 psi at the end.
I had the same problem with the studs from turbo to wastegate and wastegate to downpipe. Locking nuts and safety wired studs has stopped the studs from backing out.
Should I just weld the studs to the manifold, is there better locking hardware I can get?
