Boost leaks

[JD Dave]

I'm having a hard time getting more then 50 psi combined out of my twins. The big turbo puts out around 25 psi. I pressurized the system and found my y bridge was leaking really bad so I fixed that. Looks as though I picked up another 5 psi but I still have a couple more leaks. Do you guys worry about trying to seal turbo housings and if so how do you do it?

You need to make sure the surfaces are completely clean and flat. You should not have leaks at the housings.

From what I can tell everything is smooth and clean. The big turbo doesn't really leak but the s 475 does. Nathan told me to use high temp silicone but that seems like a real PITA. I'll check them again to make sure there smooth.
