Thread: gtir part throttle problem

what wouldn't hold psi? your turbo piping or the adapter you made for the leak tester? A proper seal is when you don't hear anything.

Well you def need to fix all your leaks first because that is very important and can change everything.

Sorry aabout that its because my compressor wasn't working so I used a tire pump wasn't enough power to be able to hear any leaks I repaired the compressor and tried again I heard some leaks one was by the intercooler fixed it and other was right off the turbo fixed it I only have four couplers total my inter cooler piping is welded so one off intake mani one off turbo and the two on the intercooler after all that I performed the test again and it seems as if its leaking right off the turbo housing where the bolts are to clock it I loosened them took off the snail I'm going to reinstall it maybe it wasn't on flush any ideas on that

I'm having a similar issue. Try some RTV.

You can also try to figure out a way to pressurize just the turbo to make sure your fix worked so you don't have to put the turbo back on the car to test for the leak on the housing. In other words, you can put the tester right on the compressor housing inlet and then block off a pipe from the outlet so you just pressurize the turbo.

Have you tried to apply rtv on yours its real easy to remove the housing on mine and do you think that housing leak would explain my vacumm only reading 9-10 in.hg on my gauge? Thanks for the input guys

Ok so I sealed up the housing with copper rtv leak is gone did pressure test no more leaks but my boost gauge is still reading 9-!0 at idle on vacumm side odd. Hope its not a compression problem don't want to drop all that cash in parts to build it just yet has anyone else had low vaccumm readings on a gtir with upgrade turbo imma take it to irwindale today in a bit see how it does last week I ran a 7.7 with those two huge leaks and the car did feel a little weak so it has to do better

Ya, I put RTV on the housing but it's leaking from it seems like the backplate adapter and CHRA now which makes me think it's the big retaining clip. We're going to take it back off and fix it for sure.
