Here you go.Merry Christmas!

Boost Leak Test Procedure
This section will describe to you in detail, how to perform a boost leak test on your single turbo setup. If you are using a twin turbo setup, an alternate method will be described after this one.


Single Turbo Setups:


Slip BoostLeak Tester over the compressor inlet of your turbo.
Tighten Clamp
Set pressure on air compressor to desired amount of boost. (It would be a good idea to set the pressure on the air compressor to the amount of boost you would like to be running in the car. For example if you are planning to run 30psi, set the compressor to at least 30psi.)
Attach the air hose from the compressor to the quick disconnect fitting on the boost leak tester
At this point you can take the time to listen for air leaking out of the system. The system will be pressurized so any air leaking out should be easily audible. If you are having trouble finding a leak, feel around the general area and feel for air on your hand.
Once you've located the leak, now go through and fix it

 

Me and another had removed all the piping and intercooler to test for a leak. We used PVC caps and a tire valve stem. We used a tire pressure gauge/air chuck to check the pressure and sprayed a soapy solution on the parts to check for bubbles.

That took the turbo and manifold out the equation though.
