I've tried searching "boost leak test" but found no results.

I was wondering, how do i perform a boost leak test?

 

interesting. I wanna know too.
One way I can think of is to tape a hose to your charge pipe, hook the other end up to the outloet of a shop vac.
Turn it on and check for leaks with a dish soap/water solution around all your couplers.

 

Get a 2.5 inch PVC cap from any hardware store, and drill a hole in the end of it. Glue a bike pump fitting in the hole you just created and make sure you have no leaks.

Use a standard coupler to fit the PVC cap on the hot side of your intercooler. Pump it up with a bike bump. Listen for leaks.
