[QUOTE="footlong70, post: 1281695, member: 8456"] Boost leak testing kit. Which is essentially, a handful of different size round plugs (3"up to 4" or 5" in 1/4" or 1/2" increments), different size boots with clamps, a regulator, gauge, valve, and a quick connect to run to your shop compressor. They actually aren't that expensive. I picked one up on sale locally for 90 bucks. But they are pretty simple to build if you can lay a bead. All you gotta do is put the plug end right at the compressor inlet where your cold air intake attached to the lp turbo using a boot and t-clamps. Then slowly add pressure. You will be able to do a total pressure test of the intake system to the valves/pistons. A small amount of air will blow by the piston rings (so you won't be able to hold the pressure) but you should still easily be able to bring the pressure up to 15-20psi. I usually test to 30-35psi. Just have to be careful not to over do it while keeping limbs clear because you can spin the motor over with too much pressure. Big leaks are easy to find, and then small leaks can be found pretty quickly with some soapy water. Personally, I always pressure test the system now after a build or after pulling any significant plumbing. I've seen so many aftermarket, brand new parts leaking. Particularly intake manifolds.
