Testing for boost leaks A very simple and accurate method to finding boost leaks. I was having problems after just finishing my turbo kit holding boost and wasnt sure where the problem was. I made a quick video showing one way of pressurizing the system and using soapy water to find the leaks.
I had a couple significant areas needing addressing, but this is a good way to find the smallest of leaks or in my case large ones.
Hope it may help one or two people.

So maybe I'm not thinking about this correctly, but aren't some of the exhaust valves open? I guess that's why you use the regulator set to 5psi, so that it's constantly pushing air to the system and out the exhaust.
Also make sure you turn up the pressure to at least whatever boost you're getting up to. I tested my cold pipes and there were no leaks at 5psi, but many at 15psi. I didn't clamp down the couplers enough.

exactly, when the exhaust valves are open the intake valves are not and vise versa, this allows enough pressure to build in the system to find the leaks. Yes there may be some leaking through out the engine but its enough pressure to do what you need to do and verify problem areas.
one would venture to say that thing should make a good bit more power once you get her plugged up. Great Idea. I am going to make one of these for my procharger. I thought about using a snow foam gun on my engine bay.
I'm bumping this thread because I think it's a good reference for people who, like myself, put a setup together and never test it to see that it's actually holding air like it should be.
I'm picking up one of these today:

That I'll thread a hose coupler into the end, then pressurize my setup to see if I have any leaks.

I built a quick and dirty setup using parts from Home Depot. When I built my cold side for the FMIC, I used a regulator to crank the pressure to test it at various levels. I didn't pressurize the engine but simply removed and capped the charge pipe to the throttle body. Everything was solid up to 25psi.

i test each pipe i weld individually with rubber caps from home depo. if they can hold 15psi for more than 15minutes there. good then i jam them in the car so i dont have to take stuff back apart. but good video for the regular diy

Verdad Gallardo Well, I just tested mine and I have 2 pretty bad leaks, at least I think they are bad. One is at my iat sensor and the other is at the proflo valve. I wanted to change both anyways, so I'll kill two birds with one stone. My IAT is slow as dirt to respond. It doesn't even react to methanol being sprayed on it.
Anyway, here's my video. I set the pressure to 17-18psi and it's pretty loud the leaks. I'm wondering how much boost I'm losing between the two leaks.
