How-To: New/Easy Boost Leak Tester - SRT Forums

CJsStocker · 03-24-2009, 05:54 PM

Well, there is nothing wrong with the old method but i wanted to try something which is cheaper and easier to do.

1. GO to home depot and buy a 2" qwik cap, found in the plumbing center, its rubber. Also while there, buy a valve stem or another way which you'll enter the air into the system. And lastly buy a construction grade silicone, i had lots of NP-1 laying around so i used those.

2.Now you are going to make a hole in the center of the cap just enough to fit the valve stem, etc.

3.Place the stem at an angle so you have enough room to connect air to it without much hassle.

4.Apply the silicone to the both sides of the cap, keep in mind the inlet of the turbo so keep the inner circle free of silicone.

5.Wait for silicone to dry(a day), then test fit the tester to make sure nothing binds, if it checks out ok you are ready to test for leaks.

I used tan colored silicone because thats all i had but not like that it matters much.

orooso · 03-24-2009, 11:57 PM

if you use the cheap rubber tire nipples, they pop in from behind and wont need sealant, any you can easily remove the compressor hose

you need to cap the opening on the drivers side of the valve cover and the venturi line if you still have it, then pump air into the system then listen for leaks.

when i test fitted before i put the silicone on, i had to put it at an angle because my hose would touch the brake reservoir, but yea the tire valves also work great as long as they are not angled.

lol, thats almost how i made mine but i used 3" end cap pvc with a quick disconnect (just drilled a hole and threaded it in) for the compressor like you did.

be very careful, i do my boost leak off the turbo elbow and i didnt tighten the clamp hard enough

....let me tell ya that cap popped off with a huge boom and almost took my head off

....i had to change my shorts

HAHAHA I could so picture this!! OMG i bet that shit was LOUD! I had a nitrous line that i was disconnecting once that had nitrous in it. I loosened the line let it sit for a bit then disconnected it when i thought it was empty!! That focker popped off and scared the hell out of me.

How many psi should you pressurize it to?

CJsStocker · 03-27-2009, 08:58 PM

depends on how much you are normally running.

Im running about 16-17 so i take it up to 19-20, so pressurize it a little more then what you are running. And MAKE SURE to tighten the clamps very well or even use two.
