Boost leak tester question

[kwimberly]

I just built the boost leak tester as described by Martini on a4mods.com. I have a small pancake tank air compressor - the kind usually used for inflating tires and stuff. In Martini's instructions, he talks about charging the system to 10-12 psi. I can't really do that with my tank - it's either on or off. If I couple it onto the tester and then turn it on until it gets to 10-12 psi, then I should be ok, right? Don't professional compressors let you send the air out all at once, whereas mine will be "filling" the engine's vac/boost system as it compresses air?

My pancake compressor has a gauge on it, I would think most do... If not, buy an external gauge...How do you know how much pressure it's set for?

I would think if you put more than 30 plus PSI then the hoses are not rated for pressure that high and you'll start blowing clamps, hoses, and etc.

It has a gauge - I guess I was just wondering about the unit compressing as the hose was attached to the tester vs. charging the compressor and then blowing the air in in a second step. I got some PM's on it - think I'm all set now. Just waiting for the JB Weld to dry!

let me know how it goes buddy, im waiting till 2moro to get mine smoke tested, greatest machine ever made cuz i cannot find the leak.

I hooked up an inline valve on the air hose. Worked great.

i added a second connection (first connection is the air valve to connect the compressor to) on the tester i built (a barbed nipple) that i then connected a foot of boost hose to and a 0/60PSI gauge too, works great because i can see what the system is pressurized at. i'll get a photo later today if i remember to.
