Boost leak test, wont work...

[Jello_Rolls]

I chose to go make a boost leak tester, and thought I did a good job, slipped right onto the turbo and went to go pump it up. When I did, it slowly leaked down from 70psi, which took less then a second to get to 70. It seems that it wasn't going through the plumbing past the turbo, and the boost gauge wasn't reading. I don't know where to start sounds like the only place it was leaking was between the end of the valve to the compressor attachment. I know that there is no way it could jump up to 70psi in a second filling everything single thing. Please help, thank you in advance.

It sounds like a problem with the design of your tester. Post a pic and explain it. We may be able to help you.

I sure hope you didn't subject the intake to 70psi. There are several diaphrams that shouldn't see that kind of pressure. They become overfilled balloons when you do that. You need to use a pressure regulator between the compressor and the leak tester. You want to start out low and work up to just over the max boost pressure you run.

Well the design of the tester is legit and fine (think I can't design a measely thing like that?), air goes passed the valve, and then cups onto the turbo intake, there is nothing that could be incorrect about that. It just seems like it gets trapped into the turbo becuase there is no way it could fill up the volume of anything larger then just the turbo in under a second. It does let air into the turbo because when I take it off and put it against my hand it has pressure, but it is not getting further then the turbo itself. What I am trying to say is when I go to fill it I flick the switch on and off as fast as I can, and pretty much goes to 70, then it slowly decends all the way to 0 in 10 seconds due to the valve leaking to the connector of the pump since I can't pull it off fast enough.

Man whatever you do dont subject your turbo and intake components to 70psi, that will ruin something or blow off your intercooler pipes. 20psi should be enough to test for leaks, and have you read the stage 0 free mods, it explains how to make a pretty useful tester so you might want to compare that to yours.

have you blocked off you BCS or MBC?- if not then thats BAD!

Does anyone have thorough instructions on how to do the boost leak besides making the device, the device is not complicated and was made correctly. Not sure what BCS and whatever is, but what I am saying is it is not get past the air intake side of the turbo therefore did not destroy antything, has not escaped through any of the plumbing, just seems to hold where it is at, and not letting an air pass.

Boost/Control/Solinoid- Manual/Boost/Controller- you must have this blocked off or it will never let the gas blow off

Dont be so offensive, he was just trying to help out. For all we know you did make it wrong.
