so i have had my car turbo for about two months now with a hahn stage 2 kit w/ sidemount intercooler. everythings been fine until yesterday when my car will not boost! it just sits on zero and will barely creep up to 1 psi. what should i check to fix this? thanks

i would do a leak down test. make sure one of the couplers on the ic piping didnt come off or loose up. other than that im sure others will be able to give more advice. hope that helps.

A leak down test is for finding out where your engine is blown.

A boost leak test is for finding out where the leak is in his IC piping.

He wants to do a boost leak test.

Use the link in my sig to find out how to do one.

A friend of mine had that same problem....some how his boost gauge tubing got a slit in it and was letting the pressure out before reaching the gauge. All we did was get some get some RC fuel line and some clamps from a hobby shop that cost $5 tops and repaired it.

i highly doubt that a cut in his boost line would make the car have no boost, mabey the gauge, but that is it.
Sounds like you have
A: Intercooler pipe blown off
B: Wastegate arm has fallen off the flapper.

Check both those things, if neither one of them is bad, you may have more problems than you think.

thats the whole point...maybe there is boost but the gauge is simply not reading any. Are you saying that you don't have any boost at all or the gauge isn't reading any boost?

the problem has been fixed...it was just the wastegate actuator. all is good now. thanks

how did you figure that out? Because my friend is starting to have some boost trouble similar to yours.
