Boost Drop Off?

[Mr_G]

Hey guys,

Got a quick question as im experiencing an a inconsistent boost drop off.

Basically whats happening is the car hits full boost, then the boost falls off to half of what it was doing ie set @ 14psi, but drops back to 7psi. The only problem I can think of why its doing this would be the broken intercooler mounts. All pipe clamps are tight, the boost controller is a profec b spec 2 and I do know how to set it up.

Ive got 2 mounts on the bottom of the cooler, well had 2 mounts. They were welded onto the bottom, and have fallen off and taken part of the core with them, leaving part of the bottom layer of the cooler exposed.

Would this be causing my boost drop?

I would like to know this as well.

As i remember reading a very long time ago, that if you end tanks have a crack or leak, your pressure will drop heaps..

But im not sure about the core itself.

Measure pressure before, and after cooler.

That will tell you if you have a cooler leak quite easily.

seal the turbo intake pipe and insert compressed air into the turbo system .. then use your ear and soapy water to establish if there is a leak.
