I have a boost leak that I can only hear over 40-45 pounds of boost. How can I track it down w/o disassembling the entire system?

Thanks.

Aren't all boost leaks invisible?

I know I can't ever SEE boost leaking at least. Check your ic ends. I remember reading about Matt having a crack in the weld that took him forever to find. Just an idear.

Ok guys, good info.

I had thought about plugging up the turbo like the diesel site product...

Dieselsite Turbo Boost Leak Detector - 4"

...but I had just assumed due to valve overlap that the pressurized air would just all escape out of the exhaust pipe. Soapy water at idle has not been able to find this leak but I can sure hear it at high boost. I don't think smoke would work just because I need high boost to have the leak (I think).

I need to get started making one of the turbo boost leak detectors like of my own to work w/ my 5" turbo inlet.

I will update you guys w/ what I find.

Thanks for the suggestions.

What about a leak on the exhaust side of the turbo? I.e. uppipes? I didn't know how bad my leak was until I replaced the pipes and gaskets. I still could get 25-27 psi off my stock turbo, but it was noiser.

Just a thought.
