The most obvious symptom is loss of boost. What happens is the rubber diaphram blows apart (disintegrates) and the rubber can go into the turbos. The problem is that you might not know they blew and that can lead to pre-mature turbo damage. Consensus is that when you are boosting over .7 bar, you should just change them to prevent this damage.

Quote:

in between shifts when the valve is suppose to open to re-circulate the built up boost pressure, if it is defective and cannot open, the built up manifold pressure will "stall" the compressor of the turbocharger causing it to rapidly slow down which can cause turbocharger failure. This "stalling" of the turbocharger will also increase turbo lag in between shifts and reduce power.

from EVOMS. It called searching.

Dave, Congrats again on your Turbo. But you may not "need" these valves with your mod list. At least consider a V-Flow/BMC and GIAC (both from the EvoMS family) to accompany them.

Agreed. He will not need the DVs unless he does some modification like a flash. As I typed earlier if the car is boosting stock the stock DVs are fine.
