Can someone tell me the markings on both of these valves. I think I may have them reversed.

 

I'm not sure about the markings, but when I ordered my new valves both operated in the same range (fully open at about 8 inHg). So I don't think that it matters which one is which. When I tested the vacuum in my system during turbo operation, the vacuum going to the charge relief valve was around 20 inHg, and since the air bypass valve is controlled directly off the intake manifold(>20 inHg when throttle is closed and RPM is above idle) the vacuum required to operate both valves is well below what they will actually see. Hope that helps.

 

Thanks!
