Over the weekend I replaced my shut off valve. After the replacement, and making sure all the tubes are on tight. I took it out for a spin, and I'm still not seeing any boost on my gauge. At this point I'm at a lost, and no idea what could be causing this. Can anyone out there help me?
Assume you mean by-pass valve. Did you zip tie the valve to test that it was working correctly? If the water pump is spinning then you should have boost. There is a recent thread here where they found that the factory pulley had come loose and was free wheeling on the shaft.
I never did the zip tie test before changing it out. I swapped in the DT bpv, so it should be working. I can feel the supercharger kicking in, so I don't think its a loose pulley. Are there any other factors I'm missing? Could my boost gauge be broken? All it reads is vacuum and maybe 1 to 2 lbs of boost.
If it is as you stated, "I can feel the supercharger kicking in," and you're NOT observing a noticable decrease in performance, then I'd guess yes, the gauge might be faulty, or disconnected at some point along the line...
