Boost Gauge help? Not reading boost
The gauge I have currently reads vacuum only. I have a vacuum line coming off of the plenum and no boost is read. However, when I put an air hose from a compressor to that vacuum line, it reads that air. What could be the problem? I'm currently on a vortech SC kit.
Thanks
Phil

Its a glowshift gauge... just something cheap I got for free. It doesn't leak though, as I use the same line from the bay with the air compressor.

Ive always been under the impression that you don't make boost until your under a load, so I've driven it on the street. Its a digital gauge, but it never reads boost. 2k, 4k, 6k, nothing.

the only vacuum check valve in the car that i can think of is inserted into the brake boost vacuum line that connects from the passenger side of the plenum to the pipe on the side of the firewall... so unless your boost gauge is T'd off the brake booster line... its too hard to say from here, unless you just arent making boost. Are you positive that the car is supercharged?
