What part of the vehicle do I hook up this mechanical boost gauge too, to get psi boost reading? I have a saleen series IV supercharger installed onto an 2003 mustang GT.



Thanks.

kind of helpful but my vacuum boost gauge tube just pushes over onto a barb I dont have fittings that that twist onto anything. Its all about pushing onto a t-fitting and onto the boost gauge.

 

connect it to the red vacuum lines that go to your intake or the fuel pressure sensor .

 

Ive tried all that on this supercharger with this mechanical boost gauge and I keep getting a negative 30 ready and when I give it gas it goes up to a negative 20. I tried the EGR selenoids top barb and bottom barb. The top barb does nothing makes the gauge sit at zero as if I didn't even have it hook up as before and the bottom barb shows a negative 30 and when given lots of gas barely moves up to a negative 20. Tried hookin it up to the supercharger bypass valve which connects to the fuel pressure sensor and get same reading negative 30 lots of gas and barely negative 20. This saleen supercharger use to have an electronic boost gauge sending unit on the side of it but has been removed and now bolt plugs hole. Do you all think I have to get an electronic boost sending unit to make this work or should it work off of vacuum?
