i have a 94 z28 with p1sc prochager..my question is where does a boost gauge hook up on my setup?

 

Lots of places. If you hook it up before the intercoolers it will give you the boost reading from tha actual supercharger. If you hook it up somewhere on the intake it will give the boost reading that the motor will see. I would tap the vacuum line for the FPR that should give you a good reading. This might not be the best place but it will work and it will tell you what the motor see as far a boost.

THERE IS TO VACUUM PORTS IN THE SIDE OF THE INTAKE JUST ABOVE THE PCV VALVE I WOULD TEE ONE OF THESE FOR THE BOOST GAUGE THAT WAY YOU KNOW HOW MUCH BOOST YOU ARE MAKING

 

To get an accurate reading of your intake manifold pressure, tap directly off the intake manifold (the two ports above the PCV stated above is a good place). Teeing in further away from the manifold may give you an inaccurate reading.
