No boost with my procharger setup?
No boost with my procharger setup? Cant understand whats going on but my 02 camaro I bought a procharger system for the p1sc, anyways I installed it and everything went on like it should.. starts n runs fine.. issue is, it will not create boost.. I checked and replaced my boost gauge just to be safe but it is not boosting.. I dunno why..
the pop off valve is working as it should from procharger, everything is installed to spec. but at idle I have vacuum, once i give it some pedal it goes straight to 0, no boost no vacuum.. i dont get it.. belt isnt slipping, pop off is working.. I took off the charge pipe to the intake to just see if it was blowing air, and yes its pushing air, a good deal of it.. so I cant understand that if its blowing air, why does my gauges not show boost?
I can blow on the gauge myself and get 3-4psi but once installed on my motor nothing but vacuum..
somethings not right.. i just am confused.. procharger seemed confused also.. do you guys have any idea why or how this is happening??

are you revving it or are you on the street and putting load on the motor?
it will not make boost just sitting still and revving up the motor, there needs to be load.
if it still is not making boost then you have a BIG leak.

we have a load on it. and nothing.. as for a leak i have to agree cause it sounds right but i cant find it.. only place i can feel or hear air is from the pop off valve and it works as it should. everywhere else i cant hear or see any air moving at all..
Sounds like the same problem i had...
I pulled the vacuum for my gauge and the BPV off the intake...
For one reason or another the "fitting" that i attached my vacuum line to was actually a one way valve.
If its the same problem as mine, you can pull it out, and try to blow air thru it... it would only allow you to blow one way (not both). I removed that and replaced it with a normal straight thru plastic vacuum fitting, and that fixed my issue.
Might want to give that a look / try, sounds exactly like my problem.

The best place to pick up vacuum for the bypass valve is off the passenger side of the firewall, T'ing into the a.c. vacuum line. Bob

I'd run the bypass valve off the HVAC line back at the passenger side of the firewall. Bob

Right off the line going to the brake booster should be good. That is where I pulled my vacuum for the bypass valve and boost gauge.
You are either pulling off a line that only sees vacuum or you have a serious leak.

Make sure the supercharger has a belt.........................................j/k
I'm guessing the bypass is stuck open or you have a massive boost leak.
You may want to try disconnecting the vacuum line to the bypass and just rev it up a bit to see if it makes a little boost - don't go crazy because it isn't great for the supercharger this way.
I had an interesting problem on one car. The inlet into the supercharger was rubber. Everytime the car came up in rpm's the supercharger would pull vaccum on the inlet line and collapse the rubber and made NO power. Took me a bit to figure out what the hell was going on.
