Search didnt work..NO VACCUUM??!
Whats goin on guys, so here is my situation. My car runs strong, drives smooth. I thought that it was just my boost gauge, so i switched it with another, but none of my gauges are reading vaccuum.... is that even possible? I mean my idle surges up and down. (have a boost tester coming in today to find the leak) But could that leak take away from all my vaccuum? ive never seen something like this before. Thought i would throw it your way, any imput appreciated, Thanks guys...
P.S. Its a fresh large streetport 10th ann. if that helps, No other serious mods yet. Thanks again!

It's not weird if you connected the gauge to a nipple that leads to a place prior to the throttle plates. On a USA turbo engine there are four nipples on the aft side of the engine. One above the other. Only one is vacuum. That would be the very bottom nipple.

^ I have my boost gauge tee'd into #4 in the pic, which is also going to my thermovalve. I use the bottom nipple on the front of the engine for my GM MAP sensor.
So in a stock car, what does number "3" go to on the 87 engines? #1 is injector air bleeds, #2 is oil injector air bleeds, #4 is water thermovalve on the TB on my 88

Do you feel lucky punk!!!
I also connect my MAP Sensor and the boost gauge to the bottom nipple on the front of the engine. In the bottom one on the rear I get 0 vacuum, so I moved to the front.
I have a question, were you guys connect the vacuum fitting from the wastegate and the blow off valve to an engine vacuum source?
