Vacuum Line Location

RE: Vacuum Line Location
brake booster line. It comes off the back of the intake manifold and gives an accurate reading of the PSI right in the intake manifold, so its better htna the turbo's vacuum nipples because it takes a reading after the air has traveled through the Intercooler and charge piping.

RE: Vacuum Line Location
my bad... I should probably specify more. I meant my wastegate actuator. Not boost gauge. I was told the vacuum line was to be as short as possible for the actuator, so it has good response and can open and shut effectively.
another thing... my wastegate is stuck open right now, any suggestions?

RE: Vacuum Line Location
I have an edelbrock intake manifold which already has a nipple to connect my wastegate line. But, what most people do is buy the eagle's vaccum thingys, and tapped it to the brake boost line... and just connect the wastegate line and other vaccum lines to it.
Or you can do it the ghetto way, which is buying some t-fitting and tapping the wastegate line to any intake vaccum line.

^ thats what im doing. Running my vac mani off of my brake booster, than running my BOV, boost guage and wastegate all off of that. From Forty:

You are correct on the Vacuum Manifold. What you do is Cut the Brake booster line AFTER the one-way check valve, so that the valve is in between the vacuum mani and the brake booster. Run the brake booster line into the side of the vacuum mani, then from one of the ports on the mani, connect it to where the brake booster line used to be hooked up. Then, put in as many nipples as you need, and run your lines

I am trying to find the best spot to hook up my internally wastegated 14b vacuum line. Any suggestions? Someone told me the intake before the turbo. To me that just sounds stupid...

sometimes they have a brass nipple on the compressor housing that is a vacuum port that you can use to send a boost/vacuum signal to the wastegate

the brake booster is said to be better than that (although it IS farther from the wastgate), just becasue once the air travels through the piping it might be significantly less PSI than what was originally compressed in the turbo itself, so you'd be making less power than getting a full "X" PSI at the intake manifold
