BOV and Vac
 

Does a BOV need vacuum? I was informed it runs off pressure. But if someone can correct me on this.

Re:BOV and Vac
 

the vacuum created inside the intake manifold when you close the throttle plate will "suck" the bov open to release the pressure from the turbo

Re:BOV and Vac
 

yes you need a vacuum line

Re:BOV and Vac
 

Because I have my bov ran off a barb in my charge pipes next to my throttle body. Wondering if I should move this to the brake booster line.

Re:BOV and Vac
 

there should be one going from your intake manifold to the fuel pressure regulator or something similar which would be the best one to use

Re:BOV and Vac
 

I always heard for BOV that brake booster was the best?

Re:BOV and Vac
 

i've never heard of using the brake booster vacuum, but i guess it's all the same... on my 89 supra turbo the bov is actuated by a vacuum line coming from the intake manifold, if anything, i would say this would allow for the quickest bov actuation

i just t'd everything off my fpr vacuum line (bov, boost gauge, btm)...easy to get to and works well. wastegate is off the nipple on turbo compressor.
