I figured I would get rid of a few of my vacuum lines that run my boost gauge, MAP, BOV, etc etc..
I bought a vacuum distribution block that will become a central distribution point.
My question is, can I just plumb the brake booster line in to it as the source instead of drilling a hole in my intake and tapping it for a nipple?
Anybody?

 

I used the intake as the main source of Vaccuum to the block1/4 NPT. After that, simply ran all other lines to the other ports1/8NPT. Very clean and simple.

 

i wouldn't run it in series with the booster, find a spot to dedicate the feed for it.

 

Yeah... better drill and tap it me thinks

 

Got it installed. Just tapped in to the back of the upper intake.
Have to BDC weld some holes shut after I make sure this will work.

 

I did something similar on Project OldTree using an air compressor manifold from McMaster-Carr. Basically, it's just a chunk of aluminum with 10 1/4" NPT ports and a 3/8" NPT port on either end.

It is fed from the 20B-REW's front turbo inlet (Constant Vacuum) through one of the 3/8" NPT ports while each of the occupied ports has a hose barb to supply vacuum to the intended devices. The manifold is tucked in the corner behind the passenger side headlight, next to the vacuum chamber for the twin turbos.

Pic of it:


I did plumb in the Brake Booster here and it works quite well based on my limited seat time. Granted, my turbos are not plumbed in yet, so I cannot comment on how it affects them, but I have not noticed any braking issues due to lack of vacuum assist so far.

 

Got it done and after driving it and putting it through the paces, I can honestly say thsi is the best thing I have ever done!
MUCH more responsive and everything works better!

 

Awesome. Been thinking about this for a while. What vacuum/boost sources were you using before?
