Hi,
I was wondering if everyone can tell me how they hooked up their vacuum lines using the intake manifold ports (the 3 ports on the left and the brake booster ports). I've been redoing mines and I seem to get different hg readings all the time - none of them too good. This is in the turbo section because I was hoping those with turbo setups can give me their inputs, thanks. This is my setup:

3-ports: Left - fmu
Middle - fpr
Right - profec-b

Brake Booster - BOV

Now if I could remember correctly, someone in the board used the brake booster port instead of the wastegate for the profec-b (and just connecting the wastegate to the intake manny).

This may not be the answer you're looking for, but I intend to redo my vacuum setup w/ this manifold or one similar to it (prob early next year).

Or you can always tap the manifold for new vaccum sources.

that item looks pretty cool. But I probably wont need so many ports...so anybody who can provide me with their setup would be much appreciated.

I kept stock fpr, all i had to hook up was the boost gauge, fmu and bov, and i tee'd them all off the port on my intake mani where my egr vac line use to go. so i have all 3 comming off that one source. as far as i can tell it works great and i have no issues, the vac gauge stays around 20-23 while idle'n and the fmu seems to be getting proper boost reading cause while in boost my a/f gauge is in the green, if im wrong here somebody please let me know so i can retap some lines but i would think its ok

From left to right on a Venom Intake Manifold:

-Boost Gauge (added tap)
-Brake Booster
-Cruise (now gone)
-BOV
-SFMU
-PCV Valve
-Wastegate

you can see the 2 fittings I added in this monster pic:

i have my brakebooster taking the profec and bov. fmu is the far left and the middle is my boost gauge. from what i can tell, its pretty close as far as being "accurate". my profec is set for 10psi and spikes usually to 12, and my gauge reads a hair shy of what the profec does.

I used a dedicated line for the WG. One for the BOV and the SFMU and one for the EGR and Boost gauge.

that thing looks cool. is anyone using it?

left-fmu
middle-ac compressor
right-bov/boost gauge

quite a few different types of vacuum manifolds around

I'm useing one of those....works pretty slick. I'm pulling the vac from the brake bolster line. So it goes, intake manifold > vac manifold > brake bolster. The I have the same size line going into the vac mainfold that goes to the brake bolster. And it has 6 ports with a line going to each of gadgets, fpr, EIC, boost gauge and BOV. With I think 2 ports plugged. FYI I run the WG right off the turbine housing.

I got my manifold for free at work....we use them all the time. It pays to work for a machine shop :thumbsup

Wastegate and fmu should have their own vac/boost sources with the shortest lines possible. All others can be T'd off the last port.

yeah...I actually most of the stuff hooked in their vacuum now. Before they were all tee'd off with one another but I fixed it. For the wastegate I connected it to the boost controller. I'm suppose to leave the top port open right? I got an external wastegate.
