can someone send me a link for a proper vacume setup,or make one...

i`m using
-vortech Fmu
-delta-wastegate
-manual boost controler

on a Gsr with a Blox intake manifold... i haven`t placed the motor in the car i just want to compare and make sure i have it ran correctly..

Basically, anything that needs a vac and/or boost signal can be tapped to any source after the throttle body that sees manifold pressure. If you only need a boost signal, and don't require a vac signal, you can tap that from the compressor housing, or anywhere on the charge piping. As for the MBC, depending on the type, it'll most likely go inline with the vac line to the wasetegate.

Boost signal from IC piping/compressor is not a good idea... due to pressure drop across the IC and piping.

Tap everything off the brake booster before the check valve.

I always ran fine with boost signal off the compressor housing, and I use a nipple in the charge piping for the boost source for my EBC. I don't think it really matters unless you're just running off the w/g spring, in which case you would prefer that the w/g sees actual manifold pressure before opening. Pressure drop is a tradeoff for faster boost signal response, and it doesn't really matter if you're feeding the top port of the w/g to control boost levels anyway.

thank you but, what everyone has said is common knowledge.. i`am actually looking for "diagrams" maybe manufacturers, or boost setups for the most efficient, or most functional... if anyone has some links let me know...

I've done this too.. but it only works with an EBC...

Using a manual boost controller on an intercooled turbo setup, you're gonna want it reading the manifold. Even with the EBC, the WG is going to open sooner than it would, since higher pressure is seen on the bottom side of the WG diaphram.

Ok, here's a diagram:



Now Tee into the brake booster line before the check valve, and run all vacumm sources off this location using additional tees or a vacuum manifold. The MBC goes between the line from the pressure soucrce (brake booster line) and the side port on the wastegate.

You're welcome.

here is my setup:

so why did you do that ? and how do you keep a consistent vacume/pressure for each line ?

dustin

I did it so that I have strong pressure signal everywhere.

All of those lines are connected to the same vacuum manifold, so they all have the exact same pressure.

blacktegmd

i couldn`t tell if the was a solid block or not.. is it a part you made or purchased ?

dustin

I bought it from mcmaster.com

taken from someone else's post:

Should be about 27.50 shipped.

-----vacume : 29.9" Hg @ 73° ----- part# 44555k131


so you connect six of these together and they keep a consistent vacume for each ???

i used the vacuum manifold for all my connection...ebc..bov..gauge..wg..and FPR...i've had no problems with that..plus it looks good and clean..i used only one tee and that was a brass one for the the supply of the vacuum mani..i tapped at the brake booster line it's a larger hose so you get a good source...just make sure you tap it before the brake booster check valve...

blacktegmd

sounds good.. thank you..
