Forge MBC

Just wondering how do i hook up a forge MBC. Because the one i got now only has to plug in spots and this one has 3 ports.

I have a Forge MBC. There were only 2 spots to hook up vacuum lines, so I don't understand what you're talking about. pics?

cap one of those side ones off and the inlet is the side opposite the dial, and the other spout goes to the wastegate. I got bored so i modified SBR's cheat sheet for ya.

Yea Thats what i was thinking of doing. Didn't know if it would be right or not.

Does it matter if i plug the WG hose on the side or the bottom?

[Halon]

Yes it matters. The pressure source must be connected to the bottom nipple. And the wastegate must be connected to one of the side nipples. Man I love the word nipples!

[98gstaherns]

Thank you! So is the hose that runs from the BOV line is that the pressure line? Or the one that runs from the WG?

[Shane55113]

yeah pressure comes from the intake manifold when the throttle plate is restricted it "pulls" the bov open and opens the wg via boost controller.
