butterflies/ fpr vacuum source

[kahlistrophic]

Hey everyone, Ive been through the FSM and used search..I guess Im just thick...Im gonna put some pics here and can you please tell me which of the circled lines on the back of the intake manifold should i get my vacuum source for the fpr/butterflies from. just a simple answer.

thanks

I made this for a local board:



Note: this diagram does not include provisions for a boost gauge. Just tee off one of the lines on the intake manifold and you should be set.

Here's a more detailed pic (thanks biosehnsucht) from the FAST manual showing exactly how they are routed:

i am just going to say wow to that diagram....if it were floating around the forums a couple of weeks ago that would have been sweet.....there is one but this one is in better shape and laid out a little better/easier for some of the new people to understand

this is all assuming you have the proper hardware to correctly set up your vacuum. I just want to know without a vacuum tank, where to get my source from the intake manifold as shown on my pic.

straight to the back nipple on the manifold then. run a vacuum manifold from the manifold to boost controller, fpr, butterfly actuator, and boost gauge.

kinda hard to see exactly what you picture is pointing to.. but it looks like the highest circle on the 1st pic on the back of the mani like stated and just T it for both of them (or use a Y i heard they are suppose to flow better or something)

What if you don't have the selenoid or the delay valve??

Meh. Pull the lower mani and ditch em. Most folks that I have talked to say the increased top end outweighs the slight bump in torque they provide. I may do just that this summer if I get the time.
