Searching is slim on setup. I have a 44mm setup coming out before the turbo in a log setup. I have a 5psi spring in and tuning for 10psi. should i run my lines out of my vibrant vacuum manifold to the boost controller into the top of my gate? or run a line out of my vacuum manifold to the bottom of gate and regulate the the top line to the gate? opinions or suggestions appreciated!

 

top of gate is generally for electronic boost controller. if you have a manual it will generally go between the vac source and the side of wg

i run a line out of the end of the compressor outlet to the side of wg, then if do a controller i put it in line with that

 

It is a manual controller. So run it out of comp housing into controller out of controller to bottom of gate is what your saying?

 

usually fittings would be on the side of the gate.

 

I'm pretty sure that my manual boost controller is hooked to the vent side of the waste gate. Other wise you waste gate would only see the amount of psi that the regulator is set to.
For example if you had the regulator on the line between your manifold and the waste gate and the regulator was set at 5psi but you had a 7psi spring. The regulator would never let over 5psi through it. Therefor you would over boost your motor because the gate wouldn't ever see 7psi to open.

I could be wrong, it has been so many years since I have screwed with mine and my truck is at the shop. I will double check this tomorrow.

 

Yes, you are thinking about it wrong. In your example, the manual boost controller will not open UNTIL 5 psi. Not regulate it below it. Say you had a 10psi spring and your boost controller is set to 12, the wastegate will not open until it sees 12psi.

Here is a good page all about how they work.

Problem with doing it that way is you have nothing to hold the wastegate closed if you want to raise boost. Sure your reference line would be set to limit the pressure to the gate but what about exhaust pressure. It will open the gate itself unless you have a pressure line on top to help hold it closed.
I always reference off the manifold so the gate sees manifold pressure not turbo pressure. The controller should go on top so it can apply closing pressure for higher boost.

 

Manual boost controllers (ball and spring) go in between the turbo and bottom of the waste gate.

only thing they do is bleed off pressure

 

Electronic BC are only ones that should be using top port

 

Since when? The exhaust will push the valve open when back pressure gets high during high boost. I guess if it works for you then have at it. Every one I've done has been the way I said. Hell I took a guys truck back to stock that had a sts kit on it. It was hooked up just like I described as well.

Ok ball and valve type I can see going inline with the reference. But to say manual controllers is misleading. Cause the kind that use what looks like a air compressor valve go to the top to apply pressure.
