wastegates with vacume and boost source?
 

looking closer at my deltagate... it's got a place for a vacume source as well as the boost source...

whats the point of it having the vacume on it?

thanks

the vaccuum is the bottom nipple. you hook this to your intake mani for a source. the top nipple isnt used. i teed my boost comtroller into the line for the vac port. and left the top boost port open to the atmosphere

i know the side one goes to your boost source (manifold or the turbo or whatever)

but why is that bung on top threaded?... i just know i've seen a few internal gates that are supposed to have a manifold signal and a turbo signal (direct from mani and turbo) if i rember right it's HKS dual port gate or some crap like that

just wonderin
thanks
