waste gate operation

[Konstantin Bogach]

Ameer,
my knoledge of it kind of shaky cause I have some questions on it as
well but to my shaky one the lower chanber hose (bigger one) is
connected to intake manifold and waste gate frequencny valve mixes
manifold pressure with atmospheric pressure. Lower chamber pressure
opposes WG spring and mixed pressure assist spring. I never saw
discription how it works. This is what I came to using deduction method.

If you pinch off lower hose you will get overboost very easily.
