The BOV is actuated by the pressure in either the manifold or the hose
between the turbo and the manifold.
When the pressure in the manifold reaches a certain point, ie 10 psi then it
activates a valve which pushes a rod and that opens a bypass valve for the
exhaust gas.
Kinda hard to explain, but I got a book on it and I can scan some pages for
you if you wish!
