This might pertain to make fake blow off vaaaaallllvee. But its a serious question, that I wondered anyways.
For 2gnt turbo's with a BOV. I dont know much about BOV's, but if Im correct, one connection goes to the hose with the compressed air coming from the turbo. Another, smaller, hose goes to the vaccuum line on the throttle body/intake manifold. And another is for the vented air to go out. Soooooo... Where does the vaccuum line go that once hooked up to the intake manifold before you put the BOV on?
