why? whats different when you shift rather than when you are in gear? is it because the turbo is still spinning fast thus still shoving air into the engine but because you are shifting, the engine is slowly winding down not taking in as much air so now you have alot of air with no place to go. damn i think i just figured this out. sweet. correct me if im wrong, or if you couldnt undertsand the way my mind thinks.

Basically...when you shift you lift off the throttle...so now there is pressure from the turbo heading for a brick wall (the throttle plate). The BOV will allow (normally) the air to be recirculate so that the energy of the turbo isn't wasted. If you feed it back in front of the turbo the air is already pressurized and fast moving so it allows the turbo to stay spooled better. If you vent it then the turbo just pushes air out of the intake. If there is no BOV then the turbo is pushing against the throttle plate and the pressure will actually try to impede the motion of the compressor while exhaust is still turning the turbine...stress, etc. The higher your boost settings are the more important it is to have a BOV and to have it re-routed into the intake piping. Low boost you might be able to get away with open air BOV venting...

Since you turbo the Lancer. What are you using for fuel? Any piggy back fuel computer like HKS AFR or GReddy Emanage? How much is the car boosting? Are you using a VORTECH fuel pressure regulator or an rising rate fpr?
Fred Hernandez <--want a turbo Lancer too and have some cash to spend on turbo kit if any.
