all boosted cars with a turbo have a BOV. Do you even know the purpose of a BOV?

Do you realize how dumb you just sounded? You dont HAVE to have a BOV, but it is better to have one.
And btw, my friends dad has a 5.0 mustang auto with turbo and BOV.

When you step on the gas in a turbod car it opens the throttle body and builds some boost. When you let off the gas, the throttle body quickly closes and the turbo keeps building boost because it's still spinning. So the vacuum from the intake, because of the closed throttle plate, sucks on the top of the bov diaphragm making it easy for the leftover boost in the intake tubing to vent.

This happens no matter what transmission is in the car...

Someone actually explains what goes on. I'm so used to the "No, gosh your so retarded"
