BOV question (kinda stupid)

[yerrow]

dont take this the wrogn way but if your doing a turbo project im surprised your even asking this question. The bov only makes the hiss sound when the excess boost from the turbo comes through the piping that sound is that air being released. Do some research before you do the turbo so you know what you getting into. good luck.

actually you are wrong...the excess boost from the turbo is released by a wastegate. BOV's release the compressed air when the throttle is closed not allowing it to get to the turbo

well, the BOOST is technically on the intake side of the engine so excess boost pressure is released by the blowoff valve. excess exhaust pressure is relieved by the wastegate on the hot side thus controlling the boost on the cold side of the turbo.
