The bypass valve is a release which vents off pressure in a rapid de-acceleration situation. When the Supercharger is producing boost and you abruptly let off the gas, closing the throttle plates, the boost has nowhere to go (also known as compressor surge) kind of hard on everything. The Bypass helps relieve this and also helps smooth out your idle. It is also helpful in building up boost faster, and as a bonus, it helps to prevent parasitic power loss. Under idle or normal driving (vacuum) the valve is open. When it sees a boost signal it closes.

I have one very loud bypass valve on my Hellion turbo kit.

Nothing like running wide open by someone with that loud v8 growl then let off and you hear a loud "pssshhh"

Sometimes I feel like a ricer becuase my car makes that noise
