There are a couple of things that you can do to make your supercharger louder. Some of our superchargers are so loud that they scare people when we race against them.if anybody know something to make the SC charger sound can be more powerfull let me know.
I don't understand why it couldn't be done.
Venting air already metered by the MAF to atmosphere is the biggest problem. The BOV is intended to protect the turbo from damage. When the throttle plate is closed and the turbo is still spinning the air has to go somewhere. If you don't allow the pressure to be released it can damage the impeller blades and cause the intake track between the turbo and throttle body to become overpressurised causing other problems.
