ok so i got my car back from the shop today and had the car in the drive way just running and i go under the car and hear mass air comming out of the bypass valve i am sorry i dont realy know alot about supercharger but i didnt think that would happen i might be wrong anyone know?

 

That's normal. The bypass valve remains open until you open the throttle body (letting in the boost the vortech is creating) by depressing the gas pedal.

 

ahh ok good now i just have to fidn out y it wont let me go passed 4,000 rpms
