Turbochargers are engineered to pump higher levels of air into the engine for more oxygen. Blow-off valves are utilized to regulate this elevated level of force to prevent potential engine or turbocharger damages. When a turbocharger is producing boost pressure and the throttle is unexpectedly closed, like when you're shifting gears or decelerating your vehicle, pressure rapidly builds up between the compressor and the throttle body must have somewhere to go. Should the pressure move continuously forward, the throttle body may get damaged but if it goes backwards the turbocharger can suffer. A blow-off valve features an integrated spring and diaphragm like a wastegate actuator that is connected to the engine vacuum. Vacuum that opens the valve is produced when the throttle closes. Blow-off valves reliably release the pressure to the atmosphere as the bypass valve releases pressurized air back into the intake air stream before the turbo.
