For supercharging applications, surge occurs when excessive boost or pressure spikes as a result of a sudden throttle blade closing, which can cause severe damage to a supercharger and is why we mandate all ProCharger supercharger installations use a bypass valve.
Race Valve: This is the industry leading surge valve for both street and race applications. The larger valve diameter is designed for high flow applications. This valve is designed for 701-1200 HP applications
Vent Styles
Open: Vents to atmosphere and creates a distinctive “whoosh,” when the throttle blade suddenly closes, which a lot of people enjoy the sound.
Enclosed: Vents to an external air filter or an internal tube via a 2" outlet for rerouting excess boost pressure back upstream of supercharger for a more quiet and subtle sound. More ideal for street applications where someone wants more of a silent or stealth operation of the supercharger.
