Details:

A vacuum block is a component that provides multiple and boost ports for connecting various accessories devices in supercharged engine setup. ProCharger also offers universal vacuum blocks for superchargers, whats a block. In this event the pressure builds until flow attempts to reverse direction and exit through compressor, resulting in a harmful condition known as compressor surge. Bypass valves are used with blowers since they always relieve the boost until near zero vacuum heavy throttle is achieved.

Stacked up boost will also try to find weak spot in the tubing and hoses blow out of. Blow-off valves are designed to relieve boost at a set amount of boost, and can cause stacking when used with blower. In high RPM, low load conditions, the supercharger is still operating at full speed and attempting to deliver flow. Installing a bypass valve between the supercharger discharge and carburetor/throttle body prevents damaging compressor surges by diverting un demanded charge air to atmosphere during manifold vacuum conditions.

This is why Bypass Valves are better than Blow Off. ATI/Procharger Part # AV004A-004B: Extended Details. Unless a blow off valve is properly set up with light spring though, the boost that built places load on blower hard it, plus it will try to slow down which can cause belt slippage. Valve Specs, Applications: Street/Race, Max HP Range: 700-1200HP, Inlet Diameter: 2.0 in.

Boost Gauges. ATI Procharger Race Bypass Valve, Details. Applications at higher power levels are best suited for use with our poppet-style race valve. Routing the hose past firewall quiets down release of air from valve.

With the throttle blade at or near fully closed position, engine is unable to accept airflow from supercharger. Importance of Bypass/Surge Valves, Applications utilizing inter cooling and those operating at boost levels in excess 8 psi will benefit from the use a bypass valve commonly referred to as surge.

This listing is for a Single ATI / Procharger Black Bypass Valve with V-band connection. Antis butterfly-type Pro-Flo is well suited for applications making 750 hp or less. Bypass Valves vs Blow Off Valves, Blowers are always producing some amount of boost as they belt driven, where a turbo spools up the exhaust velocity is increased.
