    Importance of Bypass/Surge Valves
    Applications utilizing intercooling and those operating at boost
    levels in excess of 8 psi will benefit from the use of a bypass
    valve (commonly referred to as a “surge” valve). In high RPM,
    low load conditions, the supercharger is still operating at full
    speed and attempting to deliver full flow. With the throttle
    blade(s) at or near the fully closed position, the engine is unable
    to accept the airflow from the supercharger. In this event the
    pressure builds until the flow attempts to reverse direction and
    exit through the compressor, resulting in a harmful condition
    known as compressor surge. Installing a bypass valve between
    the supercharger discharge and the carburetor/throttle body
    prevents damaging compressor surges by diverting the
    undemanded charge air to the atmosphere during manifold
    vacuum conditions. ATI’s butterfly-type Pro-Flo is well suited
    for applications making 750 hp
    or less. Applications at
    higher power levels are
    best suited for use
    with our
    poppet-style
    race valve.
