Shopper Award
The Weistec ASV/WM Injection System adds multiple beneficial components to the M157 BiTurbo 5.5L engine. First being the addition of a Weistec Anti Surge Valve (ASV). From the factory the M157 engine was never given any type of bypass valve. Without a bypass valve, the turbochargers are subject to compressor surge when the throttle closes after hard acceleration. Compressor surge can be damaging to turbochargers and generally should be prevented to help ensure the best performance from the turbochargers. The Weistec ASV is operated by the engine vacuum, opening when the throttle closes allowing the compressed air to be vented to the atmosphere instead of back flowing into the compressor housing and stalling the compressor wheel. The vented air produces the "blow-off" sound common on many modified turbocharged vehicles.
