Anti Surge Valve System
The Weistec ASV System adds a Weistec Anti Surge Valve (ASV) to the BiTurbo AMG M157 and M278 engines. From the factory the M157 engine was never given any type of bypass valve. With out 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.
INCLUDES: Charge pipes x2 (red), anti surge valve x1, vacuum/boost adapter, hardware
VEHICLE: Mercedes S-Class W222 S63 AMG / S550 w M278 / M157 Engine 2014-2017
