Product Information
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.
This system is a complete, bolt on system that can be installed with out any guess work or custom fabrication. Weistec has engineered and manufactured many of the components of this system to ensure a simple and straight forward installation. .
