Weistec ASV/WM Injection System for M157 BiTurbo 5.5L Engine

If you're looking to boost your M157 BiTurbo 5.5L engine's performance, the Weistec ASV/WM Injection System is a fantastic choice. This system introduces several key components that work together to enhance your driving experience.

What Makes This System Special?

One of the standout features is the Weistec Anti Surge Valve (ASV). Unlike the factory setup, which lacks a bypass valve, the ASV helps prevent compressor surge when you close the throttle after hard acceleration. Compressor surge can be tough on turbochargers, so having this valve is crucial for maintaining optimal performance.

The Weistec ASV operates using engine vacuum. When you lift off the throttle, it opens up, allowing compressed air to vent into the atmosphere instead of flowing back into the compressor housing. This not only helps protect your turbochargers but also produces that satisfying "blow-off" sound that many enthusiasts love.

Easy Installation

Worried about installation? Don’t be! This system is designed to be a complete, bolt-on solution, which means you won’t need to worry about custom fabrication or complicated setups. Weistec has engineered and manufactured many of the components to ensure a straightforward installation process. With this upgrade, you'll experience gains in performance and consistency that are hard to beat.
