Description
Upgrade your M157 or M278 SUV with the Weistec ASV/WMI System, a comprehensive solution engineered to optimize performance and reliability. This dual-purpose system integrates an Anti-Surge Valve (ASV) and a Water-Methanol Injection System (WMI), providing exceptional power gains, enhanced turbocharger protection, and consistent performance in all driving conditions.
Key Features
1. Anti-Surge Valve (ASV)
Turbocharger protection is critical for preserving performance and longevity. The factory M157 engine lacks a bypass valve, leaving turbochargers vulnerable to compressor surge, a phenomenon that occurs when the throttle closes after hard acceleration. Compressor surge can damage turbochargers, stalling the compressor wheel and reducing efficiency.
- Prevents Compressor Surge: Protects turbochargers from damaging airflow backflow.
- Engine Vacuum Operated: Vents compressed air to the atmosphere upon throttle closure.
- Iconic Blow-Off Sound: Adds the "blow-off" sound, popular with modified turbocharged vehicles.
- Dual ASVs for SUVs and vehicles with Active Body Control (ABC).
2. Water-Methanol Injection (WMI) System
Harness the power of water-methanol technology, a proven performance enhancer for turbocharged engines. Originally developed for aviation, WMI systems reduce intake temperatures, prevent knock, and boost power output.
- Progressive Controller with MAP Sensor: Ensures smooth, seamless injection as boost builds.
- Red Powder-Coated Turbo Charge Pipes: Includes built-in injector bungs for uniform cooling.
- Significant Gains: Up to 100 HP and increased torque* with proper tuning.
3. Engineered for Precision and Simplicity
The Weistec ASV/WMI system is tailored for M157 and M278 engines, ensuring flawless integration and easy installation. Unlike universal kits, this bolt-on upgrade eliminates guesswork and delivers optimized performance.
- CNC-Machined Injector Bodies: Includes check valves for reliable functionality.
- Trunk-Mounted 2.25-Gallon Tank: Features a racing cell cap and integrated pump mount, fitting discreetly in the spare tire well.
- Quick-Disconnect Fittings: High-quality fittings for effortless maintenance.
Complete Kit for Hassle-Free Installation
Everything needed for installation is included in this comprehensive kit, designed to enhance performance without the need for custom fabrication or modifications.
