Show original supplier description
The Weistec Stage 2 M156 Supercharger System is engineered to significantly enhance the performance of Mercedes-Benz AMG 63 models equipped with the M156 engine. This comprehensive system includes an 8-rib drive setup and a 67mm supercharger pulley, designed to increase boost and leverage the full potential of compatible high-flow exhaust components. Key performance gains are substantial, with the system capable of delivering up to +221 horsepower and +219 lb-ft of torque. To fully integrate the Stage 2 system and achieve these power increases, recalibration of the ECU to Stage 2 specifications is required. This supercharger system is specifically designed for various AMG 63 models, including SL63, R63, ML63, CLS63, CL63, CLK63, S63, E63, and C63 AMG vehicles. It is noted that the upgrade includes recalibration of the ECU to Stage 2 and a new supercharger pulley to increase boost and take advantage of long tube headers. Compatibility may also depend on specific vehicle configurations and the presence of certain exhaust systems.
