{"product_id":"m156-stage-2-supercharger-system-8-rib-67mm-pulley","title":"M156 Stage 2 Supercharger System 8-Rib 67mm Pulley","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.\n\nKey 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.\n\nThis 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.","brand":"Weistec Engineering","offers":[{"title":"Default Title","offer_id":52664121884984,"sku":"Stage 2 M156 Supercharger System","price":11999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687540613.jpg?v=1784333576","url":"https:\/\/store.motormia.co\/products\/m156-stage-2-supercharger-system-8-rib-67mm-pulley","provider":"MOTORMIA","version":"1.0","type":"link"}
