Weistec Engeering Stage 1 63 AMG M156 V8 supercharger is now 50 state legal - CARB certification approved
A major congratulations is in order for Weistec who managed to pull off what many said would be impossible. CARB certification (California Air Resource Board) is extremely difficult due to the strict emission controls employed in the state. It is usually only large manufacturers making parts for domestics that have any luck with CARB certification using aftermarket superchargers (Magnusson, NOVI, Stillen) and we searched but could not find another modern example of a CARB certified aftermarket supercharger system for a Mercedes, BMW, or Audi. Not Dinan, not Renntech, not Active Autowerke, not VF-Engineering, not APR, not ESS, not Gintani, nobody producing superchargers for the aforementioned makes has achieved this on a platform produced in the last decade. That should put things in perspective.
