WEISTEC M113K Supercharger System


2002 was a milestone for Mercedes and European sports car enthusiasts. The AMG 55 equiped with the M113K could only be described as a game changer. When AMG transformed the production Mercedes 5.5L V8 into a Kompressed monster, there were not many cars left in the world that could overtake it. The factory forced induction engine lead to an entire industry of Mercedes aftermarket, an industry that has squeezed every last drop of power from the stock Kompressor.

It has been 10 years from its original release but it is time for todays game changer. Weistec is proud to produce the M113K 3.0L Twin Screw Supercharger System. We have taken our proven supercharger design concepts and applied them to create the most efficient, reliable, and powerful upgrade ever available.

Using our 3.0L Twin Screw, we have set the record for the Worlds Fastest Mercedes with our Stage 3 M156 Supercharger System. Producing engine power levels exceeding 1000 Horsepower.
