  • Advertised gains are estimates of HP and Torque “at the engine” calculated from gains as measured on a Dynojet Dynamometer in ideal conditions and typically show the largest possible change.  Actual gains are dependent on the following: Learn More

    Model – Manufacturers use the same engine in multiple model vehicles and often times they are in a different state of tune, for example: 2008 C63 and a 2008 CLK Black Series.  Both have the same engine, but the C63 has 451hp while the CLK63 has 500hp.  Naturally the C63 will show more gains as it starts at a lower level.

    Model Year – Similar to above, as time progresses, Manufacturers tend to slightly increase power output via software from one year to the next or offer “Performance Packages” with increased power.  The engines remain largely unaltered and as a result, final tuned output remains the same, while the gains are lower as the starting point is now higher.

    Fuel – Fuel quality is HIGHLY important with performance vehicles.  Low quality and/or low octane fuel will greatly impact engine output and potentially even engine health.  Top tier brand premium fuels should always be used to achieve the best results possible.

    Drivetrain – All wheel drive has higher drivetrain losses than rear wheel drive.  This results in lower numbers when testing on a chassis dyno.  Wheel/tire size and weight will also impact chassis dyno results

    Weather/Conditions – Temperature, humidity, altitude, and air density all impact engine performance.  Heat, high humidity, and thin air will all work towards reducing engine output

    Engine Health – Higher miles tends to result in increased build up and lower compression which can and will impact engine output.  Properly maintained engines will have better performance than abused or neglected engines.

    Supporting modifications – The highest power levels require supporting modifications.  Depending on the engine, this could mean forged internals, built transmission, upgraded fuel system, 110+ octane race fuel, etc.

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.




Maximum Performance

We have taken our proven supercharger design concepts and applied them to create the most efficient, reliable, and powerful upgrade ever available.


Maximum Performance

Our Supercharger System for the M113K engines provide much larger capacity, much more efficient cooling, and is a much lighter unit than stock.


Maximum Performance

The factory unit restricted air flow.  Naturally our engineering team incorporated a much larger opening to reduce restrictions.


Maximum Performance

We've also given our clients options for throttle bodies.  Both stock and the optional 82mm Throttle Bodies are able to be mated with our 3.0L Supercharger System.
