Active Autowerke, established in 1981, has become a highly regarded name in the BMW community, known for their top-notch power solutions for various BMW models. This supercharger kit they offer packs a punch, capable of generating over 400 horsepower for your BMW while ensuring the vehicle's structural integrity and suitability for daily driving. What sets this kit apart is the Rotrex supercharger's design, featuring a traction drive system that eliminates the lag commonly associated with other centrifugal superchargers. This results in a smooth and reliable power delivery experience.

Key components of the kit include the Rotrex C38-92 trim supercharger, an Active Autowerke front-mount air-to-air intercooler, a high-flow fuel pump, supercharger brackets, pulleys, and belts, six high-flow fuel injectors, an Active Autowerke air filter, dyno-tuned software, and all necessary mounting hardware, plumbing, hoses, and clamps. Additionally, the kit comes with an illustrated instruction manual and installation guide, ensuring a straightforward installation process. Active Autowerke also offers a 2-year warranty along with free technical support for added peace of mind.

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent.  The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories.  These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

Rogue Engineering Power Pullies are CNC machined from 6061-T6, heat treated aluminum and specially coated with a MIL-A-8625 Type III hard coat anodize finish. This kind of anodizing is not to be confused with a Type II cosmetic anodize finish (typical colors such as red, blue, silver, green, etc.). The hard coat anodize finish actually builds a small surface layer on top of the aluminum, preventing wear.
