Why Rotrex?

www.kraftwerksusa.com KraftWerks Performance Group is proud to bring you the most advanced Supercharger system available. At the core of each KraftWerks Supercharger kit is the revolutionary and patented Rotrex, traction-drive Supercharger. The proprietary design allows for reduced weight; smaller, quieter, cooler operation; and shaft speeds in excess of 200,000 rpm. No other forced induction method can compare to Rotrex's superior efficiency, unmatched performance, reduced emissions, and transient response. KraftWerks Supercharger systems are designed to deliver broad, usable power gains—ideal for street cars and track cars alike. No other Supercharger kit or turbocharger system can compare. KraftWerks Supercharger kits represent the pinnacle of forced induction, having demonstrated gains in excess of 100% across the entire powerband on a number of applications. Each KraftWerks Supercharger kit is designed in-house at our state-of-the-art, Norco, Calif., facility with applications available for a variety of vehicles.

Tech Talk 3: Superchargers and Turbochargers
It's "Life After Wide Open Throttle" in this third episode from the Twilight Tech Talk series at the NHRA Museum in Pomona, CA. Watch and learn about "density machines" and how power output is determined. Gale talks about the different types of forced induction and the pros and cons of each, plus he sheds light on the concept of "intake air density" and how knowing what it is it is more important than knowing what your Boost is. Find out answers to questions like, what is the fuel requirement at a 12/1 air fuel ratio? And if you double your Boost pressure do you double the intake density? Should you go roots or screw? And just what is the worst Supercharger ever made? Watch and find out. This episode is for old school hot rodders, young tuners, and pretty much anyone who isn't satisfied with stock power levels.

Forced Induction: 3D Supercharger Animation
Self-contained ProCharger Superchargers provide the industry's highest efficiency and coolest charge air temperatures. This cool, dense air means more oxygen and fuel for your engine, less exposure to detonation and more power. ProCharger Superchargers utilize natural centrifugal forces to compress air and are not exposed to Exhaust-heat transfer. As a result, they produce cooler air than other designs such as positive displacement Superchargers and turbochargers. Designed and manufactured in the USA, ProCharger models for both street/strip and hardcore racing feature the highest step-up ratio, a patented, self-contained oiling design, exclusive billet impellers, and precision billet gearcases for superior rigidity, sealing and appearance. In addition to higher efficiency and no heat transfer into the blower from heated engine oil, ProCharger's mounting location also places the Supercharger in a fresh air stream, an additional thermal advantage. No heat transfer from an Exhaust interface, nor heat transfer from engine top mounting. Self-contained oiling and this mounting location, together with high efficiency centrifugal compression, combine to produce the coolest operating and charge air temperatures. This high efficiency design also results in optimized fuel economy. With a unique combination of durability and high performance, with years of proven performance on the street and championship-winning performance on the track, self-contained ProChargers are the ultimate power adder. http://www.procharger.com/p1sc-Superchargers.shtml
