Product Description

The Kraftwerks Supercharger System for the Honda S2000 from 2004 to 2005 provided huge, consistent power on-demand with no boost lag. Significant power improvements are realized throughout the power band thanks to the same proven frictional planetary-driven supercharger design used in all Kraftwerks systems. At each given RPM, more power when you need it. Additionally, drivability is maintained thanks to a linear power curve and reliable power delivery. The C38-81 supercharger unit included in the package provides a quick throttle response with minimal boost lag or spiking/surging that is prevalent in turbochargers. It also runs cooler and more efficiently than typical forced induction systems because of its unique architecture. Lower intake air temperatures, a cooler air charge, and a lower risk of explosion result as a result of this. The supercharger also has its own dual-action oil pump that moves oil through its own unique oil system. The incorporated air-to-air intercooler further reduces boost charge temperatures for optimal performance, while the external supercharger oil cooler assures proper fluid temperatures.

The modified drive system in this kit improves reliability and maintainability. The previous generation kits' cog drive has been replaced and modified to use a serpentine belt. An automated tensioner is included in the new serpentine drive, making maintenance and replacement easier. All of these qualities add up to greater reliability and efficiency, lower cylinder pressures, less strain on engine components, lower operating temperatures, and power improvements of 60% or more, depending on supporting changes. Ideal for your daily driver or full-fledged motorsport project!
