The Kraftwerks Honda B Series "Race" Kit is built for the hardcore B engine builder.

Centered around the highly efficient Rotrex C30-94 Supercharger, the Kraftwerks Supercharger kit produces impressive results throughout the entire power band. While unlike any other forced induction system, the Kraftwerks supercharger system provides a linear power curve, torque on demand, cooler operating temperatures, and total drivability. The Kraftwerks supercharger system provides instant throttle response and a progressive power curve that increases all the way to redline without the typical 'spiking' or 'surging' associated with turbochargers. This unique, more usable power curve results in reduced cylinder pressures, less strain on engine components, and increased reliability.

Rotrex superchargers also operate much cooler when compared to turbochargers and other supercharger systems, which reduces the engine's intake air temperature as well as its risk of detonation. Rotrex superchargers are renowned for their compact size, high adiabatic efficiency, low vibration, and quiet operation. Their unique traction drive technology is what makes all of this possible, which, unlike other superchargers, transmits power through frictional forces between its rolling elements. Each Rotrex unit features its own self-contained oiling system that remains independent of the engine. Its dual-action oil pump supplies traction fluid to the supercharger while the supplied cooler ensures proper fluid temperatures at all times.

Kraftwerks has designed the billet aluminum brackets to mount the C30 line of changers. The bracketry is designed to mount the head unit low on the motor in a similar position to that of the OEM A/C compressor. The kit requires the installer to fabricate the supercharger inlet pipe, charge pipes, and intercooler as well as provide all necessary support parts and tuning. Fits B16A, B17A, B18A, B18B, B18C, B20A, and B20Z
