KraftWerks Honda K-Series Race Supercharger Kit (C38-91 or 92) ***Built to spec / must drop ship, 150-05-0038K-91/92

The K-Series Race Kit is based off of the impressive Rotrex supercharger. The K-Series Race Kit produces impressive results throughout the entire power band due to its patented traction drive technology. And, unlike any other forced induction system, this kit provides a linear power curve, torque on demand, cooler operating temperatures

The K-Series Race Kit 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 useable 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¢Â€Â™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.

The K-Series Race Kit is built for the hardcore K-Series engine builder. The K-Race kit is designed to mount on the Honda K-Series engine where the A/C compressor was previously mounted. This kit is capable of making +550HP

The K-Series Race Kit fits all K-Series engine blocks. The Race kit includes 3 supercharger brackets and a Rotrex supercharger. This kit does NOT include any type of piping or fuel management.

*Kit REQUIRES Custom Fabrication and Engine Tuning.

*Kit REQUIRES removal of A/C Compressor.

*Kit is NOT CARB Approved, and is never to be used on Pollution Controlled Vehicles or Public Highways.
