These long awaited superchargers are finally here. This tip to toe kit includes everything you will need to complete the install. The installation itself is more of a one day type of thing. There are 100% reversible and requires no permanent modifications to your car. You do not need to cut or tap anything. Installation can go as quickly as 4 hours. These centrifugal supercharger systems really gives your car a new life. They are now ready to hold it’s on, even on the straight ways. Let us know if you are interested in one. We would gladly answer questions that you may have. 

This kit includes everything from Injectors to fuel pump.
Like all KraftWerks supercharger kits, Miata systems are based off of the impressive Rotrex supercharger and include everything necessary for a truly bolt-on installation.
At the heart of each KraftWerks Miata kit is the Rotrex C30-74 centrifugal supercharger. Rotrex’s patented traction drive technology works unlike any other supercharger, and means that power’s always available, all the way to redline. Results may vary depending on your car.
Each Miata supercharger system is a comprehensive design and includes all necessary components to ensure safe, reliable operation. Standard-issue with each kit is a large, front-mount intercooler to help ensure low intake air temperatures for optimal performance. All necessary aluminum tubing, silicone couplers, and clamps are also included for easy installation. Proper air/fuel ratios are ensured with the included Grams Performance fuel injectors, Grams fuel pump, and boost-dependent fuel management unit. Convenient, plug-and-play fuel injector adapters are also included, making each kit a true bolt-on experience.
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 KraftWerks Miata supercharger system provides instant throttle response and a progressive power curve that increases all the way to redline without the typical spiking or surging turbochargers are known for. 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’s intake air temperature as well as its risk of detonation.
