Road and track proven over eight years the BBR supercharged conversion is based upon the Rotrex C30-94 Centrifugal design with superior efficiency, silent operation and self contained oiling system, combined with it’s unique patented traction drive technology it offers the smoothest linear power delivery. The supercharger supplies airflow of up to 0.39kg/s reaching impeller speeds of up to 100,000RPM combining small size with exceptional performance & durability. The BBR Supercharger kit's true strength lies in exploiting the exceptional balance and poise the chassis has from the factory. Retaining the car's OEM smooth, linear power delivery characteristics, with no spikes in torque are in keeping with the MX5's character.

By using the original manifold back exhaust system the BBR Stage One Mazda MX-5 MK3/3.5/3.75 supercharger conversion produces a discrete, quiet performance.
