    SPRINTEX S5 Series

    The Sprintex supercharger is a positive displacement, mechanically driven twin screw type compressor. Its unique, patented rotor profile design exhibits minimal internal leakage and has low parasitic losses.

    The patented Sprintex rotor design, coupled with its tight internal clearances provide excellent efficiency and minimal leakage at all operating speeds resulting in superior all round performance.

    The power increase on a Sprintex equipped engine is linear, with an instant throttle response and no lag. Significant torque gains are achieved at low engine speed and are maintained throughout the operating range of the engine. Sprintex superchargers are compatible with most fuels and engine cycles and application flexibility.
