olaris Xpedition Rotrex Supercharger Kit
5 PSI | 130 WHP | 175 Crank HP | 91 Octane
Turn your Polaris Xpedition into the machine it should’ve been from the factory.
This custom supercharger kit is built around a Rotrex centrifugal supercharger, delivering a clean, reliable 5 PSI of boost and producing approximately 130 wheel horsepower (WHP) — up from 85 WHP stock — all while running 91-octane pump gas.
That’s a serious bump in power while keeping drivability smooth, predictable, and trail-ready.
