Description from Packard Performance:

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.

Performance

• ~130 WHP at 5 PSI

• 175 HP at the crank

• Strong midrange torque

• Smooth, linear boost curve

• OEM-like drivability with significantly more power

The Rotrex system builds boost progressively, giving you controllable power whether you’re crawling tight trails or wide-open in the desert.

Factory Output vs. Supercharged Setup

That’s:

• +45 wheel horsepower

• +61 crank horsepower

• ~53% increase at the wheels

You’re not just adding a little pep — you’re transforming the machine:

• Faster acceleration

• Stronger midrange pull

• Higher top-end speed

• More responsive throttle

The beauty of the Rotrex centrifugal supercharger is how it delivers that power — smooth, progressive boost that feels OEM but hits substantially harder.
