Packard Performance Supercharger Kit for Polaris Xpedition MT

Description

Packard Performance Polaris Xpedition MT Supercharger kit

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

• ~130 WHP at 5 PSI
• 175 HP at the crank
• Strong midrange torque
• Smooth, linear boost curve
• OEM-like drivability with significantly more power

Features:

• Conservative 5 PSI configuration
• Designed for stock internal engines
• Proper belt alignment and bracket rigidity
• 91-octane pump gas compatible

Specifications:

• +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.
