Polaris Xpedition Intercooled Supercharger Kit

150 wheel horsepower on 91 octane from a machine that left the factory with 85. Intercooled, and 12 PSI on E50 if you want more.

8 PSI | 150 WHP | 200 crank HP | 91 octane | 12 PSI on E50

• Rotrex centrifugal supercharger with intercooler and dual electric fans
• Bracket system, drive pulley and belt, charge piping — all machined and fitted to the Xpedition
• Bosch 1000cc injectors and 3-bar MAP sensor
• Secondary clutch helix and spring so the driveline keeps up
• Base tune for 91 octane (8 PSI) or E50 (12 PSI) — your choice at checkout
• Fits XP5 and ADV5
• Builder kit, base kit with tune and ECU unlock, or complete kit with the flashing device

The Rotrex builds boost with RPM, so the machine idles, crawls, tows and cruises exactly like an Xpedition. Then you open it up and it's 150 at the wheels instead of 85.

The intercooler is what makes the E50 map possible — cooler charge air is how it runs 12 PSI without heat soak on a long pull.
