Polaris RZR Pro R

Polaris built it with 225 horsepower. We build it with 380 on pump gas and 500 on E50 — same stock engine, same key, boost mapped to your fuel and your elevation.

225 → 500

One supercharger system and four rungs on it — plus a tune file for the Pro R that isn't ready for boost. The 380 is the kit the 425, 460 and 500 are built on: Rotrex centrifugal head unit, billet drive, custom mounts, high-flow intercooler. What changes going up is fuel, boost and breathing.

          Built to order: Every supercharger kit is built to order and ships in two weeks to a month. Each one depends on a long list of parts, and we only use the best — we won’t source from just anywhere. Demand has been overwhelming, so we’re building as fast as we can, and we’ll be in touch with you through the build and the tune.

          Crank horsepower for the stated kit and fuel. Professional installation strongly recommended. No returns on supercharger kits once shipped.

          What's in the box

          Every bolt, accounted for.

          The 380 comes four ways. The 425, 460 and 500 come one way: complete, with the billet compressor wheel.

          Illustrations highlight selected components and the tuning path. Review the contents and requirements with each kit.

          Stays put
          Fuel

          The tune is written for the fuel.

          Every kit ships with one custom tune. 91, 110 and E50 are different engines as far as the ECU is concerned — so each gets its own file.

          Pulleys & elevation

          Elevation takes boost away.

          Boost by pulley size as published by Packard Performance, at sea level and at 4,000 ft. On the 425, 460 and 500 the billet compressor wheel is sized to your elevation — tell us where you ride.

          How the tune happens

          One trip to Clearfield. Then it's your phone.

          Your ECU beats the kit homePlenums take 7–10 days to build and supercharger kits two weeks to a month, so the flashed ECU usually arrives first. When you order a kit with the tune you pick one: keep your stock tune running with the supercharger tune preloaded — flash it in the HP Tuners app once the kit is installed — or flash the supercharger tune now and leave the machine parked until the kit is on. It won’t run right on the supercharger tune without the kit.
