Polaris RZR PRO R 380HP TURNKEY SUPERCHARGER KIT

380 crank horsepower on a bone-stock Pro R engine, on 91 octane. The factory number is 225.

8 PSI | 380 crank HP | 91 octane | Stock engine

• Rotrex centrifugal supercharger head unit — boost builds with RPM, so the car still drives like a Pro R at part throttle
• Billet drive assembly and custom mounting system, machined in Clearfield
• High-flow intercooler package
• 8 PSI base configuration on pump 91; OEM drivability retained
• 380 crank HP on a 100% stock engine — up from 225
• Grows with you: the same system carries 550+ HP and 22+ PSI with supporting mods
• One custom tune included. Additional fuel tunes are $200

This is the kit the 425, 460 and 500 tiers are built on. Bolt it on, run the included 91 tune, and the car makes 155 more horsepower than it did this morning without touching the bottom end.

When you want more, you don't buy a new kit. You add the slip-on and dune intake for 425, race fuel for 460, E50 for 500. The hardware stays.

Pick the kit option that matches how much of the install you're doing yourself. Written and video install guides are on the site.
