Polaris RZR PRO R 425HP TURNKEY SUPERCHARGER KIT

425 crank horsepower on 91 octane — the 380 system plus the exhaust and intake it wants.

8 PSI | 425 crank HP | 91 octane | Slip-on + dune intake included

• Everything in the 380 kit: Rotrex head unit, billet drive, custom mounts, intercooler package
• Packard 3" slip-on tri-muffler exhaust included
• Pro R supercharger dune intake included
• 425 crank HP on a stock engine, 91 pump gas — factory is 225
• 8 PSI base configuration; OEM drivability retained
• Compressor wheel option lets us size the head unit to your elevation and goals
• One custom tune included

The exhaust and intake aren't accessories on a supercharged car — they're where the last 45 horsepower live. This tier includes both so the system is matched out of the box.

Still 91 octane, still a stock engine. The step to 460 is race fuel; the step to 500 is E50.
