Step up from stock performance and gain up to 40 HP more power with a Stage 4 Power Package. This kit contains the best of both worlds: performance and durability.

Everything you need for epic experiences — or checkered flag glory — is right here in this valuable bundle. Save time and money by getting the Stage 4 Power Package for your Polaris RZR XP Turbo.

We’ve done the hard part for you, developing and bundling these products proven to boost your performance. It starts with our Power Vision 3, packed with premium performance tunes. You’ll also get a Dynojet Clutch Kit, making sure your UTV can handle any terrain and a charge tube made out of durable silicone.

What sets Stage 4 apart, though, is the water-cooled turbocharger upgrade with a Dynojet-designed wastegate actuator. This Big Turbo upgrade allows for 17% more airflow and spools faster, as well as lowers your overall charge temps thanks to an optimized design. Properly tuned with a Power Vision 3, you’ll see a raw power increase of at least 38% on the 2016 Polaris RZR XP Turbo and at least 20% in later models. To ensure boost is delivered and controlled in a consistent manner, we’ve included a Dynojet-designed wastegate actuator, tailor-made for the Polaris RZR XP Turbo.



  • Up to 40 more HP from stock 
  • Water-cooled turbocharger upgrade lowers charge temps
  • Upgraded boost (up to 27 PSI)

Leave The R&D To The Pros

How we make it happen

Good enough,” doesn’t cut it at Dynojet. We know racers don’t want to just finish somewhere in the middle, and enthusiasts aren’t out to have an OK time. We’re constantly looking for ways to deliver more performance and durability, so we upped the ante at Stage 4, which features a turbocharger upgrade. It’s not just about getting vaguely “more power,” it’s about getting up to 40 more HP than stock and pushing everything to the max. In the research and development phase, we’re not afraid to push it ‘til it breaks, and that is most evident in our Stage 4 Power Package. Our tuning experts spent countless hours hand-crafting and testing tunes for the higher boost levels that can be achieved with the upgraded turbocharger you get at Stage 4. Put the hammer all the way down with confidence — that’s how we got here, after all.
