Go from DNF to the podium with Dynojet’s Stage 5 Power Package.

Our Stage 5 kit has all the features of Stages 1-4, and includes provisions to shed power-robbing heat.

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.

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.

The Dynojet-designed intercooler coolant expansion tank was crafted by Ron Davis and tested in the unforgiving Nevada desert, making the Stage 5 Power Package the most complete solution on the market for peak performance.

Just thank us at the podium!

Leave The R&D To The Pros

How we make it happen

Dynojet’s location in Las Vegas gives us the advantage of testing in brutal desert conditions. No matter where you ride with a Dynojet performance product installed, you’ll know that it’s been pushed to the max before we make it available to you. Stage 5 includes a best-in-class Intercooler Coolant Expansion Tank, giving you an added cooler so you can shed power-robbing heat. For those who crave victory on race day — which includes Dynojet staff — we had to build something to make sure the Polaris keeps running cool. We’re not just engineers and enthusiasts, we’re racers, and we know what it takes to build a vehicle built to win. Months and months of brainstorming, drafting, development and testing went into this Intercooler Coolant Expansion Tank, so you can keep the heat on the competition.
