K&N Air Intake Offers Estimated Boost of 4-HP on 2016 Polaris RZR XP, XP4 Turbo
- 12 May 2017
The company became a major player in the ATV industry when it introduced its Ranger Utility Vehicle (UTV) in 1998. The Ranger featured Polaris exclusive On-Demand six-wheel drive, a rear cargo box and side-by-side seating to accommodate two adults. It became a mainstay vehicle for hunters, farmers, ranchers, and homeowners who work on their land and outdoor enthusiasts who wanted to traverse the rugged off-road terrain for recreation. In 2007, Polaris unveiled the RZR, a UTV meant to challenge Yamaha’s Rhino, which had helped to win a major share of the UTV market for the Japanese manufacturer. The RZR did not only challenge the Rhino, it actually redefined what a UTV was. The vehicle looked different than any other UTV in the market and it was specifically designed to offer off-road fun to riders. The vehicle was only 50-inches in width, which permitted it to go on trails where no previous UTVs could go. Many trails had a maximum width of 50-inches and most UTVs were simply too wide to ride them. It wasn’t long before the RZR was one of the most popular all-terrain vehicles in the market and it helped Polaris become the leading UTV manufacturer. The most recent RZR vehicles to come from Polaris are the 2016 RZR XP Turbo and RZR XP 4 Turbo EPS. A 925cc, 4-stroke, twin cylinder, double overhead twin cam engine with electronic fuel injection powers both the RZR XP 4 Turbo EPS and XP Turbo. The engine delivers 144-horsepower. What’s unique about it is that it delivers the same horsepower at higher elevations. Typically, a UTV engine will lose about 3.0% to 3.5% of its horsepower for every 1000 feet gain in elevation. So, for example, at 7,000 feet, a non-boosted 100-horsepower engine is actually delivering an output power of between 75.5 to 79-horsepower. The Polaris ProStar Turbo engine is not affected by higher elevations because it includes the turbocharger. The engine can achieve 0-60-mph (0-96.6-kph) in 5.89-seconds and offers more than 45% more torque than other engines. In fact, this engine is the most powerful side-by-side engine available. In order to achieve its extreme performance, the engine includes a number of high performance parts including forged pistons, an upgraded 270-degree firing order forged crankshaft, high strength connecting rods, a closed deck cylinder, sodium filled exhaust valves and a new oil lubrication system. It performs consistently in all temperatures because it includes a new liquid charge air cooler with front-mounted radiator and high-flow electric pump. To manage the massive power of the turbocharger, the engine also includes an engine management system with knock detection, boost control and a high-flow return style fuel system. All of this ensures that the engine performs at maximum power in all conditions, altitudes and temperatures.
The RZR XP Turbo EPS also features a suspension system with highly tuned FOX Podium® Internal Bypass Shocks that include large diameter bodies (3-inches/7.6-centimeters in the rear, 2.5-inches/6.4-centimeters up front), adjustable remote reservoirs and increased fluid capacity for dramatic improvement in heat dissipation, fade resistance, and durability. To complement the shocks, Polaris includes bigger coil-over springs. Also included are 29-inch (73.7-centimeter) Maxxis Bighorn tires on 14-inch (35.6-centimeter) cast rims. The vehicle features a 90-inch (228.6-centimeter) wheelbase, 18-inches (45.7-centimeters) of rear travel and 13.5-inches (34.3-centimeters) of ground clearance. K&N has recently introduced the 63-1136 air intake kit specifically for the 2016 Polaris RZR XP 4 Turbo EPS and Polaris RZR XP Turbo. Dyno tests confirm that the kit offers an estimated boost of 4.09-horsepower at 35.8-mph. The kit includes a K&N washable and reusable RU-5064 universal rubber air filter. It features a multilayered cotton gauze media that has been treated with a special grade of oil, which makes the cotton strands very sticky. K&N also offers the 99-5000 filter care service kit that is specially formulated to cleanse and rejuvenate the air filter so that it can be used over and over again for the life of the vehicle. K&N is so sure of the quality of the air filter, it backs it with a 10-Year/Million Mile Limited Warranty. The document promises that the air filter will perform for up to 10 years or 1,000,000 miles without needing replacement. The air filter is totally encased within the air intake kit. The kit also includes a free-flowing aluminum intake tube, nine stainless steel clamps and two couplers. The air intake is designed to dramatically reduce intake restriction because it provides a smoother and straighter path for the airflow to reach the engine. This allows the engine to breathe more air than the factory air intake assembly permitted. The result is a boost in horsepower, acceleration, throttle response, and improved engine sound. The K&N 63-1136 air intake kit can be installed in about 90 minutes using common hand tools. It is designed for the following vehicles: 2017 POLARIS RZR XP TURBO 925 - All Models | |||
