Polaris Axys RMK 800 HO Turbo Kits 2016+


Description

The Silber Turbo Axys RMK 800 HO Turbo Kit is a complete, bolt-on forced induction system engineered specifically for 2016 and newer Polaris Axys RMK 800 HO sleds. Developed over multiple seasons of real-world testing alongside Polaris factory riders, this kit delivers fast throttle response across the entire RPM range and enough power to satisfy the most demanding riders on the mountain. The no-cut installation design means you won't be modifying your tunnel, belly pan, or hood - just bolt it on and ride.

At the core of this kit is Silber's proprietary ECU reflash technology - a dynamic, custom map that automatically adjusts fueling parameters for changes in elevation, temperature, and boost without any rider input. Whether you're charging steep technical lines or blasting through open powder fields, this system adapts on the fly so you can focus on riding. Available in two configurations - standard non-intercooled and premium water-to-air intercooled - there's a build level for every riding style and boost target.


Key Features

  • Proprietary ECU Reflash: Custom dynamic map reflashed directly onto the factory ECU - no external control boxes, no button pushing. Automatically adjusts fueling for elevation, temperature, snow conditions, and boost level.
  • External Wastegate Ceramic Ball Bearing Turbo: Purpose-built for the 800cc two-stroke engine. Spools quickly and smoothly, and maintains boost pressure efficiently during on/off throttle transitions in technical terrain.
  • Adjustable Boost (3-12 psi): Swap wastegate actuator springs to dial in your preferred boost level. Kit ships preset with a 7psi spring; 3psi and 5psi springs also included for easy adjustment.
  • No-Cut Installation: Designed to install without any permanent modification to the sled. Experienced riders have completed the full install in under 2 hours including clutching.
  • 304 Stainless Steel Polished Exhaust: Performance-oriented exhaust system constructed of 304 SS, fully polished, and designed to exit at the OEM belly pan location for a clean, factory-style finish.
  • Custom Molded Silicone Charge Tube: Smooth-flowing silicone construction resists heat transfer, unlike aluminum, and provides an OEM-quality fit between turbo and engine.
  • Cold Air Intake: Lightweight, high-impact modular plastic intake routes air from the stock hood vents directly to the turbocharger, utilizing cold outside air for maximum charge density.
  • Exclusive Oil Pump Tuning: Silber is the only turbo kit manufacturer with the capability to increase oil pump output via their proprietary tuning software - ensuring proper engine lubrication under boosted conditions regardless of altitude.
  • Recirculating BOV: Blow-off valve is plumbed to recirculate, keeping the turbo spooled and maintaining consistent boost response, especially in tight trees and technical mountain terrain.
  • Intercooled Option Available: The intercooled kit uses a water-jacketed turbo compressor cover and a custom billet aluminum heat exchanger cooled by the factory coolant system, replacing the OEM bulkhead plate for a seamless fit.

Kit Options & Which to Choose

  • Non-Intercooled: The most popular choice. Performs exceptionally well from 3-7psi with some riders running up to 10psi. Simpler install, excellent throttle response, and ideal for the vast majority of mountain and backcountry riders who want serious power without the complexity of a separate cooling circuit.
  • Intercooled: The premium build for riders who want to push boost beyond 10psi, run full race fuel, or ride in the most extreme high-output environments. Features a standalone water-to-air intercooling system with a custom billet aluminum heat exchanger and water-jacketed compressor cover. Best suited for advanced riders seeking the absolute lowest charge air temps and maximum power potential.

What's Included

  • External wastegate ceramic ball bearing turbocharger
  • Recirculating blow-off valve (BOV)
  • Custom proprietary ECU reflash (requires sending in your stock ECU)
  • 304 stainless steel polished exhaust system
  • Custom molded silicone charge tube
  • High-impact modular plastic cold air intake
  • Wastegate actuator spring preset to 7psi
  • 3psi and 5psi wastegate actuator springs
  • Wastegate spring swap tool
  • Intercooler kit (intercooled variant): custom billet aluminum heat exchanger, water-jacketed turbo compressor cover, and associated coolant plumbing
  • All hardware and components needed for a complete, ride-ready installation

Why You'll Love It

Silber Turbo has been at the forefront of snowmobile forced induction since the early development days of the Axys platform, and the RMK 800 HO kit is the result of years of field testing, factory collaboration, and continuous refinement. With hundreds of kits running on snow across the country, this is a proven system trusted by serious mountain riders everywhere. The no-cut design means your sled stays stock-reversible, and the OEM-fit exhaust and intake components give it a clean, purpose-built look rather than a cobbled-together appearance. Silber's exclusive oil pump tuning capability is a genuine differentiator - it's the kind of engine protection engineering that separates a thoughtfully engineered turbo system from a bolt-on boost kit. Whether you're a weekend warrior looking for more pull out of the gate or a hard-charging backcountry rider pushing the limits of the 800 CFI motor, this kit delivers performance, reliability, and real-world value that stands up to anything else on the market.


Do I need to send in my ECU to get the kit working?

Yes. Your stock ECU needs to be sent to Silber so they can reflash it with the custom dynamic map specific to this turbo kit. This reflash is what makes the system work reliably - it replaces the need for external control boxes and allows the engine to automatically adjust fueling for elevation, temperature, and boost changes without any rider input. Instructions for shipping your ECU are included with your order.

How long does installation take?

For riders familiar with snowmobiles, expect 3-5 hours for a complete and proper installation. Some experienced customers have completed the install in under an hour. The no-cut design means no permanent modifications are required, making the process straightforward for any mechanically inclined sled owner.

What boost level does the kit come set to, and can I adjust it?

The kit ships preset with a 7psi wastegate actuator spring. Included with the kit are 3psi and 5psi springs, allowing you to tune your boost level anywhere from 3-12psi by simply swapping springs with the included tool. Going above 10psi on the intercooled kit is possible, though riders pushing 12psi or more may need to contact Silber about larger injectors and a custom map.

Which kit should I choose - intercooled or non-intercooled?

For most riders, the non-intercooled kit is the right choice. It performs extremely well from 3-7psi and handles up to 10psi without issue. The intercooled kit is designed for riders who want to run full race fuel, push boost above 10psi, or ride in the most extreme high-output conditions where the lowest possible charge air temperatures matter. If you're unsure, the non-intercooled kit is where the majority of Silber customers land - and they love it.

Can I put this turbo kit on a sled with high miles?

Yes, but it's important to make sure your engine is in good health before adding boost. Before installing, verify that compression is within spec, clean your exhaust valves, and inspect your reeds to make sure they're in good shape. A turbo kit will amplify both the performance and any underlying issues of the base engine, so starting with a healthy motor is key to a reliable setup.

Can the ECU be reflashed back to stock settings?

Yes. The ECU can be reflashed back to the original factory tune if needed. This means the modification is reversible, which is a benefit for riders who may want to return their sled to stock at any point.
