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.\n\u003c\/p\u003e\n\u003cp\u003e\n  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.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProprietary ECU Reflash:\u003c\/strong\u003e Custom dynamic map reflashed directly onto the factory ECU - no external control boxes, no button pushing.

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.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cdiv class=\"custom-product-faq\"\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need to send in my ECU to get the kit working?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes. 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow long does installation take?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eFor 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat boost level does the kit come set to, and can I adjust it?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eThe 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhich kit should I choose - intercooled or non-intercooled?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eFor 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I put this turbo kit on a sled with high miles?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes, 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan the ECU be reflashed back to stock settings?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes. 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e","brand":"Silber Turbos","offers":[{"title":"Yes \/ Yes - I want my kit ASAP","offer_id":56962603909425,"sku":"sku-40859196883111","price":3750.0,"currency_code":"USD","in_stock":true},{"title":"No \/ Yes - I want my kit ASAP","offer_id":56962603942193,"sku":"sku-40859196948647","price":3250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1724\/7681\/files\/11064824_913114672114693_2051618047936041991_n.jpg?v=1792253014","url":"https:\/\/omahasportsandgames.com\/products\/polaris-axys-rmk-800-ho-turbo-kits-2016","provider":"Omaha Sports \u0026 Games","version":"1.0","type":"link"}
