Trail Boost Performance Kit (Stage 3) 13-311-3
Stage 3: The Big Mo Turbo—Maximum Power and Dominance
The Stage 3 Kit is the ultimate performance package for the Polaris Patriot Boost. This kit includes all the essential, proven airflow and drivetrain components from Stage 2, but elevates performance dramatically with the heart of the system: our custom "Big Mo" Turbocharger.
This complete upgrade is engineered to deliver the largest gains in horsepower, torque, and track speed possible. By combining the Big Mo Turbo with the optimized airflow path (Manifold/Y-pipe, Charge Tubes, and BIG Air Intake), your machine will dominate any terrain and provide massive "turbo smiles."
NEW Stage 3 Component for Extreme Power:
- Custom "Big Mo" Turbocharger: The centerpiece of this kit. This upgraded turbo is designed for maximum flow and sustained boost, delivering significantly higher horsepower gains across all fuel types. The Big Mo also decreases intake charge temperatures, leading to more power and longer engine and turbo life.
Stage 3 Core Performance Features (Includes all Stage 2 Components):
- Maximum Power and Tuning: Every kit includes your choice of engine tuning: either an ECU Hard Flash (you send in your ECU for us to flash) or a Torque Link license. The Big Mo Turbo adds approximately 10 HP more than the stock turbo on any equivalent tune level.
- On-Demand Performance: Instantly select your desired power level using the 7S gauge. Choose from quick spool options for improved throttle response, or boost power by 10+ HP to 20 HP on pump gas with the press of a button.
- Maximum Gains: Unlock race-fuel potential like never before: achieve 50+ HP on 100 Octane or an incredible 80+ HP on Q116 Race Fuel.
- Drivetrain Optimization: The included Stage 2 SNYPR Clutch Kit and Cyclone Clutch Cover deliver faster acceleration, a more responsive machine, and a critical 30+ degree reduction in belt temperatures.
- Airflow & Exhaust Optimization: Includes the Performance Manifold/Y-pipe, High-Flow Charge Tubes, and BIG Air Intake for the most efficient air delivery possible, paired with your choice of high-performance muffler.

Your choice of a Torque Link flashing device or a "hard flash" ECU tune
Your Choice of Tuning: ECU Hard Flash or Torque Link
ECU Hard Flash: The Mail-In Option
If you select the ECU Hard Flash, you will need to fill out a work order form and ship your vehicle’s ECU directly to us. Once we receive your ECU, our typical turnaround time for flashing is 1–2 business days, plus return transit time (standard UPS Ground). You are responsible for shipping to us, but we cover return shipping. This is a reliable option for those who don't mind the brief downtime.
Torque Link: The Convenient Flashing Device
Our Torque Link flashing device offers maximum convenience: it allows you to tune your ECU without the hassle of mailing it in. Simply log on to the Torque Link platform to create an account, then contact us to activate your tuning license. A key benefit of Torque Link is gaining access to all available tune levels for your vehicle through the app at no extra charge, allowing you to instantly switch performance maps as your needs change.
Important Tuning Notes:
- 2025 model year is a single stage tune only.
- Do not update 7S screen from Polaris, you will lose your 3 tune choices on the dash. Update through the Torque Link website.
- If you choose the Torque Link, you must purchase the Flasher Box separately.
Comparison of Bikeman Boost High-Performance Exhausts:
We offer three distinct Boost exhaust systems, each designed to meet specific performance and sound preferences.
-
Race Exhaust: The loudest and most aggressive choice, maximizing both performance (with HP gains and improved turbo spool without a tune) and weight savings, shedding a substantial 10.2 lbs (5 lbs total weight); however, it is strictly for off-trail use due to its noise level.
-
Stainless Steel Exhaust: This exhaust balances performance, weight, and material cost, still offering a significant 7.2 lbs weight savings (8 lbs total weight) and being necessary for tuned sleds, but like the Race option, it does NOT meet Trail Decibel requirements.
-
The Titanium Exhaust: The premium, lightweight option, offering near-race-level weight reduction at 10 lbs savings (5.5 lbs total weight) and being a "must-have" for tuned sleds, while providing performance-enhancing turbo spool and response.
