For the ultimate in performance and looks, our line of Billet machined heads for the Polaris AXYS 850 (Patriot) are the answer to the highest performance as well as pump-gas operation! The Idaho™, purpose built for pump gas, and The Colorado™ which has been optimized for high-octane, high boost.

Both heads offer a ruggedized, through-bolt construction from aerospace-grade aluminum, maximized cooling potential, and the top-tier driveability and consistency that BoonDocker customers have come to expect. We’ve ridden the pump-gas setup, including The Idaho™, and can attest that this is pump-gas perfection.

Summary

THE IDAHO™: For BoonDocker turbocharged Polaris Patriot owners, The Idaho head from BoonDocker is the solution to pump gas performance among all aftermarket turbo kits because we’ve strategically engineered a combustion chamber that fully leverages the potential power of the turbocharger kit, at all RPM’s and riding conditions, provides more predictability and control of tuning, while incorporating a ruggedized design and bill-of-materials, specific to the higher demands of a turbocharged engine.

THE COLORADO™: For BoonDocker turbocharged Polaris Patriot owners looking for the ultimate in high-octane power delivery, The Colorado™ head from BoonDocker provides both increased performance and strength over the stock head because The Colorado’s™ combustion chamber has been optimized for the demands of high-boost, high-octane, while providing additional horsepower and control and predicitbility of tuning, over the stock head.

NOTE: The Colorado head also has an application for pump-gas above 8,500 feet. Read more in the FAQ's

Stats and Specs

• Bolt-through, bonded design: promotes uniform performance, and prevents dome-walk or head-movement. A single piece of billet aluminum spans both cylinders for maximum precision and performance.
• Turbo-tough: Billet heads have been specifically designed and reinforced for maximum durability and longevity
• Maximized cooling efficiency: We’ve engineered industry-leading cooling technology and flow. This head is the premiere choice for turbo-owners.
• Optimized for turbo performance: purpose-specific engineering of the combustion chamber leverages the turbocharger to create pump-gas performance, at every RPM, that is ON-PAR with previous 50/50 performance.
• Optimized for pump gas: The Idaho™ has been specifically calibrated using 91-octane, with up to 10% ethanol. This fuel is readily available for our customers, and gets BoonDocker back to our mission of pull-and-go, pump gas power!
• CLUTCHING NOT INCLUDED: Clutching purchased separately (REQUIRED)

Suggested Upgrades

• Agility Intercooler:
• While it's best to buy the intercooler when you buy the kit, our Agility Intercooler is available as an upgrade
• Clutching:
• We STRONGLY suggest our BoonDocker High Energy ™ clutching.
• Base Kits: For low-boost, high-elevation only
• Premium Kits: suggested for all applications
• Actuators: 
• Blue: 4-8 PSI (max 8.4), comes standard with kit
• Black: 6-10 PSI (max 11.2), required for high-boost. Will increase throttle response and produces a more powerful seat-of-the-pants feeling, even on lower-boost kits. All things equal, upgrading your actuator will increase the octane requirement
• Double-Black: 8-12 PSI suggested only for seasoned mod-sled builders. All things equal, upgrading your actuator will increase the octane requirement
