MAXIMUM POWER ACHIEVED THROUGH AIR INTAKE, ACCELERATION AND DISTRIBUTION
BOYESEN engineers embarked on a mission to create a new lineage of aerodynamic intake technology by refining the primary performance factors required to increase peak horsepower through design innovation: Aerodynamic Surface Optimization, Model-Specific Reed Petal Tensioning, Material Fuel Resistance, and Multi-Stage Reed Timing. Together, these innovations create a new technological benchmark in intake performance. The next generation Rage Cage RC2 series results in an optimized reed valve system that provides superior efficiency, peak horsepower gains, and acceleration for YOUR specific model sled.
Your engine is a glutton for air. It will take over 200 "gulps" per second, at velocities over 500 MPH - if your intake valve will let it. The Rage Cage's seamless, one-piece, precision casting and continuous aeroform surfaces ensure maximum flow velocities and instant, explosive movement of air particles the moment you open the throttle. Result: An intake valve the size of your fist delivers air with the power of a tornado.
POWER CHANNELED AIR CHARGE
Integrated into the seamless inner chamber are 4-way aerodynamic directional dividers that distribute the angled charge evenly without flow loss. Each channel has its own unique Power Profile, scientifically shaped to produce instant, explosive movements of air. Result: Unparalleled performance.
INTELLIGENT MULTI-STAGE REED PETAL SYSTEM
Standard equipment on each Rage Cage, Boyesen dual-stage, Pro Series Reeds have the superior ability to time themselves to the needs of the engine. You get maximum flow velocity across the entire RPM range, and at all throttle settings. Smooth. Sharp. Smart. Result: Full Spectrum power and throttle response.
OPTIMIZED FOR EACH MAKE/MODEL/YEAR SLEDl
Each Boyesen Rage Cage is unique - tailor made to that model, year and displacement. While other aftermarket valves might change flange sizes or bolt patterns, they’re basically generic - and require you to irreversibly cut your intake boot to install it! But with the Rage Cage, there are no compromises in power, no modifications. Result: A true, bolt-on Power Boost.
RC2 Series Performance Features
AERO OPTIMIZED INTERNAL SURFACING
The ONLY performance system with aerodynamic internal surfacing.
Internal precision surfacing treatment eliminates all hard edges that interrupt with the proper delivery of air and fuel. Because internal air turbulance is virtually non-existent, the proper air/fuel control is optimized for each make/model/year sled. This attention to the speciic air and fuel requirements of each sled gives the RC2 Series Rage Cages the ability to reach consistent peak horsepower gains, optimizing power delivery for each specific application.
XCROSS DUAL CARBON WEAVE
Model-Specific variable tension reed petals.
The Rage Cage’s Multi-Staged reed petal stacks feature Aerospace carbon material interwoven into tension combinations that maximize power delivery and peak horsepower. Boyesen engineers specifically tune the carbon matrix tension using a proprietary weave formula that is tested and optimized for each model sled.
The most durable materials. The most lifespan.
The RC2 Series Rage Cage now features category-leading toughening additives to increase reed petal lifespan by resisting breakdown from damaging agents found in fuel. In addition to our proprietary T2 Epoxy, the Rage Cage features rubber coated reed petals to ensure a long-lasting seal between the petals and the intake tract time and time again. Your customers will enjoy the durability of the Rage Cage season after season.
MS PLUS FLOW OPTIMIZATION
One reed petal is NOT enough!
The reed petals in modern snowmobile engines take an incredicle amount of abuse! At peak RPM reed petals are opening and closing hundreds of times per second. Over time, a single reed loses its ability to regulate flow rates in proper proportions. This causes a loss of reed petal reaction and reduces the consistency of peak horsepower. MS PLUS Optimization uses multi-staged reed petals to distribute the engine’s pulse forces over more surface area. By using a multiple reed petal stack, it is possible to acheive peak horsepower AND durability. The patented multi-stage design incorporates a specially shaped top reed petal and a ported bottom reed petal. The top petal is lightweight and resilient for crisp throttle response at partial throttle or low RPMs. The stiffer, bottom petal is ported to provide maximum flow and horsepower at higher RPMs.
SUPER NITRILE BOOT
The most durable materials. The most lifespan.
Boyesen's proprietary rubber component compounds provide protection from extreme external temperatures. In addition to the longevity against external temperatures, our rubber compounds resist deterioration from caustic fuels that have been proven to breakdown rubber material of other air boots.
