Aerocharger 66 Series

VATN Technology

Aerocharger's powerful variable geometry tech optimizes turbine size, producing lag-free boost. Excellent performance for high altitude and technical riding. The ideal turbo for 2-strokes.


Independent Oil Supply

The Aerocharger contains it's own oil supply allowing for clean and simple installation, and reduced risk of complications when riding.


Non-Flooded Bearings

Innovative oil misting system allows for drag free bearing performance and ultra-fast spooling. A major performance increase over conventional journal bearings.


Welded Turbine Inlet

Aerochargers for Ski-Doo snowmobiles now feature welded turbine inlets, which reduce weight and back-pressure while improving flow to the turbo.


Air Box

Durably Built

Robust design allows for best air flow from the turbo. Stainless Steel construction, finished with bake-on ceramic coating.


Tuned Backwall

Designed to correctly reflect acoustic waves from the E-TEC intake, maintaining stock engine system efficiency that are critical to the E-TECs performance.


Turbo Optimized

Correctly shaped to provide optimal air volume to the Aerocharged E-TEC engine.


Snow to Air Intercooler

Harness The Cold

The most effective intercooler ever made for a snowmobile. This performance upgrade is an intercooled airbox that rapidly cools the air charge from the turbo by directing water, snow and ice from the tunnel through the intercooler core. This intercooled airbox installs into the Ski-Doo tunnel, requiring moderate modification to the tunnel. Testing shows that this intercooler provides a more consistent heat-sink than traditional Air-Air ICs, and is significantly more engine-friendly than Air-to-Water setups. The air charge is being cooled as soon as the track is moving, without putting any additional load on the engine, coolant and electrical systems.


Competition-Grade Equipment

Aerocharger developed this intercooler to give our riders a competitive edge on race day. It proved to be extremely effective, and has now been made an option at the consumer level.



Stainless Steel Exhaust

Flow-Through Design

This muffler has been sized to flow exhaust from the turbo quickly and effectively.

TIG Welded

Durable construction by skilled production welders. Stainless Steel construction finished with ceramic coating.

Optimized Exit Angle

The front facing departure avoids blockage by trailing the snowmobile's A-Arms. This placement was tested by top back-country riders, who found this to be the most effective setup.



Best Performance

An extensive clutch setup is included in our Standard Non Intercooled and Air to Snow Kit,specifically configured for best operation on Aerocharged Ski-Doo snowmobiles.


Full Setup

Includes a dual-angle helix that can be set for racing performance or back-country conditions. Also comes with custom ramps, adjustable tungsten weights, primary spring, an alternate top gear, chain and oil, and Aerocharger's recommended settings based on boost and altitude.



Fuel Management

Exclusive Fuel Programming

The Aerocommander fuel controller is pre-mapped with a proprietary program to fully optimize the Aerocharger's performance with the E-TEC. Maps are updated annually for improved performance. The Aerocommander is fully plug-and-play right out of the box.

Sequential Injection

Sequential injection improves fuel injection to enhance throttle response.

External MAP Sensor

The fuel controller hardware now includes an external three-bar manifold absolute pressure sensor. An external sensor provides an improved reading for smooth fueling, and makes the Aerocommander unit 100% water proof. Comes with a 2 Year Warranty.


Also Included with the Non Intercooled System and Air to Snow System


Custom Charge Tube

Silicone Construction - lightweight and durable for high pressurization.


Guage Panel

Innovate AFR Gauge and Custom Boost Gauges are included.


Stinger Kit

Parts and instructions are included to modify the stock pipe with an Aerocharger stinger. This pipe is larger in diameter and improves exhaust flow for better performance. Will require cutting and welding the stock pipe.


Turbo Reeds

Upgraded turbo reeds are provided with every Aerocharger E-TEC system. Developed by BRP based on use with Aerocharged E-TECs, these reeds are more robust and have a longer life during turbocharged use.


Heat Shield

Ceramic Coated stainless steel for best thermal control.


Dome Filter

Stainless steel mesh intake screen filter.


Vent Kit

Heat dissipation is critical for best turbo performance. 7 Snow Silk vents are included, with templates and instructions for easy installation. An Advanced Snow Silk Ski-Doo vent package is available in the Upgrade section.
