Aerocharger co-developed the Ski-Doo E-TEC turbo system with BRP Racing starting in 2009 for RMSHA, and the Aerocharger was the first working kit available at the E-TECs release in 2011. BRP Racing dyno’d the Aerocharger system and registered 240hp at only 7psi, and this system can be set to produce a range of 200-300hp. This system was designed in close collaboration with BRP Racing, who contributed design criteria and system specifications to ensure that a properly designed aftermarket turbo kit would be available for the E-TEC snowmobiles. The Aerocharger is a substantial innovation over conventional turbocharger technology, making it ideal for use with Rotax 2-stroke engines. The Aerocharger E-TEC system was built to prioritize horsepower-generating efficiency, and this equals an ultra-responsive, ridable system that excels at high altitude and on technical terrain.

We strive to provide the most comprehensive package possible right out of the box, and this season we are improving on it with a few refinements.

2015 Ski-Doo Freeride Turbo - Aerocharger turbo system at Action Motorsports in Gillette, WY.

  • WEIGHT REDUCTION. Whether climbing, side hilling or just getting unstuck from the deep stuff, mountain riders understand that every ounce makes a difference. Last year’s Aerocharger system totaled out to an overall sled weight reduction of -2 pounds, making it the lightest kit available industry-wide. For 2013, weight reduction will be further improved to -6 pounds.
  • SLED VENTING. Heat dissipation is critical for best turbo performance, so we went ahead and included turbo side and clutch side Snow Silk vent kits in every Aerocharger snowmobile turbo package this season.
  • CLUTCHING. Clutch setups were the most requested item last season. Getting this right is one of the biggest factors in your turbo sled running the best it can, and this year an extensive custom clutch setup comes standard in every Aerocharger snowmobile turbo system. This includes custom ramps, weights, gearing, and a very cool custom helix with improved angles for turbocharged operation.

System Specs

Performance Gains

BRP Racing dyno’d the Aerocharger E-TEC 800 system, and registered 240 hp at 7psi boost. The average Aerocharger is set at 7psi boost.


For best performance, Aerocharger recommends using a minimum of 100 octane fuel when running this system. Pump gas not be used under 7000 foot elevation. A pump gas option is in development, and more information will be available later in the season season.

This fuel guide lists recommended octane levels based on boost and altitude. This chart is for reference only – many factors affect safe octane such as air density, temperature, and tolerance specific to your motor. This chart is intended to suggest rough guidelines based on the most common operating environments.

Boost Levels

Max boost level is mechanically set by a pre-loaded spring inside the Aerocharger’s integrated boost controller, and aftermarket boost controllers can also be used for additional boost control. See the Aerocharger page for additional information.

An Intercooler is recommended for E-TECs set at boost levels higher than 7psi. Exclusively for the Aerocharger E-TEC System, an innovative new Snow-to-Air Intercooler is available as an option for a consistently cooler air charge. Click the upgrade tab to read more about the Snow-to-Air Intercooler.

Big Bore/Compression Mods

The Aerocharger E-TEC System is compatible with engine mods such as big bore kits or lower/higher compression.

Reliability & Support

Aerocharger has a well-tested, strong-running and reliable turbo system. The Aerocharger doesn’t require any more care or maintenance than any other turbocharger, and when properly installed your Aerocharger system should outlast the life of your sled. We will make sure you have the support you need – for any questions, troubleshooting or maintenance, don’t hesitate to directly contact Aerocharger’s engineers or your nearest Aerocharger dealer.


Aerocharger systems are designed so they can be installed at home by a rider with moderate mechanical ability and common garage tools, but many Aerocharger customers prefer to have their turbo system installed at a dealership or performance shop. Dealers report prefering Aerocharger technology because Aerocharger systems are properly designed and either simplify or eliminate many fail-prone components, thereby requiring much less support and maintenance.

Contact Aerocharger for information about dealers in your area.
