Performance Sled Engine Mods

As Wyoming Yamaha riders, we're blessed with what are arguably the smoothest, most reliable engines in the snowmobile industry. We have learned some tricks to boost power on all of our sleds, so hang on and GAS it!


Mountain Performance RX-1, RS Vector & Apex Super Charger
• Easy Install

• Instantaneous Throttle Response





Alpine Motor Sports
RX-1, RS Vector, Apex & Phazer 240-370 HP Turbo Kits

The Turbo kit is designed to give you the best performance possible together with reliability and horsepower that doesn't quit at higher altitudes.







Boondocker Turbo Kits
RX-1, Vector, Apex & Phazer
Boondocker has a new side-mount turbo kit. In this side-mount kit, the stock oil tank is removed and the Garrett turbo is put in its place.
A custom-built aluminum reservoir relocates oil to under the airbox.

• Boondocker says the turbo's location has the benefit of a short exhaust header and charge tube that helps the turbo spool up more quickly.

• The Apex kits use stock injectors and throttle bodies and come with a Boondocker Control Box.
