The trouble with adding power to a snowmobile engine is that it usually comes with a bit of undependability. And the last thing you want to do is to fight with an engine when you have a foot of fresh powder beckoning to you.
So last winter when the editors of SnoWest were looking to add power to their Ski-Doo Summit 800 project sled, it was important to find something reliable. And there are not too many big bore kits more reliable than the Trygstad 872cc Etec kit.
For eight years Trygstad Motorsports have been fine-tuning the 872 kit and have countless hours of testing to make the kit bullet-proof for everyday riding.
The Trygstad 872 creates between 186-190 horsepower with a huge torque band. It can be designed for either pump fuel or race fuel blends. The kit retails for $1,950. For more information contact www.trygstad-motorsports.com.
