On the Bench
The 600 HO should be a rocket ship in the 600 class. Ski-Doo said it aimed at the class benchmark (Polaris) when it designed this engine. By our testing, it surpassed the Liberty twin by a couple of horsepower. We knew it was a strong runner in our on-snow testing last spring, but we didn't know how strong it really was.
We found 119.8hp at 7800 rpm, with the torque peak of 80.6 pounds right on top of it. "This is an impresive engine package," noted Dynoport's Rich Daly. "The 600 HO very makes good power for its size. It does it on a cold pull and then holds it on successive runs."
Our contacts at Ski-Doo were quite pleased with the results of our 600 HO test session. They indicated that it fell cleanly within the range of variation between production engines and dynos.
"This is a strong motor," Daly concluded in his test notes. "It runs at very low RPM and makes high torque. It should be good on the trail and easy to clutch with its good torque."
