Nerdy Engine video from Koenigsegg


Recommended Posts

Only as it pertains to the Rotax 2-stroke engines. They used rotary valves in their snowmobile engines and a lot of their aircraft engine applications, I believe. They seemed to work fine, but I believe they have gone back to the more conventional reed valves in their sled engines...but don't quote me on that. I was never much of a Ski-Doo fan...! I'm more of a Polaris Pro and Arctic Cat M-chassis fan...and I've always run V-Force reeds in my sleds.
