Mag6240 Posted January 21, 2021 Share Posted January 21, 2021 Running around on same trails the last 3 days, 850 XCR Switchback vs buddies 850 Matryx Launch 137 (not sure it would matter which model), the XCR was consistently running at least 10, and most of the time 15-20 degrees cooler. No scratchers on either sled, same trail, leading or following. What is the difference in the cooling systems besides the rear cooler in the beaver tail of the XCR? Snow flap length?

I'd guess it has something to do with the mapping also. Different mils, right? Out of curiosity, what were the temps on each sled? Quote Link to comment Share on other sites More sharing options...
Guest Posted January 21, 2021 Share Posted January 21, 2021 Same track or different lug heights?? My best guess is the beaver tail cooler was working better in said conditions. Quote Link to comment Share on other sites More sharing options...
Mag6240 Posted January 21, 2021 Author Share Posted January 21, 2021 Both sleds have the 137 1.325 Cobra tracks. XCR would run around 100, 95-108 where the Matryx was around 120, sometimes as high as 130 to 135. Fresh groomed hard pack both sleds would creep another 10-15 degrees.

Doug Posted January 21, 2021 Share Posted January 21, 2021 The XCR with the beaver tail catches more snow and the heat exchanger is right above the rear axle of the suspension where the snow gets thrown. The conversation tunnel has to have more ground clearance on the snowflap as it moves with the chassis and more snow escapes under the snow flap. The XCR snowflap stays at a set distance from the ground cause it moves with the suspension so it does not require as much clearance.

Mag6240 Posted January 22, 2021 Author Share Posted January 22, 2021 As I figured @Doug Just seemed strange that it would be a 15-20 degree difference, in nearly all conditions. Either way, the temps were not anything alarming. Quote Link to comment Share on other sites More sharing options...
