Track's...fully clipped, all open windows.....

When starting both my sleds before heading out, I find it interesting that the Vec heats up quite a bit faster than the Rage. Of course there's a slightly longer set of heat exchangers on the long track, but it's strange.

Unless, of course there might be a different mix in the two systems?

Now I know that the antifreeze and proper water mix will raise the boil point and lower the freezing point, but does it really change the ease of heating?

The diff on the two sleds is almost like the water pumps are moving the water at different speeds as the Vec can be hot to the touch (maybe 135) vs the Rage being warm, maybe 105 degrees.
 
A higher glycol concentration mix will not transfer heat as efficiently as a lower concentration mix and consequently the higher concentration mix sled will heat up faster and run hotter.
