Uhhhh it's a Everyday sled with a slighty shorter cooler. Nothing too racing about it.
HCR minus rear cooler

yes there is, Graphics that say HCR.

Some may not know but the HCR has 2 coolers, not just the front. Call it a middle cooler.
It's finned (more surface area per sq. in. over smooth extrusion) and 2.5 times the size of the back cooler on the M-sled. AC left room to expand this cooler if it needs to be for some reason.
Racing Stations comments about modded HCR`s having cooling issues last spring, is the first I`ve heard (asked some questions myself back then). But, how you adjust your control box can be the difference. I like fuel and load in a 2-stroke. Might not have the most HP in the first 5 sec. but over the long run caries the most HP for the longest time.
I don`t have to pass an EPA test. EPA specs have added a lot of heat to the 2 stroke and in some cases have shortened the life of the the engine (won`t name no names LOL). I`ll find out this winter, but my math says I`ll be able to explore (volume of coolant) and rip (amount of coolant flow over a specific surface area) the same as my M-sleds.
Speaking of heat exchangers, where is the most cooling done on a sled. Many times on a cold fresh day where your on the throttle to just keep moving, when 35 mph forward momentum shows up as 50 mph on the speedo, the kind of day when you grab the running board as you step off the sled (oops started to daydream LOL, winters COMING) Anyhow on my sleds (on these kind of days when you are using fuel and making your sled do some work) the front heat exchanger is dripping water and the back one is packed with heavy snow, sometimes even frozen over. Any one else see that? I've often thought why do I need that one.
Lack of a front heat exchanger in the mountians is a backwards move IMHO. Lack of a rear heat exchanger may be the future. If your track throws the snow up to the rear heat exchanger does that snow not fall back onto the track and get carried forward to the front? Is the rear exchanger there to be air cooled on a trail ride?
Seems that way to me and I,ll find out this winter LOL.

Finally got a day on my HCR and was interested to see how the cooler deal worked out. I was on lots of hard pack and dropped the scratchers like i would have on any sled and had zero probs and we were doing a good speed for a fair while. The bonus was at the end of 120 miles there was no one flafe of snow or ice on my running brds ! The 1100 had tons on ice in the tunnel , i had zero. The Cfs and the 1100s both had a fair bit of ice in the running brds. Looks like the fact that the lack of rear cooler means the entire tunnel does not get heated and thus stays cold and no snow melts and turns to ice. I dont know how this will play out in the mtns with warmer temps and more somow but Im happy so far.

Hasnt been an issue in ak in 500 miles seen the light one time when i went 5 miles down a rode hauling *** 
i took my ice scratchers off too.
We have a ton of snow here though so that could be a big reason i only seen the light once.
I will tell you theres twice as much snow buildup on my buddies sno pros
Soon as i seen the light i jumped into he ditch for a sec and it went away instantly.

Interesting to see the 13 LE's getting the shorter coolers as some said they might.

OK - ready for a laugh? We "overheard" a guy at the Sneak Peak ask a A/C rep how not having a rear exchanger on the HCR would affect the Hy-Fax.
He was not sure how to respond.
Then at the Polaris booth the same guy asked their rep why the upward facing gauge was right there to look at - said the last thing he wanted to do was look at a gauge while riding.
I really hope this guy was joking in both instances and not just a tool.
