Troy I have hit 185 a time or two going too slow on hard pack ( I didn't have my scratchers down). The light didn't come on and it didn't go into the limp mode. I agree with you that in the spring on warmer days with crud snow even with the scratchers down, we may see some high temps. This is why I'm looking into the flap issue now, I don't want problems later. I'm also curious as to the temp limit.
Stone:
If you get near 190, you might want to shut her down. Happened to me a couple times last Spring messing around in the trees and also when getting up on the ridgetops when you can't haul *** and kick up any snow. Don't know at what temp it goes into limp mode. And yes, that's with the scratchers down. Early morning take offs in the Spring are a PITA until the snow softens up, then all is well. Just have to keep an eye on the temp gauge.

Went out ridding in West Yellowstone on thanksgiving.... First of al it was FUN... nice Weather!!!... But we had 1 2011 Pro Rmk 155 and 2 2011 RMK Assaults.. Between the heat ratios on these... hardpack with the scratchers down the 2011 Pro got up to 160.. The 2011 RMK assaults were at 135-140 Both verry consistant on the hardpack snow... Now im just brain storming but i think the assault track throws up more snow on the hardpack compared to the pro rmk powder track... Now we also had a 2012 Pro Rmk and a 2012 Assault... ON and OFF the hardpacked trails they both stayed at a consistant 125 degrees....With the scrachers down.... we ride with the scrachers down all the time.... but i think the 12 models have a little better cooling system on them... I also noticed a little more power and some more snappyness... Just my 0.02! Cheers!!!
Installed the PDP snowflap on mine and now I dont have to use scratchers where I had to last year. Still have to watch the temps though, but with scratchers down, I have never had a problem.
Is there a temp light? At what temp does it come on. Has anyone installed a aftermarket heat exchanger?
Proper running temp?
What is the PRoper runnning temp on the pro? first ride of the season 2 weeks ago now in minmal snow in saskatchewan, the highest i hit was about 130 deg lowest being 120 ish?
Anyone know?
Sled is a 12' 800 Pro is that makes any difference compared to 11

I wonder if by deleting the cooler on the Pro, Polaris was trying to free up space and gain some track speed?
Simply weight. Same reason they reduced the size of the tunnel coolers. They were trying to meet a benchmark for the sled, and it worked. If ridden in good snow, or higher speed with scratchers, not an issue. It's when the conditions get sketchy, dry fluff, can't get enough speed that temps go up, quickly. JMPE.
I live in Jellystone. My 11 is tough to get below 150 in good snow, like we had all last yr. I had the engine "slow" due to heat before I kept the guage on. Just got it back from the dealer and he said the temps are normal?

My 12 PRO 800 runs 127 to 131 in good snow at normal speeds. On hard pack (like last weekend) with the scratchers down and duck tape over my flap holes, I ran around 135, at normal speeds. If you slow down on hard snow the temp will quickly get to 150 or higher if you stay slow.

Good snow flap test today. My buddy's '12 163 Pro with the ported flap and scratchers down was running up to 173* on the groomed trail into Allen Creek. My '12 163 Pro has an IQ snow flap. Same trail with scratchers down, my sled never went above 127*. When we got to the cabin, there was almost no snow in his tunnel, while mine had a 2" layer of slush inside the tunnel.
Sent from my iPhone when I should be sledding.

That's pretty amazing.
I take it you guys were riding together (same day, time of day, etc,) when this happened?

yeah, same thing I found out...if ya ride questionable snow a lot just do 2 things, put a iq flap on it and run the extra bogie wheels (just for hyfax wear)
