2019 new vents and clutching

Are these stock or an accessory? Any word on the calibration?

Vents are stock on gen 4 narrow body. I don't believe the new clutch parts have been released.

And that is an intake vent, draws through the secondary and out the footwell.
I forgot how much foam these things have from the factory. Sheesh.
Very nice to see that they are taking the belt issue seriously. My only concern would be if the plastics deform much when laying the machine on its side and if things got chewed up much from the clutches. I know, I know, rubber side down but that doesn't always happen.:face-icon-small-blu
I expect that BRP will have these sleds dialed this season.

I say the updates for people with 17 and 18 sleds should get the new vent and side panel port. Looks like it should work great

Better Belt Cooling for All Sleds
That's a good question! I won't pretend to have the answer, but I know it wasn't much of a problem for the REV and RT having the same concept for the air intake. The thing with the air intake is that it was critical for the engine which made it a poor design. But for air intake of the clutches that doesn't need extraordinary filtration, I think it is brilliant!
I don't believe and I certainly hope they didn't have this patented, because I firmly believe/hope to eventually see this standard on all sleds. In my opinion there is no good reason to have any hot belts on any sled of any manufacture. The idea that we need to remove all foam or cut panels to getting belt cooling just doesn't make sense to me, at least no in 2018.

Its ok if they patent This special ventilation as it is not required on all sleds.
Finally, cat has figured out how to properly clutch a sled.
I hear good belt life from 16-17s and i know 18s will easily get 1,000miles of hard mountain riding.

yep, their solution was let somebody else handle the clutches. good move. like when polaris quit making their own handle bars or whatever you call those things they used to give us.
nice additional bandaid there :face-icon-small-win
We'll see. The new panel and secondary cover is a nice piece for some enterprising tinker'er to mount an electric fan to pull air up and out of the panel, too. BRP comes up with their share of new ideas, some of them actually work, maybe this will be another.
On a different track, I don't think it's a coincidence that AC figured out they needed clutching help after working side-by-side with Y, and learning more about how not to blow belts on high hp, high torque motors.

Wonder if BRP will claim another 70f drop in clutch temps.

With the design of the cover and clutch sheave fins the air is flowed out the foot well and drawn in the vent. So maybe force more air in through the vent and keep the foot well clear of snow, if that is possible

The air intake is by far the best I have ever seen and hopefully the best thing we have seen with sleds since the ETEC. But I don't understand the exit strategy. Check the Ski-Doo U: Tips for Technical Mountain Riding. The left footwell is completely blocked. I'm guessing that we need a beginning to eventually see the end.

Like I said. Hard to keep the foot well clear of snow
If the 'vent ' doesn't create enough heat or enough air movement, u will end up with a giant ice formation there......

I'd bet it ice anyway to some degree unless you can heat the channel and have a drain port on the bottom.
IMHO a little venting experience with a 05-06 era 866cc engine.
Im gonna add velour vents on the top and a regular screen type across the side/bottom.
Gonna do similar on the exhaust side.
Plus drilled holes on the plastic belt cover.
Too bad we cant float the secondary BUT I read on here someone cut the channel on the shaft for secondary float?
