Best vent kit/system

Guys,

The 17's don't have much venting stock, so what is the best vent system to dump heat from the clutch side?

Anyone used or installed a blow hole on an Axys? Looks like it sits in front of the clutch, is that a hassel to remove when pulling the belt? Does it connect to a factory harness for power?

What is the best system, passive vents or powered blow hole?

Thanks Guys
 
Blow hole

I did the mtntk blowhole, very easy to install, it sits between the clutches, uses the bolt hole where the oil reservoir mounts to the clutch shield, and yes plugs right into the factory harness. Haven't ridden my new axys with it yet, but have the ridden the 14 and 15 pros with them on them. IMO the blowhole is the best vent/clutch heat removers ever. They really evacuate the heat from your clutches well!

At SLP in our testing, we found that by adding our vents to the PTO (clutch) side panels of an Axys, we increased wind speeds coming out of the foot well area up to 13MPH. The reason we gained so much there is because the clutches are a pretty efficient fan. By providing area for cold air inlet through the side panel, we are able to cool the clutches down very effectively through bringing cold air through the panel, across the clutches and out the footwell vent. The part number for the clutch side vent kit is 32-634 and price is $119.95.


Another item that you should consider is our torque arm. The torque arm keeps the engine in place under hard acceleration rather than allowing it to flex in its motor mounts toward the driven clutch. This also helps eliminate belt heat as it keeps clutch alignment and center to center within spec even during the hardest pulls. We have seen a performance increase of 1 1/2 to 2 lengths in acceleration by just bolting on a torque arm. The torque arm part number is 23-69 for models without electric start or 23-70 for electric start models. Pricing is $109.95.


Let us know if you have any questions.

What happens when that "cold air inlet through the side panel" is covered with snow? Air doesn't flow at all.

So, on deep powder days, when one needs ventilation the most, i would think a "forced air" venting system would work best, and be the best ventilation system for ALL situations rather than just on those low snow days where the vents aren't covered with snow.

So far, the blow hole venting concept is superior. I am hoping you all will come up with something similar . . .soon? :)

The vents are in a vertical position. Yes, when you sidehill aggressively to that side, the vents will be covered with snow, but as soon as the sled pops out of the snow, the vents shed the snow (the material we use and the way we bevel it aids in the shedding process). Also, snow is very porous and unless the vents ice over (and that condition is extremely rare), they will always be flowing a certain amount of air. The clutches act as the air pump and do this quite efficiently.


It has been my experience that venting the side panel has been a very effective way to manage heat. Even on the deepest snow days, I have not seen an issue related to heat oversaturation with ventilated side panels.

I'm thinking about the blowhole but with that being said, SLP vent kits are a tried and true method to decreasing clutch heat. Vents get snow on them all the time and still do a decent job at aiding in cooling down the clutch and engine. Splitting hairs to think of all the "what if" situations out there. The skinny of it is, vents work well too.
 
Really enjoyed the Blow hole on my 14-15 Pro- worked great-
With the way the Axys blow hole is mounted in a few client's sleds it dosen't seem to be as effective of drawing the hot air out as in years prior- IMHO
( 90* angle vs. straight shot )- but anything is better than nothing.
I like the chimney vent from F-N-I and the vent infront of the primary from 2 -cool
Tough material and never had any issues with their products over the years.
 
look just my take but the blowhole and vents go hand and hand. if your stock vents are getting clogged, where are you going to get the air from to blow out? will a blowhole work good yea. will vents work good yea. will they work GREAT together IMO indefinitely!!! {just food for the mind} put that blowhole in a box and turn it on. it wont push a large volume until it gets adequate venting, so start cutting holes in the box and covering them with vent mesh {what ever mesh u like to use on your vents}until u reach an adequate flow and know u will need that on both sides of the sled in addition to stock vents to account for plugging or sidehilling ... in the end we can never have "to much air flow" and in my mind it starts with proper vents to let the cold air enter and ends with the evacuation of the hot air out "IE" {THE BLOWHOLE} well just my 0.02
 
Guys, great job covering the subject. Great discussion of the options that work and what to be concerned about!

I very much appreciate your experience and insight. The 16/17's have virtually no ventilation stock so I will have to cut some into the panels.

Thanks as always!
