OK your our R & D man.
Thanks for volunteering, keep us update on the progress.
Volunteer? I own a machine shop I was thinking $$$
With the side panels so close... I was thinking drill and tap the cover to use bolts rather than studs/nuts... this way you could pop it off easily.
Cover might have to be machined to provide a flat surface to mount it to as well.
I put in a call to Freeagent to check on price, Part number and availabilty.
Will it fit with the side panels so close is the big question for me.
Only one way to find out.

$$$ why not?
Just make a product that works at a reasonable price.

Think one would fit on the 900?
So, (going one step further) could you take this pressurized area to pressurize the intake? Thus making a primary clutch driven supercharger, LOL

You guys crack me up.
Somebody has a new widget and within minutes you have convinced yourself you need one too. Not only that, you are now convinced they will work on all sleds and there is obviously a need for them.
What exactly do they do again? Do they sound like a Pete Jackson gear drive from a small block chevy?

I got word back.. no part numbers, price or availability yet.
It is a solid idea that when combined with a vent will help to cool the primary and belt.
I agree with Polzin on the "Duh factor".

I don't have a Pro (Really wish I did) but i think this is a really awsome idea and if it could be made to fit on the pro clutch I think other models could use it as well. Wouldn't it be the same concept for what polaris has on the flywheel? Looks like this would move some air around.
I have serous doubts it would fit on any IQ chassis RMK including the 900... just not enough room to the fender to fit IMO.
If you add positive pressure under the hood, does that keep air from coming in the vents?
If the high zoot ADS keeps alignment and center distance, is added cooling needed? Is Cat using a belt and suspenders due to previous mediocre drive system performance? How come the racer didn't have ADS in the three previous model years? Hmmm....
Could the clutch sheaves use more (any) cooling? For sure. Not quite sold on a teeny centrifugal fan yet. Clever idea though. One thing it will do and that is spread belt dust to previously clean corners underhood, mebbe even on yer new Klim's.....
A little trimming with a Leatherman and it should fit.

i was kind of thinking a one piece billet cover/fan might be the way to go for attachment ,balance purposes . Imaigine what indydan will have to say about that configuration. I also think incorporating it into a 1 piece cover would allow fitment on more sleds. I would worrry what happens to plastic fans when they hit the side panel a 8k too! CRUNCH!
just thinking more about it. im convinced the idea has real merit but needs serious refinment IMO . one of my first thoughts is ...How many fans run higer than an idle on most sleds. at triple those speeds its a whole new ballgame. where the dynamic forces,hp useage ,etc are concerned

That piece of plastic will save the side panel the first time you lay the sled over. As long as it's tougher than the side panel it will be fine. Even if there is some damage it will be alot less than without this piece. Takes about 0.1 seconds for a clutch to router a hole in the side panel. The "cooling" aspect was an after thought
it could but the proximity to the side panel and cold air intake is the best advantge of the set up with out ducting it would just recirculate the warm air.

you may recall that the entire engine was once cooled in a similar way.And if no one tried anything new we would still be riding 340 fanners.
instead we ride 200hp 450# turbo charged monsters. YOUR WELCOME !
Someone throw a link to STM and Thunderproducts!!
Not a whole lot of re-design for what they already sell.
1 cover would then give you:
- large cover bearing
- lesss flex/distortion
- adjustable belt side-crearence
- AND cooling!
I'd buy that for a dollar....

I would worry about a couple of things with this concept. First more rotating mass on the movable sheave. I'm not sure the crank bearing need any more resistance. Second, I would assume there is some weight to any approach and that would need to be taken into account on fly weights for shift points.
Interesting discussion though.
