The next big innovation in snowmobiling?
- Thread starter Clarke673
- Start date
a better drive system that doesnt loose so much of the power, imagine not loosing dang near half the power dragging all those parts in a circle, and the whole belt heat issues.
as for motors, DI 2 stroke is gonna help a ton, they make good power, but with the way of the environazis i beleive the move to 4 strokes is kinda inevatable on sleds, but at least we have DI, that will save us a while.
i think after this winter and the DOO 600 E-TEC will show us how thats going to end up working.

Yes, as many of you have said, drive train advancements. We are really seeing the limitations of the current designs of the CVT. Especially, in the big bore high torque sleds that most of us ride.
Extremely inefficient. Somewhere around 40% power loss through the clutches. My memory may be going, correct me if I'm wrong. This is causing excessive heat, belt issues, etc.
So hypothetically, a 150hp sled is putting down around 90hp to the track. If we could increase efficiency. Manufactures could then build bulletproof 140hp sleds that can put 125hp to the track. How much fun would that be.

I think this is a great idea and would open up a lot more possibilities.
Unfornutaley, 4 strokes will be the norm before too long. The emissions being the major reasons. However, they are heavier and more expensive to rebuild/maintane.
I did see in a Popular Science magazine a few years ago, someone was developing a bladder to seperate the crankcase oil from the intake charge on a 2 stroke. Did wonders to clean up the emissions, they just didn't have a material that would last long enough in that kind of environment. Someone should spend time focusing on that technology and we may be able to keep our beloved 2 strokes around a little longer!

Now that's funny!
I am afraid that Barrack is going to cause 2 of the OEMs to go under.

Somewhere between too dumb to quit and flat earth
Why can't you just run your secondary off of the drivers? Then just have your brake rotor on the other side? This design to me seems like a GREAT idea if you can get the clutching Wright?
As far as the E-tec
Its great, 15% more efficient, but it also gains 15 pounds, and keeps the same power. That’s great, but the changes they made to it really aren’t amazing.

Because the secondary would hang down past the belly pan, and you still need gear reduction. Its been tried before.
just not enough gear reduction..you would need a secodary clutch twice as big as the current one....how would you keep it out of the way?

Less is more.
One ski that is.

E-tec, Efi, and four cycle power?
The best part, we have it now!

Sure, Honda made a 2-stroke diesel for the Paris-Dakar race a few years back. Can't remember how it did though.

Played around with that idea from '98 to '01. It works as well as it hurts you. Funny how you find out how a sleds track can cavitate in different snow conditions.

Personally I agree with most people as somebody needs to find a way to put more of the power to the ground and not get lost on the way there...
But there's so many directions that technology could go.
Someone also mentioned the new possibilities in plastics and polymers. The technology is already there but I wonder if it's cost effective. For instance, imagine a front bulkhead made out of a plastic that could flex and absorb a hit from a stump, rock etc and cut down on breakage. Sure things will always break but it could cut down on some of the those hard hits. There's also metals out there that after major distortion can be heated and come back to their original shape. Again, cost effective???
In response to Boyesons exhaust valve breakthrough.... I've been wondering why this hasn't been done long before this. The old 670 got me thinking about it. Why not have a two stroke engine with a system of intake and exhaust valves? This would not only make an engine more fuel efficient and cut emissions but the power output would be unbelievable. So much back pressure is lost as well as burnt fuel being trapped in the cylinders on the next ignition. This could cut down on detonation problems and exhaust scavenging would be a lot better. It would also boost torque values. Remember what the bottom end torque was like on the 670s?
It's exciting to think of what could happen next.

Heres could be the next drive system, the Aprillia 850 Mana automatic CVT

There is so much to be gained with the use of more advanced materials. Were gonna see carbon fiber, titanium and different plastic allover the place.
Carbon Nanotubes.
2moto on a R1 motorcycle with turbo?
What's the efficiency on a motorcycle transmission, why not just adapt one of those to a snowmobile, and shift? Seems to work on the 2motos.

diesel with the new tech may work. diesel is as easy to start as a gas now.
my neighbor has a apex and his diesel ford will start before the apex when its cold.
i could see something to get more power down to the track like others have said.
