Given all else being equal and taking into account no other variable, will increasing the length/depth of the lugs or cleats on a tracked vehicle such as a snowmobile cause a definable change in the vehicles final drive ratio. For the purpose of this question final drive ratio is to be defined as the distance the vehicle moves with one full rotation of the drive system input and not accounting for any variation in the drivetrain such as CVT etc. 

 

I am open to suggestions but I think the above about covers it.

All other factors being constant, does lug height affect the FINAL DRIVE RATIO on a snowmobile, on a hypothetical, flat hard plane??? 

In other words, will a snowmobile travel further with one rotation of the track with 3" lugs, as compared to that same snowmobile with 1" lugs.  

THIS IS THE hypotheticaL situation!!! NOTHING ELSE!! 

No not CONVEYOR BELTS!! 

NO not 151" tracks!! 

NO, NOT ANYTHING ELSE , except whether or not a sled moves further with 3"  lugs, as compared to the EXACT SAME SLED with 1" lugs!! 

NO, no snow, no ice, no fukken rain, no hills, no slippage, no drive train flex, no NOTHING!!!! NO FUKKEN NOTHING!! 

The only thing in question is 3" VS 1" lugs!! That's all!! 

Replace "one rotation of the track" with "one rotation of the driveshaft", it's more accurate language.

We are stipulating to that. We agree that of course there is the crankshaft, primary clutch, belt, secondary clutch, jackshaft, gear set, driveshaft, drivers, and track as components of the drive train. We know that, but for purposes of this question, we are stipulating to their being CONSTANT. Therefore they should not be a part of the posed question.

Nope. One rotation of the driveshaft should be the constant that is the repeatable operation and the lug height is the variable. 

This is basic scientific method stuff. Constructing the experiment properly will give you the most accurate results.

How much will one turn of the driveshaft turn the track?

If you're putting $20k on the line, you should already know that.

It's not relevant, other than for a LESS ACCURATE reading. 

The more rotations of the track we make, the more ACCURATE the calculation is. 

If we could rotate those tracks 5-10 times, our reading would be most accurate. 

One rotation of the driveshaft will yield an almost imperceptable measurement. 

I have estimated that the difference in tracks is only 1.5 -2 % on a FULL track rotation. 

We are talking about tracks and lugs, that's what we'll measure. 

We have excluded all other components.

Then just rotate the driveshaft 1000 times.

If you try to do the test by rotating the track, it isn't a valid test, as the track doesn't rotate while on the sled. 

It's quite simple. Let's say the circumference on the driver is 12". 

1000 rotations should take the sled 1000', or 12,000". 

You need to measure the distance traveled in a 1" track vs a 3" track. At 1000 units of measurement, you should be able to see any difference to .1% resolution. This test should be repeated multiple times promote accuracy.

I'd rather strap you into a rack, and rotate your fukken head 10 times!!  

Take the bet, or SHUT THE FUCK UP!!!!!!!!!!!!!!!!!!!!!!

No way you'll pay. If you can't agree to such a very simple and controllable experiment, then you're not being an honest broker. 

If you rotate the track, it will in fact travel farther the taller the lug. But that's cheating. It doesn't rotate on the sled.

What does the track do then, if not rotate?

Nope. Tracks don't rotate on a sled. 

If it rotated it would just be a tire.

Just now, Polaris 550 said:

The track is driven around the suspension by the drive cogs.

Ok, what do you call the track turning one full revolution????? 

If a tire is flat it still rotates even though it’s not round

It is being driven. That's the proper verb describing what happens to the track. Not rotated, turned, etc.

The definition of rotation also includes a single central point. Hence the circle part...
