The 1-1 pattern is better in deep snow but the 2-1 seems to do better when it's a little more setup.

I haven't seen a G4 sled. I put 8 tooth drivers on my T3, better approach angle etc. There will probably be room for a 7 tooth in the 3.5" pitch. We'll have to see what the sled has for extra room.
I think you need to check your math. Even with rounding to one decimal point it's only 0.9" of diametrical difference. Which is less than half inch of radial clearance needed.
Just bored, so I checked your math. Regardless of brand or track pitch, I won't run 6 or 7 tooth drivers.
I checked his math. He is correct. 6 tooth is 6.68" diameter. 7 tooth is 7.80" diameter.
Sorry to burst ur bubbles.
Those measurements are guesses and i doubt they are accurate.

So ur "guess" is that Skidoo will follow ur rules and not "fudge".
I am sure ur numbers are close but i doubt they are exact which makes them incorrect, correct?

So the G4 is down to a 6 tooth driver and only 3 can be driving at any time, how low can you go without ratcheting or overloading the actual drive contact surfaces?
The Conquer 2.8 may be a great track but with the increased torque of the 850 and a 6 tooth driver, you may see windows get ripped out. This might happen to the doo track too, especially when turbos come into play.
Also the less drive surfaces, I expect the rougher the feel with more vibration??
Has anyone thought about this or does anyone even care?:face-icon-small-blu
For clarification;
Earlier when i commented on guessing and measurements, i was referring to driver dimensions only!
6tooth -7tooth.
Here are a few facts:
1. Cat has an 8tooth driver and a 7tooth driver for the proclimb.
2. 7 is 87.5% of 8, that is a 12.5% reduction.
3. The diameter of the 7tooth driver is less than 9% smaller than the 8tooth.
4. Both drivers fit the same 3in pitch track, even though drivers pitch ranges from ~2.86"- ~3".
So, now that u all have that knowledge you, should understand that the exact diameter of a 3.5" pitch 7tooth driver will not be known till one is made.

8 x 2.86 = 22.88"
7 x 3 = 21"
6 x 3.5 = 21"
7 x 3.5 = 24.5 (very big)...
I did the 8/2.86 XM drivers in a T3 (regeared accordingly) and a 3" track and worked well, unfortunately the the new 3.5" track wont allow a diff driver (7) or pitch since its waaay diff...
The 162/3" track which will fit with a 8/2.86 driver BUT the rails will be too long for the bigger driver/shorter track...
I am tempted to go 162/2.8/3 pitch, 8/2.86 drivers, switch rails to ice age (better rail curve than stock) and will see at least a 5-6 deg BETTER AOA from this combo but hate to loose 3" of track length...
Pretty deep thoughts for a "parts changer"...LOL-BJ
