Lyndon,

Any thoughts on how the higher ratio would affect the Snow Master with the narrower tracks? Even though they are narrower than stock, do you think this would still be too much track to run a higher ratio when considering the herringbone grousers?

My house sits at 10,200 feet and I'd be driving to elevations in the neighborhood of 13K. This high up it seems somewhat doubtful that I'd be able to get the Snow Master up to 13+ miles an hour in its "stock" configuration with the narrower tracks. I'm not necessarily looking for it to do ST4 speeds, but if I could get it into the neighborhood of 16-18 mph that would be nice.

your top speed on the st-4 will be limited to max engine rpm the snow master with cut tracks should be able to hit its top speed going up hill on a groomed trail at your altitude i think you will find the lower gear set to be your friend if you want to run in high gear

Just took my st4 #58025 on a 12 mile round trip up to 12,000 ft above sea level. No issues, but I am already thinking about a 1776cc with fuel injection. We spent a lot of the time in 2nd gear at about 8 mph climbing on packed trails. I would like to spend a little more time in 3rd even when climbing. Definitely feel the lack of hp at this kind of altitude mainly when going up hill or in untracked snow.

good info mine has plenty of power at sea level i find the only limitation now is that with my pressure plate being weak i have to down shift to 3rd on hills because the engine will overcome the clutch and slip can't wait in another 2 weeks all my stuff should be here to redo the lower end and get rid of the excessive end play and have a new 200mm clutch

Might also be worth noting that there should only be half the herringbone grousers on this machine as a typical Snow Master, which may help out in terms of not eating up as much horsepower.

Edit: Just realized this probably isn't the case. I found this pic of a Snow Master on Wikipedia, which makes it seem as though only the inner/outer belting may have been removed and what remains is the middle two? Outer belts seem like they were only joined at every 3rd or 4th grouser.

LOL. Thats my Snow Master. She has the 11 tooth small gear set and I believe the larger 38 tooth big sprockets. This picture was taken just outside of Elko in Lamoyle Canyon NV. The wikepedia has the location wrong. Anyway I was able to run her at about 13 to 14 mph just below red line. I now have a set of the 15 tooth small gear sets. When I put her back together I will have those installed along with a 120 hp motor. Im at about 8,000 at my back door and I only go up from there. Alos. Those tracks a very heavy compared to a set of Snow Tracs! You would easily have an additional 400 pounds diffrence in them alone! If you dont believe me come on over and help me roll them around. Bring your ST4 tracs and lets see. lol. Your back will thank you once your start pushing the much light Snow Trac tracks around!

Lyndon, So, both the Master and Trac have VW bus transaxels, and is the only difference in their sprocket combination? I was wondering, because I've talked to owners who have narrowed their wide tracks, but in 4th gear they don't feel they would have the power (1600) to go any faster, even if they changed their sprocket gearing. I'm just trying to figure out how you get more speed out of a Master. (is the answer: sell the Master and buy the Trac?) Thanks. Wheels

I flew out to Eugene to look at this one, just got back last night, took two days. My wife says I should look at some others before I buy any thing. So if anyone has a Trac or a Master that I could look at, good shape or bad, I would sure appreciate the opportunity to see and learn more.
Also, I took a little video with my phone, didn't turn out real good-I think I've dropped it too many times - but you can get some idea. If anyone else is interested, I'd be glad to share what I've got. Wheels
