What kinda track speeds are your 166's holding?

[94fordguy]

Just like the title says... I've been curious about this for a while as what track speed a sled can hold tells a lot about it IMO....

What kinda speeds are you guys pulling on long climbs?

2 weeks ago, 2 ft light, powder snow - 45 mph track speed consistently on several runs

last week, heavy snow, about 1 ft deep - 40-41 mph track speed consistently on several runs


800 miles on my clutching and belt running the 166 track, bone stock motor with an SLP can... 7500 RPM, 18:39 gearing



My buddy runnin an 06 166 same climb last weekend - 43 mph consistently, SLP pipe/can/y-pipe and reflash... about 400 miles on his clutching and belt, 18:42 gearing




I know A LOT of factors affect track speed, but I'm still curious.

Thanks

You must be running one of thoes little 900s, gear down your track speed should come up Im running around 60mph in average conditions soft stuff around65+ with a 151 and a little more motor.19x42 gears.

What's your definition of a little more motor, a 1000?

50 to 55 mph with the 166 at 8 to 10000ft is what mine usually pulls, I don't know about this 70 mph stuff, must be lower elevation

65 - 70mph??? do 300+hp turbo yammi's even pull that?

less weight and strong motor @ 214hp 7500- 9000ft

that would do it... shorter track, less rotating mass and traction, and 64 more horsepower... you better be pulling 70 mph. lol

my buddies M1000 153 pulls 55-60 mph depending on snow... but again your talking about a sled with considerably more horsepower & torque on a shorter track.
