I am looking for more top end mph, right now I’m hitting 90mph on hard pack, I run a lot of RR grade trails and would like to see 105-110. Specs say 22/48 stock, thinking of changing bottom to 41 or 38. I’m 210lbs with 102 picks.

105-110 with a 146/1.6 and picks???

RXC 6000 1.35" 23/40(slipper)
RR 8000 1.25" 21/41
SnoPro 8000 1.0" 21/38

maybe the 41 lower gear would get you to the lower end of your goal without ruining the bottom end performance?

this is fun to plug data in

I entered my info and ended up adjusting the clutch ratio to .96. The .90 ratio listed does not add up to real world findings. This made all the numbers jive with 22/48 and 8150 rpm to be about 95 mph as this is what i see in the real world. That being said 21/41 "should be" about 106...1.6 riot with 136 studs...id like more top end but dont want to sacrifice any bottom...

Gearing it to the 21/41 with that much track will only shift to the 1;1 if that, 106-110 is a hole new ball game in these chassies unless slammed to ground. you need at least 175hp to attain it.

23/47 be in line with the 20/41 I've ran on 141" XF's, I called it 105, should be good for you but anything over 105 is going to be a battle period, in real mph

Im running 21/41 with a studded 137 storm 150 and 100 is seeming to be impossible to get. I had 95 last year and low 90s this season.

Going to try some clutching changes today and see if i can get closer to 100.
