You guys who drag race 1/8 mile, do you set up your gears so your sled reaches it's max speed at the finish line? or gear taller so if you kept going you would still go faster?? I know taller gearing works if you have a light sled with lots of HP but say it's for a normal heavy sled and a heavy driver, (like me)..What would ideal gearing be?

You usually gear down for the 1/8 mile (660'). How much traction do you have now? As you gear down traction becomes more of an issue.

Hey, I have lots of traction a 144x 2.0" camoplast finger type track, it hooks up awesome, much better then the stock track did last year. Here is a pic>

Nice track! What surface do you run on in the 660'?

drag racing
The pictures really help in your post. Is everyone on the same page you are racing against. Lets not forget it is a mountain max and you have done alot of nice mods but they add lots of weight. The track,hitch and gas rack,extra coolers it all adds up and I would think this would hold you back. Also you have done some major mods and the season is just starting so there is no doubt in my mind you have some bugs to work out. You have a really nice job done on your machine and I am doing most of the mods you are doing over time and it makes me wonder what things I will run into. These mods will work very nice in the mountains as horsepower is a great asset. It is hard to get a machine that will both drag race and climb mountains.

The surface im racing on is a groomed track with a trail groomer, so it's pretty hard packed.
I know I don't have a race sled here, but I love to make the trips to go racing, I use my sled for losts of things, trail riding, deep snow at times, ditch banging, I know the other things add more weight and im already a hefty 250 ibs so I dont' extpect to win all the time, but i want my sled to do the best it can geared for 1/8 mile is fast enough for all my other driving too, where I and the sled are both heavy I figured lower gearing would work ok, with 23/39 i ran 100mph on the speedo so i changed it down to 22/39 (still 8 tooth drivers) and she topped out at about 95mph but it took more then 1/8 mile to get there...........
Finally as for my competition, it's all kinds from RMK's to F7's I know I have lots of 'fine tuning' to do, since i made so many changes since last year, the gearing is one, then the helix angle is second, and I still have some fine tuning to do on my clutch yet, it's overrevving slightly, got heavier weight to go in the tips .
Below is a pic after I modified my track, cut down from 2.25 to about 2.0" and I cut out the center paddles over the track windows to clear my coolers, lots of time there.........hehe.
