Explination for Straight Cuts Please

Hey all, I did a quick search both site and internet and I did not find what I am looking for. I am looking for a difference in what the different gear ratio's provide.

 

If you were running 300' dirt which ratio would you want, depending on motor size, lets say 421 running on meth for arguments sake. 2.86 is standard gear ratio correct? Would dropping to 2.68 give faster times? Also how much more power would be required for 2.68, and 2.28?

 

Maybe if someone could give opinions on all gear options, I would greatly appreciate it.

 

Thanks,

 

Adam

biggest difference i think is so you dont have to run a big ass sprocket on the engine. useful for the asphalt guys. otherwise i would think stock ratio would be fine for a 421?

You would spin your clutch faster making lock up arm react faster, also would trans shafts spinning faster aid override slider life?

My thought was like changing pinion shaft gears in a car rearend. Where 411 are a lower gearing making more torque but 383 will get more speed. Since an atv also has chain and sprockets I could change gearing there aswell but allowing a larger range of gear changing in the long run.
