1/5 mile gearing?

[Racer6868]

Hello I am planning on going to Columbus speedway in Indiana. They claim it is a big 1/5 mile. I am a flat kart in the Super heavy and sumo class weighing at 420lbs and I run a clone engine. I am relatively new to karting. Any help would be greatly appreciated.

If Indeed it is little more than a 1/5 mile which is 1056 lf so say 1150 lf groove , a 15/61 should be pretty close and you'll lower rear as it grips up, that for regular gears , if mini a 12/50 ish would be close that also accounts for track not gripping up to well, can anyone who's raced there confirm how close I am.
