Max revs depends on many factors:
engine,jetting,circuit, chassis setup
For instance we get higher revs at PFI than we do up the dragon straight at GYG(uphill) The power band in minimax drops off past 11.5K and the kart will stop accelerating and reaches 'terminal velocity' where by road resistance equals engine power. simple things such as a small difference in rear tyre circumferences will affect top speed-easy to always blame the engine and carb setup. If you are using data logging you want to gear up to reach max revs at the end of the staight not half way down it. Some engines have lots of bottom end power others are high revving screamers- if the driver can maintain speed through the corners(cadets are good at this)you want the smallest gear ratio you can get away with- without getting outdragged- only the stop watch will tell you what is best - you might find that max revs of say 11.3K is that fastest solution - Test and log your findings.

Theres a great bit of software called kartdata 2000 which I always find useful.
