We won a LOT of races (and several championships) running a 15 driver at this fellow's track (jr1 champ with purple plate flathead.)
There's more to gearing than track size alone.
Restrictor plate racing is all about momentum and being real smooth behind the wheel. I was fortunate to have two fairly smooth drivers over the years so we could free our karts up and let'em roll.
It's all a matter of corner rpm drop and power band of your engine.
Gear for your engine, the track, and your driver. It all has to work together.
14:63 will get you in the ballpark.
15:64 will walk the dog on them if you have your ducks in a row.
