The 15/59 and 14/55 you mention are you using them ? Or just an example, if your racing them with which motor and class ?If your running a 15/59 or a 14/55 both are a 3.93 would one have a faster acceleration or would the weight of the gears be the only difference between the two choices. Just wondering if there are any advantages to different gear choices that equal close to the same ratio
What size track ? Dirt oval ? What RPMS are you getting with the 15 / 59 ?I’m on a 15/59 it’s in a kids class on box stock predator
Is he or she maximizing momentum ? Or on and off throttle to much ?I’m really not sure how big it is, maybe a 1/8th mile or alittle smaller. Dirt oval
If you measure "pitch diameter" and calculate the ratios, you will find that the larger gear set is a slightly lower gear ratio. This chart will show you how much.If your running a 15/59 or a 14/55 both are a 3.93 would one have a faster acceleration or would the weight of the gears be the only difference between the two choices.

herein is the problem .So I know 14/55 15/59 and 16/63 are basically the same final ratio so which one would pull out of the corner harder and still have the same top speed. The track has tighter corners and at 251 lb so they pull her out of the corners alittle but she’s a lot faster by the end of straightaway and still hasn’t mastered the art of passing
Until she figures out the art of passing that is hindering MOMENTUM your just chasing your tail with gearing, pick whichever one you feel helps her the most and stick with it as long as your hitting close your RPM target, work on her PREACH MOMENTUM, MOMENTUM, did I say MOMENTUM.So I know 14/55 15/59 and 16/63 are basically the same final ratio so which one would pull out of the corner harder and still have the same top speed.

If the adult classes can flatfoot it so can the rookie classes added weight has nothing to do with it, if sliding whole kart to much air pressure, not enough bite in tires, set up is off, or all of the above, if just rear is breaking out could be to much wheel input, if front sliding middle off if she entering to low to straight and to soon it will not exit right, if indeed it's wet soft yes you need an aggressive prep but don't do it in anticipation wait and see what you get.Ok thanks for the info I think I’m understanding it better. I’ve really been working with her on momentum. The only place I feel she is really losing any is easing off the gas in the corners. But she says if she stays in it more she can feel the tires start sliding. The only class that can really hold it wide open all the way around are stock and AKRA adult classes. I figured with her weight she would have a lot less available traction because a lot less weight on the tires. I’ve changed my prep this week to try and make up for that. Track has been pretty hard but keeps moisture in it all night. And with rain this week I figure the track will be soft and wet all night. I have a set of 33b’s that don’t have much life left I may just go ahead and use goat on them
