i use the 36 60 2000 motor in my buggy on 4s and it has the 43/13 diffs. i am racing it on a smaller indoor track and using a 14/44 setup. it has really good power and runs cool at 110 after a 5 minute run but the indoor temp is only around 55 to 60f.
running it outdoors on larger tracks i will try a 15 tooth if it dosent get too hot. honestly it has great racing acceleration and speed with the 14 tooth.
i would think a 17 tooth will get you into trouble. also those gearing charts are misleading at times. when i had my novak 6.5 system in my car i clocked it at 37 with my radar gun. i havent clocked it with the medusa and 14 tooth but i can tell you it is faster i would say 40 or a shade faster.
always gear your car so it runs at a pace you can handle but most importantly dosent get the system hot.
