so i am planning to build a go kart(adsbygoogle = window.adsbygoogle || []).push({});

i have purchased the engine with following specs:

power =8.2 KW (11.1 Ps) @8000 rpm

torque= 11N-m @5000 rpm

Calculations:

rolling force=221 N

drag force=26 N

total tractive force=221+26=247N

torque at wheel= 247 X 0.1 ( 20 cm wheels)

= 24.7

then i calculated power =Ft X vmax

=247 X 23/1000 =5.68 KW (23m/s is limit at my track)

the i calculated wheel rpm=2100 by power rpm torque relation

found out the gear ratio =engine rpm/wheel rpm

=3.7

14X3.7=axle teeth

52=axle teeth i am at planning stage i wanna know if iam right uptill now or wrong

all so wanna know how to calculate pitch of teeth if i want to cast the sprocket
