a 996 can do 0-60mph in 3 seconds. Lets presume it does it with linear acceleration.
60mph = 27m/s
acceleration during 0-60 run = 9 m/s/s
f=m x a
weight of 996 = 200kg
f = 200x9
f= 1800n
The 996 runs on 190/50/17 which have an overall diameter of around 26" or 0.66m
to provide 1800n of force 0.33m from the moment of rotation, the rear axle/sprocket has a torque value of 600n/m
