I did the calculation, using what I thought to be conservative numbers:
I assumed the Center of Mass was at the Center of Geometry of the wheels
I assumed the trackwidth/wheelbase ratio was 1/2 (it appears to be a bit better than that from the picture.
I assumed the coefficient of friction of the wheels he's using is 1.2
I assumed the wheels are 6".
I assumed a total weight of 150lbs.
I assumed 10% loss of torque in the gearbox and sprockets.
Using Billbo911's 11.7:1 gear ratio, I calculated ~180 oz-in torque required at each motor.
