Theoretically, the power loss in a drive-line is 15 to 18% for a modern car. Lets say our old school technology Model "A" has a drive-line power consumption of 20%. Then the power at the rear wheels would be 32 HP. The same analogy applies to the engine's torque rating which is 128 Lbs-Ft @1000 RPM at the flywheel. So with a 20% drive-line consumption, that leaves 102.4 Lbs-Ft of torque at the rear wheels.
Is there a dynamometer test result for a stock Model "A" with a fresh engine and restored drive-line?
