Here is what a differential is supposed to do: Always distribute equal amounts of torque to both wheels - always react to resistance (traction) to allow a wheel with more resistance to rotate less and a wheel with less resistance rotate more (needed in turns where the inside has to rotate less than the outside wheel). The rpm difference created by the diffrential is always proportional. If the inside tire rotates 15 rpm less in a turn than going straight - then the outside tire will rotate 15 rpm more than going straight.
