OK wow, a differential doesn't change horsepower or torque, its alters the rpm vs gear and speed. for instance my e30 with it's 4.10 diffis at 3000 rpm at 80 in 5th gear, with a 2.93 diff my car will sit at lower rpm's. the way the power is felt is changed obviously and acceleration can be improved but horsepower/ torque is not changed.
