This is something that has always made me wonder. What are the actual physics involved to cause a converter's stall?

At least in our cars, the engine goes past the torque peak then settles down at a lower torque value for flash/stall. And keeping everything equal with gearing and weight, in good air it will flash at a higher rpm with increased torque.
