I wish my engine was powerful enough to give me that torque roll effect on take off, i sit longingly waiting with my foot hovering over the right rudder but alas my old lycoming just keeps the aircraft pointing straight ahead down the strip.
Piperboy, you are getting a torque roll effect, which is offset by the rotating airflow effect. With a weedy Lycoming there (should be) a slight yaw to the left on take off (or in any high power / low speed scenario). More yet on a soft field take off, as the torque-induced roll will put more pressure on the left main wheel which will drag in the mud a bit more than the right one.

Indeed, this torque-roll was the only way I could get the Yak52 to steer at a slippery, muddy, winter Barton. Differential brake had no effect whatever, but whacking power on and off sharply would make it turn left or right quite effectively as the appropriate wheel dug in.
