The bit about 2 strokes having less torque is not true for the dedicated 2 stroke pattern engines from Webra and OS. There are different setups but the more common 2 stroke configurations turn a 17x12 APC at 7800-8200. The only 4 stroke that can do this is the YS DZ, though most DZ users generally prefer to run lower diameter at a higher rpm.

One wouldn't really want to run any of the above engines in older pattern designs. There are practical limits to the old saying, "You can't have too much horsepower".
