I imagine the zero rpm refers to the output/power turbine, not the compressor turbine. Torque is the twisting force - you don't have to be moving to have torque. Just ask anyone stuggling with a rusted bolt. :) Ken Quoting "Swygert, Francis G MSgt 436 CES/CECM" <Francis.Swygert3@xxxxxxxxxxxx>: > I looked at the site.
