Some of what you say makes sense, but the rationale is not true (sorry)
Torque is not work, it is force only. When a torque wrench is applied to a head bolt and 85 ftlbs of torque is applied, at the last instant when the bolt stops turning, no work is being done, no Horse Power is generated.
HP is the same category of measurment as Watts (KW actually) and a accurately rated one hundred HP device turning at its rated high RPM (lets say 4000rpm)will produce the same plowing ability ground speed depth etc, as a 100HP accurately rated device that turns 1000rpm.
Torque=force only.
HP=force X distance X time
