I bet around 1500 where peak torque is... you may get a run at the hill with the horsepower but when it settles in its the torque doing the work.
Yes 1500 is where peak torque is. Yet if I can't pull a hill at say 60 mph at 1500, I split a gear to 1700 and suddenly I'm pulling it at 60 mph? Engine torque is lower, HP is higher, and I'm making more torque to the wheels.

Also the torque wrench analogy makes me . How much torque can you make on one personally? So what if you were in the engine bay of a car with your torque wrench, would the car go anywhere? It would barely move. You can make a decent amount of torque but it's at such a low RPM it is quite useless for doing any actual work. The human body can produce a lot of torque, but maybe 1/5 a HP.

Your statement here if I were your shop foreman I would make you turn your keys in and encourage a career path change.

Hey guess what amigo..... the human body can't produce horsepower or torque in the terms that we're discussing.

The phucking definition of torque we're discussing is how strong a rotation is that takes place and horsepower is the speed of the rotation ... not how many fleshlight or shakeweight beats you can do per second Allan.
