Ferrari Mailing List: Re: Torque vs. HP explained in 90 seconds

[Rick Moseley (ramosel]

Great presentation on how an electric motor delivers maximum torque at 0 (zero) RPM.  

  I had the privilege of working a few weeks in Ed Pink's shop one summer during High School (a favor to my older brother).  One Friday evening a few legendary drag racers showed up.  So I asked them to explain the relation between HP and Torque.   Mert Littlefield gave me the best and shortest answer I've ever heard.   

Torque provides acceleration, Horsepower sustains torque.  

I have a few friends today who are on the top rung of race motor engineering and when I repeat Mert's quote... They scratch their heads, think about it a bit and reluctantly say "yup".  They all say there is more to it... but it takes a lot more words to say the same thing in engineering speak.  Just about everyone has written it down... The one who didn't I know has a photographic memory.
