RE: Tq vs. hp
hp= torque x rpm / 5252
torque is defined as a force around a given point, applied at a radius from that point.
power is how much work can be done in an amount of time, so luckythirteen13 is right.
one horsepower is 33,000 footpounds of work done in a minute.
ok so if 100 lb ft of torque is applied to a rotating object at 2000 rpm, then it would be 100 x 2000 / 5252 which would be 38 hp.......
ok so now my head hurts really realy bad....but all in the name of helping others.....i need to take a nap now

RE: Tq vs. hp
These are the articles I always re-read, specially when dyno graphs are given to see how good/bad the numbers are...
http://www.straightdope.com/mailbag/mhorsepower.html (good comparison using two engines tq/hp graphs)
http://auto.howstuffworks.com/horsepower.htm (more horsepower history)
http://science.howstuffworks.com/fpte5.htm (a dyno comparison beween a C-12 Caterpillar vs. Mustang Cobra engine)
Enjoy......
