Horsepower is a power, and as such relates to work done in a fixed period 
of time. Power is work / time. Effectively, horsepower indicates the 
maximum speed your car could reach, given the proper gearing. The 
horsepower of your car does battle against rolling resistance, drive 
train resistance and air resistance.

Torque is a force acting at a distance. This is why its units are 
something like lbs-ft. To conceptually grasp it, torque is the amount of 
twisting force the engine possesses. This is the important stuff for lbc's. 
The higher the torque, the better the get up and go. 

The horsepower can be calculated by knowing the torque at a given rpm.
