Since this discussion happens so often, as it has, again, on the previous post, it's about time we explain horsepower and torque and how they relate. There are a lot of misconceptions, but there doesn't have to be because both are straightforward terms used everyday when motor vehicles (and a lot of other things) are discussed.
Please read this entire article carefully before commenting. You'll see where that 5252 number comes from and you'll see why you can't talk about horsepower and disregard torque anymore than you can discuss an omelet and ignore the eggs.
You gotta start somewhere, this is a good place.
Every motorhead wants more horsepower, but what exactly IS horsepower? What does it measure? Horsepower is an arbitrary unit created from a common reference point that everyone can understand. In today's world of advanced scientific instruments, horsepower hangs on, even though it is a little imprecise. Those keepers of the units and standards that quantify everything with precision would rather toss out this well known measure and substitute kilowatts. That Corvette has 298.28 kilowatts, hmm... 400hp just sounds better.
Where did horsepower come from?
James Watt, who did quite a bit of work on steam engines back in the 1700's, needed a way to measure their output. Watt used a common reference, the horse, as the basis for his calculations (like the inch was based on the width of a man's thumb). The exact process he followed to find out what a horse could do is open to speculation, everyone seems to have their own favorite story, but the end result was: 1 horsepower = 550 foot-pounds per second, which means, in Watt's calculations, a horse can lift 550 pounds one foot in one second.
