Sorry David, you have it backwards.

James Watt was trying to avoid being accused of cheating, therefore his 
definition of horsepower is actually 1.5 times greater than a "real" 
horsepower (what a horse can pull). So what we call 100 hp nowadays, is 
actually 150 hp if you measure in "real" horses.

It's a bit counterintuitive, because it's just like putting lead in weights. 
You buy 1.5 lbs of apples for the price of 1 lb.
