How many cc in one horse power?

There is absolutely no direct correlation in horsepower and CC's. CC's is the engine size or displacement, whereas horsepower is the output generated by that engine. Horsepower can vary for a given engine based on altitude, temperature, and engine condition. If any of these variables change, the engine size or displacement remains constant, however, the output (horsepower) can vary significantly. To the person that says his honda engine is a x-horsepower with so many CC's, thus there are xx number of cc's in a horsepower, he is only correct when that particular engine is operating, at ideal standards equal to that of the manufacturer.
