How come the horsepower rated by Ford (with the mustang for instance) appears to be less than what most people would say is actually generated at the wheels?
The 2002 GT is rated at 260 "horsepower" by Ford.
It is confusing especially when shopping for a supercharger, some companies claim 130 "horsepower gain" and others, claimng to sell virtually the same product claim only 70 "horsepower" gain.
So, is it, for example, 70 "horsepower" on top of the 260 hp Ford rating to result in a "horsepower" of 320; or is it some other figure?
and then the different acronyms dont help- bhp, sae, rwhp,hp (some are self-evidence others not so)
