What a retarded argument...
If it's anything like what Stillen advertises, it is estimated BHP. Which is useful for people paper racing based upon the stock 332 BHP figure. It's actually safer to state the estimated crank horsepower output of a kit since dyno and atmospheric conditions vary so widely. 500 BHP can very well end up just over 400 WHP on a low-reading Mustang dyno.
