To estimate your own car's horsepower, take the stock hp rating, and add in the highest estimated power gain from each mod you have done. To estimate the horsepower of an American car, take its stock horsepower rating, and deduct 10 to 25 hp for it being a POS. Make no adjustments for mods. Remember, Japanese horsepower is better quality than the horsepower found in an American car. If you don't know how much horsepower an American car has, assume it has either 30 hp per liter, or 200 hp, whichever is less
i see no flaw in this arguement
