to perform better than others
Better in what way? Whenever something is made "better" a price has to be paid elsewhere ie made worse. Big horsepower may give you great payload lift or high altitude capability, but at the expense of increased fuel consumption and reduced range. Mine would have been "better" had it been fitted with adequate ventilation, nothing more, it ran out of puff at high altitude or high temperatures, but since we were a sea level operation in mild temperatures it mattered not. On the plus side, because the engines were operating at high power in the cruise fuel economy was great.
