Air flow and efficiency determine how BIG a motor is, how much air it can move efficiently is generally more important than static displacement. And we're just talking naturally aspirated here....Turbos are a whole 'nother level and less, generally speaking smaller/lighter engines are more thermally and volumetrically efficient overall.
this point a few people always seem to forget,
Truth has no agenda, but those with an agenda make their own truth. Some of us are so open minded they only see their View
