Why the heck you think its 'bout then if its not airflow? Bore, stroke, rod ratio, head(s), combustion chambers, valves, valve train, cams, intake, exhaust all have to do w/ air velocity= airflow. Think of the motor being a pump. The rpm's fall where they fall. I'll take a motor that'll make max power at 6000 than at 8000.
