but to further a simple explanation... overlap helps improve intake port flow by utilising scavenging effect with exhaust pressure waves.... to understand this, you must understand how the internal combustion engine works, and to understand scavenging, you must have a basic understanding of fluid dynamics

you don't have to be an engineer to have a good enough understanding to make a faster car, but you do need to learn and understand enough to do this... so like I said, those books will really help you learn
