The Science of Intake Design Part 3: CFM vs CSA, X-Pipes vs H-Pipes & Surface Finish #cars

Dive deeper into advanced induction science with Jake from Bain Racing in Part 3 of our comprehensive intake design series. This episode explores the critical relationship between CFM (Cubic Feet per Minute) and CSA (Cross-Sectional Area) and how they directly impact air velocity - the key factor in performance induction systems. Learn the scientific differences between X-pipe and H-pipe exhaust configurations and understand how surface finish (Ra) measurements affect flow characteristics throughout your induction system. This video covers: Why comparing CFM numbers without considering CSA can be misleading How to calculate optimal air velocity for your specific engine application The physics behind X-pipe vs H-pipe scavenging effects Surface finish (Ra) measurement and its impact on boundary layer dynamics Real-world testing data supporting theoretical concepts Common misconceptions about intake and exhaust flow For engine builders, tuners, and automotive enthusiasts who want to understand the deeper science behind intake and exhaust system design. Join Jake from Bain Racing as he shares advanced fluid dynamics concepts in practical, applicable terms for your performance engine project.
