The Science of Intake Design: Primary Length, CSA & The Secrets to Maximum Horsepower #cars

Dive deep into the engineering behind performance intake systems with this comprehensive guide for engine builders and tuners. Jake from Bain Racing breaks down the critical science of induction systems - from primary runner length calculations to cross-sectional area optimization and beyond. Learn how to properly size your plenum, calculate optimal runner lengths using quarter-wave tuning principles, and understand the real physics behind inertia supercharging. Whether you're building a street performance engine or a dedicated race application, these fundamental principles will help you extract maximum power and torque across your desired RPM range. This video covers: How to calculate optimal primary runner length for your target RPM Cross-sectional area (CSA) formulas and their relationship to air velocity Plenum volume recommendations for different applications Quarter-wave tuning and pressure wave dynamics Line of sight principles for maximum flow Common induction design mistakes to avoid Real-world examples and calculations For engine builders, tuners, and automotive enthusiasts who want to understand the science behind intake design rather than just following rules of thumb. Join Jake from Bain Racing as he shares proven techniques from years of performance engine building experience.
