It's a well-known fact that the key to power is the management of airflow throughout the engine, from initial intake to final exhaust. Airflow expert Harold Bettes has compiled decades' worth of research into a user-friendly guide that explains the complex ins and outs of engine airflow with real-world performance applications. Included are sections on- Horsepower defined Engine airflow relationships Internal combustion engine operation Testing engine components How flow benches work Flow testing standards Calibration issues and atmospheric effects Intake and exhaust tuning Tools for measurement and for modification Graphical analysis How to analyze flow bench data Engine formula for performance From a basic overview of how internal combustion works to advanced performance modification and flow bench testing, Engine Airflow gives you the foundation to build or tune any engine for any performance application.
