High-performance Cams & Valvetrains: Theory, Technology, and Selection - Softcover

Über die Autorin bzw. den Autor

Growing up on a rural Mississippi farm, Billy Godbold had two passions: science and internal combustion engines. He had the opportunity to combine those passions into one career after receiving his Master of Science degree in physics from Florida State University. Billy has worked with legends (Glidden, Lingenfelter, Jenkins, Pink, and Elliot) and eventually began consulting with today's most highly engineering-focused NASCAR teams and original equipment manufacturers. Billy's unique background allows him to communicate complex concepts in a way that anyone can understand. During his time with the valvetrain group at Comp Cams and Edelbrock, Billy developed the Xtreme Energy, Thumpr, and XFI camshaft lines. Billy's designs and leadership have helped customers win thousands of professional-level races and hundreds of championships.

Camshafts are the coach and conductor of any four-stroke engine from early flatheads to modern Formula 1. Performance engines are amazingly sensitive to how and when the valves to the combustion chamber open and close. The valvetrain configuration and flow characteristics may change significantly between applications, but the fundamental principles are universal. This allows the language, setup, dynamics, energy, and pressure aspects of a valvetrain to be covered in a way that is just as useful for optimizing a sub-15-hp go-kart engine as it is on a 500-plus-hp street engine or a modern 1,500-plus-hp NHRA Pro Stock engine.

In High-Performance Cams and Valvetrains: Theory, Technology, and Selection, farm-kid-turned-physicist Billy Godbold combines his quarter-century of experience with valvetrains at Comp Cams, Lunati, Crane Cams, and Edelbrock with the techniques he uses with professional teams in NASCAR, the NHRA, road racing, dirt-track racing, offshore racing, and land speed racing. He guides you to think about any valvetrain system with his perspective. Often lighthearted and filled with analogies, this book endeavors to make complex concepts easy to understand without watering down important details.

Specific configurations and applications are covered, providing techniques and examples for optimizing camshafts and the valvetrain around intakes, headers, superchargers, turbochargers, fuels, carburetors, and modern EFI applications. If you are planning or building a performance engine, or if you just want to know the science behind how cams and valvetrains work, this book is an indispensable resource.
