This is one of the best-selling technical books in its field. For years, engineers, engine designers, high-performance tuners and racers have depended on this book to help maximize their engines' potential. Dr. John C. Morrison is one of the foremost authorities on the analysis of the induction and exhaust processes of high-speed engines. Together with Philip Smith, he gives a thorough explanation of the physics that govern the behavior of gases as they pass through an engine, and the theories and practical research methods used in designing more efficient induction manifolds and exhaust systems, for both competition and street use. An outstanding, authoritative book.
