"...the book is tremendously interesting, whether you design engines, tune them for racing or restrict your activities in the gas flow field to an occasional quarter of a turn on the idling-adjuster screw. The author has collected a wealth of information, some previously published in book form, but most culled from papers to learned societies, and made the whole thing easily understandable. There has long been a need for a book of this kind, for the power gains to be earned by proper intake and exhaust systems are substantial, and very few have known exactly how gas likes to travel and what kind of pressures are involved...The basic text is fully applicable to all internal combustion engines."
