A former editor of Car Craft and Hot Rod, and himself a racer, Baechtel sets out and explains calculations of such matters as engine displacement, compression ratio, torque and horsepower, intake and header size, injector sizing, and piston speed. In many cases, measurement required is illustrated with photographs. Tables, graphs, and drawings are also provided to help automobile mechanics get through the mathematics part of the task quickly and get back to the fun part. There is no index.
