This excellent engine theory book was done in 2007, but it still contains some of best information available on advanced theory and design for racing engines. It was produced by Circle Track Magazine with contributions from noted racing authorities like Smokey Yunick, Jim McFarland, Chuck Jenckes and Dick Wells. There’s no regurgitated filler between the covers of this book; just solid racing engine facts and recommendations. It covers all the major topics of racing engine preparation and a full complement of engine theory topics that will change the way you think about race engine design and assembly.
The book contains 24 chapters that formerly ran as individual stories in Circle Track Magazine covering every aspect of competition engine building. It begins with a basic discussion of torque and horsepower; stressing the importance of matching the power band to the application. Moving on it covers race engine basics beginning with the bottom end in detail, block selection and prep, honing, crankshaft prep, rod theory, piston top science, reading combustion patterns and the importance of each to an engine’s net torque output.
Other chapters provide particularly descriptive insight into selecting and tuning intake manifolds and carburetors for specific applications. Then they delve into header tech, power mufflers, oiling system tech, water pumps and cooling theory, engine airflow patterns, cylinder heads and valvetrain in great detail. The books refreshing approach clearly draws from a wealth of Sprint Cup and other late circle track racing knowledge provides numerous tips and tricks employed in these top professional racing series.
The book has been around for a while, but it is well worth tracking down a copy. It puts some of the best racing engine articles by acknowledged engine experts all in one tidy package that will serve racers and engine builders with value far beyond its cover price. A lot of books devote considerable space to parts and piece, but this one acknowledges the broad availability of good parts and then explains how to choose and match them to obtain the best results possible.
