What if an engine could deliver the power of something much larger without adding another cylinder or increasing its displacement? For more than a century, turbocharging has challenged the traditional rules of engine performance. What began as an ambitious attempt to recover useful energy from exhaust gases became one of the most influential developments in automotive engineering, transforming racing machines, diesel engines, performance cars and eventually millions of ordinary family vehicles. Boost Changed Everything traces that remarkable journey, from the early industrial experiments of Alfred Büchi and the pioneering American turbocharged cars of the 1960s to the BMW 2002 turbo, Porsche 911 Turbo, Saab’s practical innovations and the turbocharged performance revolution of the 1980s. It explains how turbines, compressors, intercoolers and wastegates work, why turbo lag occurs, and how advances in electronics made powerful, smaller engines increasingly practical. The story continues through the rise of turbodiesels, the downsizing movement and the complicated relationship between boost, fuel economy and emissions. It also explores modern twin-scroll and variable-geometry turbochargers, multi-turbo systems, electrically assisted boosting and the changing role of turbocharging in hybrid and electric motoring. Written in accessible language and combining engineering with automotive history, this book reveals how a relatively small mechanical device transformed the way engines produce power and how cars feel on the road. From racing circuits to everyday journeys, discover how turbocharging changed the automobile.
