Power Unleashed Trailblazers Who Energised Engines with Supercharging and Turbocharging

Award-winning author Karl Ludvigsen takes the reader behind the scenes of the roller-coaster ride of supercharging, turbocharging and even more exotic power-boosting inventions throughout automotive and aviation history. Supercharging in all its forms is the most exciting feature ever created to go under the bonnet of a motor car. Blowers were rare yet highly desirable devices in their early heyday of the 1920s and ’30s, an era in which compressors graced supremely glamorous and race-winning cars. They also won respect from aviators eager to exploit high altitudes.

Prolific use of forced induction in the air in World War II brought forth the many engineering geniuses who populate these pages. Having seemed abandoned on land, supercharging found new acolytes who perfected blowers for road and track. They rescued the turbocharger to open new avenues for high-pressure boosting in the 1970s and ’80s. Into the 21st century turbocharging has found its way into more and more cars to enhance both performance and fuel efficiency.

Power Unleashed is a three-volume work of astonishing depth and detail. Greatly respected for his ability to communicate information while telling a compelling story, Karl Ludvigsen explores the global saga of supercharging and turbocharging. Complete with reader-friendly technical descriptions and magnificent illustrations, he introduces the fascinating individuals who bet their businesses on boosting. This is a landmark work in the histories of the automobile and aeroplane.
