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.

  • Volume 1, “Rushing toward the racing zenith, 1890s to 1950s,” begins by introducing the bold pioneers who first won races with blowers in 1910 and then took to the air to gain altitude with supercharging in the Great War.
  • Inventive ideas for piston-type blowers, Roots-type, centrifugal, screw-type, vane-type, exhaust-driven turbos and other new compressor technologies.
  • How Fiat, Mercedes and Duesenberg vied to be first in racing with blowers in the early 1920s, sparking a world-wide swathe of interest in exotic supercharged road and track cars that also embraced the likes of Alfa Romeo, Bentley, MG, Miller, Sunbeam and many more.
  • As befits its title, “Wartime boost to forced induction, 1930s to 1970s,” Volume 2’s focus is on the huge strides made in supercharging and turbocharging in World War II by Allied and Axis combatants.
  • Post-war, America powered ahead with turbocharging’s proliferation in racing at Indianapolis followed by wider use from the 1970s for passenger cars and racers, most notably Formula One’s 1,500-horsepower projectiles.
  • Volume 3, “Turbo triumphs on road and track, 1970s to 2020s,” introduces the many and varied applications of boosting for petrol and diesel engines through to the present day.
  • Why and how the 21st century sees sweeping conversion of both road and racing cars to forced induction for higher efficiency and the ultimate in road-burning performance.

Car Racing 1971 – Now In Stock!

Alain Pernot & Manou Zurini

Car Racing 1971 is every bit a worthy successor in the tradition established by the six previous tomes of the Car Racing series (1965 to 1970). It is still through treasures unearthed from the archives of the DPPI photographic agency that this book offers, for the title year, a unique experience of immersion in the atmosphere of 1970s motorsport. Created in 1965 by a group of photographers fascinated by the fury of the track and the bravura of drivers, DPPI has always gone where the action is. This proximity resulted in incredible action photos, unimaginable today. ‘This is not an umpteenth book on the history of motorsport,’ insists DPPI director Fabrice Connen. ‘In every case, we favored the strongest, most unusual pictures or those that best recreated the atmosphere of the time, even if they were taken at minor events or depicted less famous competitors.’

About the Author

Manou Zurini was among the first to lend motorsport photography an artistic dimension. Now an internationally renowned sculptor and retired from the racing circuit, he has forgotten nothing of this exciting period and punctuates the pages of Car Racing with his colorful commentary. Alain Pernot is an independent journalist and motorsport expert who knows how to share his exhaustive knowledge with all the passion that drives him to collect it. He is the author of several books about Formula 1 and Le Mans.

Just In: 1/18 2025 Indy Cars from IXO America

IXO America has delivered their first batch of 1/18 scale diecast 2025 Indy Cars. 3 Road / Street course versions seen earlier this year and 3 Super Speedway versions (Santino, Larson & Marco) in their Indianapolis 500 liveries are in stock. Great quality with a low $79.95 price point and with non-Chinese production, not subject to massive tariff up charges if the current thaw takes us back to the brink. Additional cars and drivers (including Palou) are expected soon. 

You can pre-order the entire line HERE.

TopSpeed / TSM Announcement

TSM / TopSpeed have issued their first major new product announcements since the tariff war exploded earlier this Spring, making it virtually impossible to set firm pricing on anything produced anywhere outside the US, especially China, where most quality diecast and resin models are produced.

Most of the prices on the 1/12 scale TSM Ducati motorcycles, 1/18 TopSpeed and 1/43 TSM racing and sports cars listed include the 145% tariff on China exports currently in effect. Almost certainly, that number will change several times before these models arrive in the US, where and when the tariffs will be collected so we expect the final pricing of these models to reflect those changes. Most of the extra cost is being absorbed by the manufacturer, distributors and dealers but bottom line is that models will cost more until this game of chicken ends.

If you’re not comfortable ordering under these circumstances, I truly understand. No one in this business is happy about what’s going on.
