"The Secret Horsepower Race: Western Fighter Engine Development Hardcover
by Calum E. Douglas (Author)
The piston engines that powered Second World War fighters, the men who
designed them, and the secret intelligence work carried out by both
Britain and Germany would determine the outcome of the first global air
war.Advanced jet engines may have been in development but every
militarily significant air battle was fought by piston-engined fighters.
Whoever designed the most powerful piston engines would win air
superiority and with it the ability to dictate the course of the war as
Its an incredibly detailed work complete with engineering drawings of
the engines and internal workings of the design bureaus in the UK ,
Germany and USA regarding the engines that would power the warplanes of WW2.
What is surprising is that German and British engine design groups were
talking to each other pretty openly right up to the end of 1938. Rolls
Royce visited Daimlet Benz and vice versa.
The major US conributions were in the field of spark plugs,
superchargers and fuel development, especially 100 Octane gasoline which
it also covers quite thoroughly.
The Germans were ahead of the curve with fuel injection.
