1924 Hisso/Wright - Martin E-4
Meticulously restored by my father, nothing was left untouched.
The engine is undergoing dynamometer testing in this exercise. She passed with Flying Colors.
History:
With the start of World War I, Hispano-Suiza turned to the design and production of aircraft engines under the direction of Marc Birkigt. His chief engineer during this period was another Swiss, Louis Massuger. Birkigt's solution to building aero engines was ahead of its time. Traditionally, aircraft engines were manufactured by machining separate steel cylinders and then bolting these assemblies directly to the crankcase. Birkigt's novel solution called for the engine block to be formed from a single piece of cast aluminum, and into which thin steel liners were secured. Manufacturing an engine in this way simplified construction and resulted in a lighter, yet stronger more durable engine. Thus, Birkigt's new construction method created the first practical, and what are commonly known today as, "cast block" engines. His aluminum cast block V-8 design was also noteworthy for incorporating overhead camshafts, propeller reduction gearing and other desirable features that would not appear together on competitor's engines until the late 1920s. Hispano-Suiza's aero engines, produced at its own factories and under license, became the most commonly used aero engines in the French and British air forces, powering over half the alliance's fighter aircraft.

Que maravilla😊
What did it dyno at? The Wright built version was rated at 300 HP @ 1750 RPM!
that is no good for exhaust valves
Do you think that the 6 inch zoomies (that we didn't have) would make a difference though? This engine is still running perfectly fine with 6 inch exhaust stacks (zoomies).
Lower octane fuel? Probably designed for about 85 octane.
