Analysis of information sources in references of the Wikipedia article "Desmodromic valve" in English language version.
In 1910 Herbert Austin decided to build a Marine engine that at the time was very advanced. It produced 300bhp and was installed in a speedboat called "Irene I" which was named after his eldest daughter who had married Colonel Waite. The all aluminium twin ohv engine had twin magneto, twin carburettor and desmodronic valves.
Thus, neglecting all other factors, the faster an engine can be made to turn, the more power can be generated. Unfortunately, through at least the 1950s, valve springs often would fatigue and break when engines were operated for significant periods of time much above 8000 rpm.
