Ten years after 1st flying, the DOHC/4V Napier Lion W12 had doubled in power, ( & in compression ratio*),
to enable a splendid win in the renowned Schneider Trophy International, & at record speed.
Another decade later, the now venerable Lion would also power Cobb-Railton's World Land-Speed car,
(in supercharged form, & at 3X its original power rating), to take, & duly hold, that title - up to the 1960's.
*See the following page in the linked article for the effect on power output via fuel/comp-ratio values.
