The White Triplex (also known as the "Triplex Special" and the "Spirit of Elkdom") was an American land speed record car built for J. H. White and driven by Ray Keech. It was powered by three 27-litre Liberty aero engines, for a total of 36 cylinders, 81 litres of displacement and a claimed 1500 bhp.
White, a wealthy American from Philadelphia (unrelated to the White Motor Company), wanted to take the land speed record from the British, then shared in a duel between Henry Segrave and Malcolm Campbell.
No suitable engines were available to give a sufficient advantage over the British Napier Lion, so the simplest possible chassis was constructed and three war-surplus Liberty aero engines were squeezed into it. The vehicle was simple, with no clutch or gearbox and only a single fixed ratio. Once running by a push start, it had to keep rolling. Driver comforts were minimal: the forward engine was sheathed in a crude attempt at streamlining, the two side-by-side behind it were bare, with the driver perched between them and the one in front.
An established motor-racing driver, Ray Keech, was engaged to drive. Initial trial runs were hazardous, with Keech being injured by burns during both: first from a burst radiator hose, then by exhaust flames from the front engine.
The simplicity of the design also led to a farcical situation with the official scrutineers. The regulations required "means for reversing", which the White Triplex did not have. Mechanics first jury-rigged an electric motor and roller drive onto a tyre, but this was unable to rotate against the compression of the three large engines, which could not be un-clutched. An even more complicated contrivance was tried, an entire separate rear axle was fitted, held above ground until dropped by a release lever and then driven by a separate driveshaft. The device is not believed to have been fitted during the record attempt itself, but it satisfied the scrutineers.
On April 22, 1928, Keech set a new land speed record of 207.55 mph (334.02 km/h) at Daytona.
This record was raised to over 230 mph by Henry Segrave in Golden Arrow on March 11, 1929. Keech was asked by White to drive again, this time at Ormond Beach, and to re-break the record in the Triplex. Keech declined, considering the car to be too dangerous. White then hired their team mechanic Lee Bible, a garage owner with no experience driving at these speeds.
