Speed of the Wind
Speed of the Wind was a record-breaking car of the 1930s, built between 1934 and 1935 and driven by Captain George Eyston.
The car was designed by Eyston and E A D Eldridge, then built by the father of Tom Delaney It was powered by an unsupercharged version of the V-12 Rolls-Royce Kestrel aero engine. The car was too large and heavy for circuit racing and was already underpowered by the standards of the absolute speed record breakers. This car was designed for endurance, more than peak power. Running a supercharged engine with the fuel and materials technology of the day would never have lasted the duration. This particular engine was obtained second-hand from Rolls-Royce, where it had previously powered an airflow fan in an engine test cell. Having always been intended for long-term use at ground level, it had been built without the Kestrel's usual supercharger.
For streamlining, distinctive features of the car are the two small "nostrils", headlights and air inlets in the nose. These produced less drag than a typical inlet and flat honeycomb radiator. The engine was cooled instead by a surface radiator wrapped around the top of the bodywork, just in front of the driver.
During testing, the car appears to have run, although not competitively, at either Brooklands or Montlhery.
Records
Speed of the Wind was built for long-duration speed records, which were the domain of Ab Jenkins and the Bonneville salt flats of Utah. Jenkins was fond of competition and was instrumental in encouraging British teams to travel to Bonneville.1935
In September 1935, shortly after Campbell's 300 mph record with Blue Bird, Eyston broke Jenkins' 24-hour record and raised it to1936
For the 1936 season, Jenkins created the Mormon Meteor by fitting a Curtiss Conqueror V12 into his previous Duesenberg chassis. Eyston returned, with E A D Eldridge as team manager, and his colleague from Brooklands, John Cobb in the Napier-Railton as another competitor.Eyston set the first records, averaging for 24 hours and over 48 hours.
The Mormon Meteor made its first attempt, beating the average speed to 12 hours at, but retiring with a driveshaft failure. John Cobb then took Eyston’s 24 hour record at, but didn't attempt 48.
The Meteor made a second attempt, and this time remained reliable. Its two co-drivers set times of for 24 hours and for 48.
