Although of small engine capacity, they were frequently supercharged to increase performance. Never as fast as the aero-engined land speed record behemoths driven by the likes of Henry Segrave, they set numerous speed records for their engine capacity class.
In search of even faster speeds, it was decided to supercharge the car, using Eyston's own Powerplus design of supercharger. In February 1931, again at Montlhéry, this became the first 750cc car to exceed 100mph, at 103.13mph.
After this success, MG were prompted to produce a racing replica of it: the C-type or Montlhéry Midget, which was available with or without supercharger.
Eyston was never satisfied with merely reaching a speed when he could use the same car to break several records by maintaining it for longer periods. He set out to hold 100mph for an hour, using EX120. The car reached this speed, but then the engine caught fire. Still at a speed of around 60mph, the Eyston's tall figure manged to jump from the tiny enclosed cockpit, counting on his past fox-hunting experience to roll through the landing without serious injury. The car was destroyed, and Eyston then filed another of his many patents for fire-proof asbestos overalls.

In 1935 Eyston sold it to Goldie Gardner, who then had Reid Railton re-design another bodyshell for it. (reprinted in p74, )
