There were a total of about 50 production supercharged Bentleys and another five were developed for racing.

Harry Rose is at the wheel of a genuine ex-Paget team car and Russ Turner’s is a modified production car. Both cars were capable of about a 100 mph and remained smooth and flexible to drive at high speed.

The idea of supercharging the big 4½ litre 4-cylinder Bentley was that of Sir Henry ‘Tim' Birkin and, although W.O. Bentley did not approve of superchargers, it became a production car.

Birkin formed his own racing team, to race the supercharged cars, but these were not as reliable as the standard Bentley team cars.
