>In 1929 Sunbeam built a 24 litre record breaker named Silver Bullet which became the bane of Don’s life as it continually burst into flames when backfiring through the carburettors, a tendency which was never ultimately cured due to lack of time and resources.
The Silver Bullet using two untested 12 cylinder engines to generate 4,000 hp. When supercharger blowbacks at 190 mph broke compressor blades in the 1930 Daytona Beach land speed record attempt, Don decided that the project was hopeless and abandoned his attempt to break Henry Segrave’s 231 mph record set in 1929.
Driving the V-12 Sunbeam Tigress at Brooklands on 9th June 1930 he raised the Outer Circuit lap record to 137.58 m.p.h. and for the ensuing three years he became known as the driver of a potent and stunningly beautiful red 4.9 litre Bugatti known as Tiger 2.
