Haynes Bentley 4 1/2 Litre Owners’ Workshop Manual

The 4 1/2 litre Bentley is one of the most iconic pre-war cars, and the super charged 4 1/2 litre "blower" Bentley is today one of the most sought-after and most valuable cars for collectors.

The "Bentley Boys" won several high-profiles races in Bentleys, and Woolf Barnato and Bernardo Rubin won with a 4 1/2 litre car in 1928. Five supercharged "Blower" Bentleys were built to compete at Le Mans, but the car's Achilles Heel was its reliability, and it never won the 24-hour race.

This Manual provides details of the 4 1/2 litre unsupercharged and "Blower" Bentley racing cars, detailing their period racing history, anatomy and engineering, and provides an insight into owning, maintaining, and running an example of this iconic card today. Illustrated with period photographs and design and engineering material, plus photographs of restored examples in use today.
