Bentley Blower is amongst the most iconic fast cars ever made in the 1920s for a race track. This 4.5-litre model was made specifically for race track endurance and proved to be highly reliable in the 1928 Le Mans. However, a jammed wheel in the 20th lap made it miss taking home the race’s victory. The car later dropped the 4.5-litre engine and opted for a bigger 6-litre engine.
A Supercharger on Board
Bentley at first did not believe in adding superchargers to engines. In fact, he claimed that adding engine sizes was even more efficient. Sir Henry ‘Tim’ Birkin with financial backing from Dorothy Paget rebuilt the car including a supercharged engine. This addition on the Bentley Blower would later assist in winning the 1930 French Grand Prix race. Since then, supercharged and turbo engines rule racetracks all over the world.
Specifications of the Blower
The original version of the Bentley engine produced approximately 130 bhp. With the help of Amherst Villers and strong financial backing from Dorothy Paget, Engineer Sir Henry ‘Tim’ Birkin rebuilt a car with 242 bhp output. The Roots-type supercharger was connected straight to the crankshaft. It gave the car a unique appearance. This then gave birth to the 242 bhp ‘Blower Bentley.
Never Made it to Le Mans
Birkin produced about 54 cars in the lifetime of this racing power horse. The Blower, however, had one weakness. Its chassis was a bit fragile and couldn’t last a race. For this very unfortunate reason, the Bently never won at Le Mans, the very reason it was built. It however won the GP race.
