Fiat Mephistopheles SB4 Eldridge
SB4 Eldridge Fiat "Mephistopheles", a car racing is built on the modified chassis of a Fiat SB4, 1908 that has been transplanted in an aircraft engine, built in 1924 by Ernest Eldridge.
The name Mephistopheles was attributed to the cause of the infernal noise of the engine exhaust emitted by its free.
History:
In 1922, Ernest Eldridge, an eccentric English lord, purchased the scrap of an old Fiat SB4 of 1908 severely damaged in a racing incident, with the intention of making a sports car to beat the speed record.
Ernest Eldridge was able to install on his SB4, a propeller aircraft Fiat A 12 six-cylinder in-line to 21,706 cc, improving the power system, achieving the power of 320 hp.
To install the motor 12 A, Eldridge had to change the frame of the SB4 stretching from parts of the frame taken from a bus. The body of the SB4
amended, improved style than the original, making it very sleek with a nice tapering of the tail. The mechanics of
SB4 Mefistofele rimase quella della SB4 originale con trasmissione finale a doppia catena. e freni posti unicamente sull'asse posteriore.
Il risultato è un mostro di vettura a 6 cilindri da 21706 cc4 candele e 4 valvole per cilindro, albero a camme in testa4 carburatori, rapporto di compressione 4,8:1
La potenza è quella del motore di origine 320 cavalli, la vettura ha un peso di circa 18 quintali, sospensioni ad assale rigido con balestre all'avantreno e al retrotreno.
Con questa architettura e la notevole potenza del motore lascia intuire quanto sia difficile tenere in strada questa velocissima vettura, SB4 Mefistofele, veramente un diavolo di macchina.
Infatti, alla guida della Fiat SB4 Mefistofele, il 12 July 1924 Arpajon in France, Sir Ernest Eldridge won the world speed record, reaching 234.98 km / h. No other driver besides
Eldridge was able to lead and dominate the SB4 Mephistopheles
Anyway, it is he who created the big, powerful car.
Fiat SB4 Eldridge was named Mephistopheles , due to the tremendous noise from the engine exhaust with free, Fiat Mephistopheles SB4 Eldridge was an infernal machine.
also competed in the same competition with René Thomas Delage V12 engine with 350 hp, Eldridge during the first race with the Mefistofele SB4 reached the speed of 230.55 km / h, an absolute record.
The team Delage this complaint because the SB4 "Mefistofele" was devoid of the reverse, as was stipulated in the regulations and the record of Eldridge was not recognized as valid.
The next day, René Thomas was able to bring their own Delage V12 at a speed of 230.63 km / h, a record which was duly approved. The primacy of
Delage lasted just six days, the time it takes to Eldridge to develop its SB4 Mephistopheles, and to add a system that pulled the backing.
On 12 July 1924, Sir Eldridge led his SB4 "Mefistofele" at the world speed record of 234.97 km / h and was the last world record for the flying kilometer to be achieved on the road.
