THE SUPERCHARGED B.N.C. AN INTERESTING FRENCH CAR WITH GUARANTEED SPEEDS.
THE B.N.C. light car, which has an excellent name in France, is a very good example of the sporting type of car so popular in that country. The supercharged semi-racing madel is sold with a guaranteed speed of 1031/2 m.p.h., and, as the photograph shows is a well finished production. The four cylinder engine has a bore of 62 mm and a stroke of 90 rum, giving a total cubic capacity of 1,088 c.c. The engine which is rated at 8 h.p. gives 62 h.p. on the brake. A Solex carburettor is fitted and the supercharger is driven off the crankshaft at the forward end.
The Chassis appears to be much stronger than the average car of this type, and is no doubt built to stand the strain of long road races, such as the Le Mans 24 hours event. Transmission is by means of a three forward speed and reverse gearbox and an open propeller shaft. The brakes are servo operated Perrot type, and are interconnected and fully compensated. The springing is by semi-elliptic springs both front and rear, and the axle is underslung and not fitted
with a differential. As a result the driving position is extremely low. The radiator is inclined, and by this means the makers claim more efficient cooling. It is mounted on silent block bearings so as to eliminate all vibration, etc.
Rudge Whitworth wire wheels are fitted and the spare is carried on the side of the body.
The unsupercharged model Monza type is fitted with a Ruby engine which is specially made for B.N.C.’s. Contrary to the usual Ruby practice this engine is fitted with a water pump. It was this model which won the 1927 Bol d’Or, and in 1928 the Le Mans 24 hour race, beating the worlds record for its class for the 24 hours and covering 2,270 Kilometres in that time. It is guaranteed to attain 78 miles per hour. A very attractive range of bodywork is provided by the manufacturers whose address is : AUTOMOBILES B. N.C. , 90 Rue Edouard-Vaillant, Levallois-Perret,
