Bandini 750 sport internazionale

The "Bandini 750 international sport" also called simply "Saponetta", is a racing car built from 1957 until 1961 by Bandini Cars.

This new type of car, prepared for the 750 sports category, replaced the production of the "Sport Torpedo". The adjective "International" pays tribute to the merits collected overseas by the 750 sports torpedo, while "Saponetta" (little bar of soap) was its nickname courtesy of Ilario Bandini for its form, similar to that of a simple bar of soap.

As the model which replaced the bar of soap, it was much in demand in the USA where it was used both as auto racing that as "out of range" to be submitted to the streets in the city. Its debut in racing dates back to Mille Miglia, 1957 led by Bruno Garavini, with a 750 cc Bandini-Crosley (second series) updated especially in the Head (identifiable by the distributor mounted between the two camshafts and the cam covers inclined at 45° with pronounced longitudinal ribs).

The "Saponetta", maintained the characteristics of simplicity and lightness while improving road holding and reducing drag, features which were exploited in motordromes such as the famous Daytona circuit and the high-speed Track of Monza.

The story

((Also see Ilario Bandini)) Despite not lacking in success in the USA, uphill races, and Italian circuits, the " little bar of soap" quickly responded to rapid changes in regulation, giving rise to 850 cc and then 1000 cc versions. These updates proved fast and successful, able to sustain high RPMs even with higher displacements, collecting victories up until 1965 with Gene Parsons, James Eichenlaub (both ex aequo vicechampion U.S. SCCA in 1958), Dave Lang (third in the final classification 1961 with only four races: three first and second place), Skip Callanan, Paul Richards, Victor Lukens, Jack Connolly, Giorgio Cecchini, and Ilario Bandini. These later wins were most impressive, given that many car competitors had mid-rear engines, a choice destined to spread throughout motorsports. In this context, the most important results are third place to Trento-Bondone in 1964 (valid for the European championship mountain) and fourth place to Mugello circuit road, 1965 (Round of World Championship sport cars) both times driven by Antonio Benelli.

750 international sports museum in Los Angeles

Today, nine "Saponetta" remained, one is exposed to the museum Marconi Los Angeles, two are stored in the museum Bandini Forlì.

The chassis

Two frames of Saponetta.

The chassis construction of the Saponetta, while using the same elements as in the "750 Torpedo", changes in size and weight distribution. Increased wheelbase and track width, significantly reduced ground clearance, and considerable lowering of driver position were all accomplished. The engine compartment was enlarged, allowing the housing of the subsequent 850 and 1000 cc engines. The rear suspension has been enhanced with an anti-roll and, in some cases, replaced with independent rear suspension.

Engines

The Saponetta was born with the engine Bandini-Crosley 750 cc but from 1959 was also used with engines 850 cc and 1000, the first engines built completely with Bandini the transmission chain, whose project is dated 1955. There are also copies that are running with engines Saab and Ford.

The body

The bodywork in aluminium open two-seater (little boat) are built in Forlì by Bandini. Since the first copy to the type, have undergone radical changes also in the queue: in the first version appeared laterally two vertical fins, some have a truncated tail, in the final model is elongated, low and clean. The front instead appears definitive if not minor differences in the form of air-intake front, a composition of an ellipsoid and a half circle. Significant between a model and the other is the air vent hot side of the engine compartment, sometimes rectangular smoothed trapezoid, parallelogram single or double. Always an air directed inside the (cylindrical opening with about half side) characterizes the car with which he ran Ilario Bandini. It varies considerably height or shape of windshield while a mobile bulkhead may be mounted on cockpit to reduce aerodynamic drag. The same attention was paid to the rear wheels that could be covered half a removable bulkhead. In this respect is curious to see how the rule which introduced the use of roll-bar may have been exploited to create a fairing which seems to have the function of a wing.
