Description of the original vehicle:

The Alfa Romeo Tipo B was the most successful single-seater Grand Prix racing car of its time. Alfa Romeo built and raced it between 1932 and 1936. Initially as a factory race car for Alfa Corse, then later under the Scuderia Ferrari label after having taken over Alfa Romeos racing activities. The car, designed by the legendary engineer Vittorio Jano, was based on the equally legendary Alfa Romeo 8C models. The P3 was Alfa Romeos second single-seater after the Tipo-A monoposto of 1931.

The chassis with longitudinal spars and cross members made of pressed steel C-sections, derived from that of the Tipo A, was adapted to the regulations and modified to accommodate the new engine. This version of the engine had a larger displacement of 2654 cm³ (bore × stroke: 65 × 100 mm) than the turbocharged in-line eight-cylinder engine of the 8C 2300 “Monza”. It was advanced for its time, with a light alloy cylinder block and head split into two halves, each with four cylinders.

Jano divided the block to reduce the torsional vibrations of the crankshaft and camshafts by placing all the power take-offs in the centre of the crankshaft: the drive for the camshafts, on the side the drive for the supercharger fans and opposite on the exhaust side the drive for the pumps for oil and cooling water. The crankcase was in one piece. The engine had dry sump lubrication, two Roots compressors and two Weber carburettors, magneto ignition and water cooling.

It produced 215 hp at 5600 rpm. The four-speed gearbox and the multi-plate clutch were blocked to the engine. The wheels were suspended front and rear on rigid axles with semi-elliptic leaf springs and friction shock absorbers, rear springs and shock absorbers were double.

The drum brakes were mechanically operated. A novelty of the type B P3 was the placement of the differential directly behind the manual gearbox. From there, the power was transmitted to the rear wheels via bevel gear pairs with two diagonally arranged shafts.

The differential being further forward reduced the unsprung masses and the load on the rear axle. This was to reduce the tendency to oversteer and the driver’s seat could be mounted directly on the floor panel in the sense of a low centre of gravity between these shafts.

This 700 kg single-seater with its simple, streamlined bodywork reached 225 km/h.
