rFactor 2 – Ferrari 156 F1 ’61 Sharknose project.

Wojciech Gurycz started work on a Ferrari 156 F1 model project for rFactor 2.

The Ferrari 156 was a racecar made by Ferrari in 1961 to comply with then-new Formula One regulations that reduced engine displacement from 2.5 to 1.5 litres, similar to the pre-1961 Formula Two class for which Ferrari had developed a mid-engined car also called 156.

Ferrari started the season with a 65 degrees Dino engine, then replaced by a new engine with the V-angle increased to 120 degrees and designed by Carlo Chiti.

This increased the power by 10 hp (7 kW). Bore and stroke were 73.0 x 58.8 mm (2.3 in) with a displacement of 1,476.60 cc and a claimed 190 hp (142 kW) at 9,500 rpm. For 1962 a 24-valve version was planned with 200 hp (149 kW) at 10,000 rpm, but never appeared.

In 1963 the 12-valve version fitted with Bosch direct-fuel injection instead of carburetors achieved that power level. The last victory for the Ferrari 156 was achieved by Italian Lorenzo Bandini in the 1964 Austrian Grand Prix.

A V-6 engine with 120 degree bank is smoother at producing power because every 120 degree rotation of engine crankshaft produces a power pulse.
