DEVELOPED BY THE AMC race shop for the 1939 Senior TT, the formidable Supercharged V4 was built to respond to the supercharged Italian and German factory racers dominating the TT and Grand Prix circuits at the time. It was the first machine to lap a Grand Prix course at over 100 mph (161 km/h).
The parallel-twin blocks were arranged in a 50° V-layout with chain-driven single overhead camshafts. The supercharger lay across the front of the magnesium crankcases. The outbreak of war prevented racing victory in 1940, and supercharging was banned in 1946 by the Auto Cycle Union (ACU).
