The 1982 race, held at the height of the FISA–FOCA war, was also shrouded in controversy. Rio born driver Nelson Piquet, who had won the World Championship the year before, finished first in a Brabham BT49-Ford, with Finland's Keke Rosberg second in a Williams FW07C-Ford. However, both drivers were disqualified for being underweight, having raced with "water-cooled brakes". This promoted Alain Prost, third in the turbocharged Renault RE30, to the win, the first of an eventual five for the Frenchman at the circuit and start a streak of 7 straight wins for turbo powered cars at the circuit until the original turbo era ended following the season. The disqualifications, however, prompted most FOCA-aligned teams – including Brabham and Williams – to boycott the San Marino Grand Prix two races later. However, unlike the 1980 Spanish Grand Prix where the factory teams of Ferrari, Renault and Alfa Romeo (all who were on the FISA side of the war) boycotted the race and the results were eventually voided, the 1982 San Marino Grand Prix results without the FOCA teams were counted.
