The amazing Megatron BMW M12 F1 engine,there are so many rumors surrounding this engine. The blocks used to build the engines came from used BMW 2002 road cars, because as they had already gone through many heat cycles the stresses in the metal had already been worked out? The blocks were left out side the work shop and the engineers were encouraged to urinate on them as urine contains high levels of ammonia witch contains nitrogen effectively nitriding the blocks making them stronger? What ever you believe about this engine the facts are 1500cc and 1500hp @ 5.2 bar of boost! Incredible.
