Rafal Kochanowski and his BMW 1 Series (E81) compete in the Drift Kings International Series for the TurboWorks Drift Team. The hatchback is powered by a 4.2 L Audi V8 with custom forward exhaust manifolds feeding a single large turbocharger. The engine is tuned by M.Klasa in Poland and makes 1000+ horsepower. Listen to the engine scream as Rafal drifts at RabócsiRing in Máriapócs, Hungary.
