Auto racing is the ultimate test of machinery, where engines are stressed to their absolute max, far beyond what those who designed them ever anticipated. Naturally, that also means that engine failures are a rather routine part of motorsport. Nobody stresses parts like drag racers do, as they generate simply explosive levels of horsepower for very short bursts by packing in massive amounts of potent fuel and oxygen. Needless to say, when drag engines let go, it is nothing short of spectacular.
