See those little metal tubes around the top? They are injecting Nitrous Oxide to make ridiculous horsepower. An internal combustion engine can only accept as much fuel as it has oxygen to burn it. You can put on a turbocharger or supercharger to increase air pressure(more oxygen) into the engine so it can handle more fuel and make more power. And/or add NOS which when added to the incoming air cools it, making it more dense, plus adding extra oxygen. However when it ignites before it reaches the cylinders the results are catastrophic. The NOS is injected as a liquid, but if some between the pressure tank and the engine has become vapor in the feed lines, an explosion is likely. I've seen a simple NOS system backfire and melt out the entire center of a large 4 barrel carburetor in a heartbeat.
