I say the worst moment for me was when I was at the drag strip with my 84 VW Rabbit. During the day I switched the nos from 50 to 75 shot thinking the engine could handle it. So when the light turned green and I pushed the button BOOM the entrie front of the car caught fire for a few secs from a mix of fuel and oil. What was even more funny when I opened the hood a piece of my piston was jamed in the radiator. Everybody was like damn.
