I remember back in the 90s when Bob Glidden got caught cheating. He won more pro stock races than any other driver in NHRA history. His son Bill ratted him out, What Bob had done was pressurize his roll cage/chassis with NOS and had a small tube built into his hood and hood scope that would mist NOS down into the carbs, which was good for about a 1/16, 1/8 second which is a lot in that class that is usually determined by the driver's skills. Motorsports are notorious for cheating, Richard Petty was good at it.
It wasn't Bob that used the nitrous. It was his son Rusty that did it to prove it could be done. Bob was accusing the Dodge boys of using it amongst others.
