Non veni pacem mittere, sed gladium.
That my friend is a fire burnout. Used to see these from time to time back in the 70's at OCIR when I was a kid. They put down some gasoline or kerosine and light it at the start of the burnout. This super heats the slicks for better traction, and put on a show for the crowd. Obviously the NHRA does NOT allow you to do this today.
Yeah, they were awesome and looked just like that. The noise and pressure of the exhaust, the smell of the nitromethane, the sight of the flames all combined in a wonderful sensory overload. Much better than the bleach burnouts!
You mileage may vary.
Once they figured out that burnouts not only cleaned the tires but also made the car leaver harder they started putting dowm bleach which ignited. Wasn't long before NHRA mandated water only for burnouts. No fun in those guys ever!
