F1 cars also do it but you never see it cuz methanol fire is invisible. WRC cars prolly do it the most because its their anti-lag system. Basically unburned fuel goes past the engine and ignites before the turbo causing it to spool up much faster. Makes you wonder why a 2.0 engine that makes about 350 Hp turbocharged churns out more then 500 Lbs of torque. Its usually a highly tuned turbo'd car that makes a flame.
