Motor, not engine. :-)
Typically, fireballs come off the brushes and strike the arc between conductors (like the brush rigging and a terminal stud.) It this case, we either picked up some FOD from the track (most likely) or we vaporized one of the motor leads (brush "shunt" wire) by overloading it.
Each of these motors sees as much as 1000 amps at over 200 volts. They are rated at 23 HP continuous, and we are humping about 175 HP into them for a few seconds.
This looks spectacular, particularly at night, but it is kind of like burning a piston in regular drag racing. It isn't something you would do on purpose, but it is relatively routine.
