Fuel + air + spark = fire.

i've seen them plumb a line into the exhaust from a small propane bottle and have a sparkplug behind it. then in the cab you push a button to release the propane and ignite it with the sparkplug.

Bee-R rev limiter/Gizzmo launch controller will do it.

tl;dr unburnt gas igniting in your exhaust.

Build a high c/R motor with some major overlap and make it run rich on deccel, or throw a carb on it and make it a little rich at idle.
