detroits making fire

it seems like most of the ones I see that have the fuel cranked up do that. I don't really know much about them though so who knows what else goes into making them do that.
 
When more fuel is going into the cylinder than can be burned cleanly:some goes out the exhaust and is ignited by hot exhaust components. All old mechanical diesels can do that
 
It is a 2 stroke engine meaning it does not have an exhaust stroke of the piston to push exhaust out. It has an engine turned blower to push the air through for intake and at the same time pushing out the hot exhaust. There's going to fire when you design an engine like that. All the mods just add to it.
 
The 2-stroke detroits came out with a direct drive blower. (that is where the old street rods got their term for the blowers used on their engines. a "471 jimmy blower; for example; originally was on a 4-71 Detroit. Detroits were also known as GMC diesels; hence the "jimmy" term.) In the late 70s; I heard of some folks using a turbo on the 6-71 Detroit. original advertised hp was 238; claimed hp with a turbo added; 292. still would not run with the "shiney 290" Cummins. In the detriots; first number is number of cylinders; last is cubic inches per cyl.. Some semi trucks had 12 v 71. (v 12 engine)

The "blower" on a Detroit is not a super charger....its a exhaust extractor. It just blows the exhaust out then the clean air is scavenged for the next power stroke. They are all classified as naturally aspirated until a turbocharger is added or factory installed. :D
