what makes a car shoot flame out of the exhaust ?

im not talkina bout that gay ricey spark plug ****, im talking about the sick road race cars that when they shift a flame shoots out o fthe exhaust . .


do n/a or turbo cars do that ??

 

not if they have a cat :D both n/a and F/I cars can do that, it's just a matter of excess gas in the exhaust. Some F/I cars run anti-lags that spray gas into exhasut side of the turbo to keep it spooling, this can make flames i believe.

It's just a bucnh of unburnt fuel going through the exhaust from letting off the throttle, the fuel maps on those cars still feed it like it's at wot for a few revolutions after it's released, then I'm not exactly sure why it explodes, I know our old school bus would shoot atelast 10 foot long flames out the exhaust by my house everyday cuz they would shift right there.

 

MORE MORE MORE INFO PLEASE . .

 

Well if you have worn out ignition system, wires, cap, rotor, plugs, it will not fire and then when the ehxaust open on the next working cycle theres still a gas air mixture in the runner right after the valve, Or if it runs very too lean it can not fire and catch on the exhaust stroke of hte next cycle also.

lol this make me laugh when I visualized it.

 

ok kool, any pics ?? more info

ty

 

i juss got my ls/vtec setup tuned with hondata and when i shift at 8 it shoots 2foot blue flames also, my tuner said it was because too much gas bein dumped........i really dont care because it looks tight

 

I shoot flames after engine braking because of the way my fuel is mapped and my car is setup. W/ the ITB's running fuel off of vaccum causes rich conditions in certain places and it'll shoot flames.

 

He he, If i go play with the V-AFC i can get you a pic of mine too lol.
