i play alot of rally and racing games and noticed on alot of them, fire shoots from the exhaust pipes and a kid at my school has a heavily modded rx7 that shoots fire. how does this happen? is it a combination of a powerful turbo and a very free flowing exhaust? its only when shifting. i also noticed a little visible smoke comes out of cars when they shift. is that related?
what makes fire shoot out exhaust?

Running rich, or u can wire a spark plug in the exhaust.
spark plug in exhaust
this is really how they do it they wire a sparkplug in the exhaust, i personally have never heard of the running rich thing i always thought they used a spark plug. not discounting the rich stuff cuz personally i dont know, but i know ya can wire a sparkplug in the ehaust and it'll shoot a flame there is this guy at the track that is known for his supra shooting a ten foot flame out the back
he has more than one sparkplug wired in his exhaust. There is a downfall to this, backfire. if your car backfires with this is could potentially cause you to blow sometehing up. ive seen this happen to at the track.
just be careful.
nothign would be worse than backing leave your drivway and looking in the rear view seeing ur house burn down cuz the flame scorched ur garage door and started a fire

hmm, the rx7 dude definitely didnt have plugs in his exhaust...he scrapped the stock TT and put a massive turbo psuhing 30+psi of boost and $30000 (thirty thousand) in other stuff in it, he stole it from his dads bank account and he didnt even notice
Actually, some people have the sparkplugs in the exhaust, but the rally cars have those flames shooting out because of the ANTI-LAG system they have.
Basically, the anti-lag is a system programmed in the Engine management injecting an amount of fuel + lighting the sparkplug (plus other timing related adjustments) when the driver is releasing the gas pedal to shift. It is timed to ignite the fuel in the exhaust manifold right before the turbo. Even if the engine is not producing exhaust flow, the turbo is kept spooling by the explosion of the extra fuel in the manifold. The results of the explosion are channelled through the exhaust system creating that wonderfull flame.
This setup is extremely bad for exhaust wheels and turbo housings, but for the elimination of Lag during a Rally, it's well worth it!

RX-7s do it easily because of these factors:
1. They run rich because of the necessity to do so--they consume oil regularly to lubricate the seals around the rotors
2. Rotaries run very hot, so it's not uncommon to have the hott exhaust components ignite the fuel-rich exhaust.
gotta love it--no spark plugs in the tail pipes necessary...

yes mam... totally correct. Just about all of the 7's in our group can shoot some flames out the back... The largest coming for a stock port 13b 1st gen with a huge carb on it. We're talking about 2 feet of flames for a good 5seconds or so on a downshift..
The higher power cars mostly just shoot quick pops.. Stock, modded, turbo, N/A, doesn't matter... everyone gets flames
Mine shoots a little quick bright blue flame out each exhaust pipe.

My 13B streetport in the '82 GSL I used to own would belch some wild flames out of the exhaust. I also had a Holly carb and manifold from Mazdatrix in CA.
My '91 would just give the nice BOOM inbetween shifts out of the Apexi dual N1's

rotaries are so kool...good deal, rx7gslse and Mazdadan.
now the three rotor--shoot wild flames and is louder than a sawed-off double barrel shot gun at 5 paces! I love that car...

so any chance of this happening on a protege w/o spark plugs?
