flames out the exhaust

JASonic · May 14th, 2007, 07:20 PM

So Ive seen in some of these stupid movies scenes where the car will suddenly start "throwing flames" out the back end. I always thought it was just special effects stuff to make things more exciting.

Ive been told that an increase in exhaust and header temperatures can help with power on a normaly aspirated engine. From what I understand, it helps the exhaust air move out of the engine faster.

What Im Asking is, is the flame thing real? Is there some system that burns something in the ends of the exhaust that creates a better flow out of the engine?

HMUSN · May 14th, 2007, 07:21 PM

yes it's real.

yes it's illegal

it's just a spark plug drilled into the exhaust and some wires.

JASonic · May 14th, 2007, 07:40 PM

a spark plug? Does it ignite the exhuast gas? It sounds crazy! There's something flammable coming out the exhaust?

HMUSN · May 14th, 2007, 07:43 PM

yea thats pretty much what it does.

your exhaust always has a little unburnt fuel in it.

i'll see if i can find a link

edit:

Here ya go

Cool. By the way, I like your sig. I love that random funny shit. Thats the guy from "300" isnt it? They look like terrorists doing aerobics er something... thats too funny!

Anyway, if its just a spark plug, thats a pretty cheap thing to do. Does it add to your horsepower with any notice?

yeah gas fumes are some of the most volital(sp?) part of gas, but it does nothing for performance. and it will burn up your exhaust

Rotaries don't need no spark plug in the exhaust to shoot some nice fireballs

Just for an example. What really happens is that at a high rpm when you let off the throttle the vacuum is high and ignition is cut leaving all this left over fuel which goes right of the exhaust. And since rotaries don't have valves or anything to get in the way all that fuel hits the hot exhaust.

Onemanzu · May 14th, 2007, 09:46 PM

AUTOloc.com... or what ever they make kits for single and dual exhaust set ups... what it does is kills the spark to the engine so more fuel can acctually get to the tips... of course this is horrible on the cats and mufflers... but yea the pretty much all it is... with a spark plug out the back

02ponypackage · May 14th, 2007, 09:53 PM

Turbo cars also can have nice backfire like my buddies Silvia...its nice seeing a ball of flames come out...nothing like my buddies cobra wen he missed a gear and flames out the pipes lol...but the FandF sitting at a lite...is a little kit for it or DIY illegal indeed...a guy in orlando has a V6 that shoots 6 foot flames lol...he was also featured in Muscle Mustang b4...

Onemanzu · May 14th, 2007, 09:56 PM

yea i saw that feature... first copy of MM&FF i got

he also had a super charger and was puttin down like 290 sumtin

02ponypackage · May 14th, 2007, 10:00 PM

yeah thats him....he has the SVO scoop its a two tone car silver black....

punkafi888 · May 15th, 2007, 12:53 AM

no no no, you push raw fuel through your engine and the spark ignights it. bad idea you end up with fuel in your oil. but you can hook up a little propain torch. and thats not a joke.

I thought you could shoot flames by running rich too

Onemanzu · May 16th, 2007, 01:03 PM

if you rev it way up high and then drop it really quick you might have a chance
