Flame From Exhaust???

[TBITB]

About a year ago, while driving on the PA turnpike one night, an sti blew by me. nothin special about that, except when he droppd a gear, a blue flame spit from his exhaust! i chase him for about 20 miles. he probably knew why i was chasing him cuz he let me stay close and kept dropping gears. is this a special exhaust? can you only get that flame shot with a turbo? i dont know anyone with a turbo so i've never personally asked anyone.

one of my freinds recenty got a 07 STI i saw the blue flame too, but i don't know if everything is stock on the car. love the way they sound though.

I'm pretty sure you can only get that with a Turbo, my cousin had an Evo VIIII, and his shot the flame.

Its possible to do that to almost anycar, it has something to do with tuning your cars engine. I 4got wat parts but its possible. Some of my friends Did it 2 there car and they got lik a honda accord, civic, celica. But if u do it its goin 2 **** up your engine the way they did it. U could also do it by fully tuning your engine but that's lik with nothin stock I think

[TBITB]

yea this car definitely wasnt stock it was fast as hell. if i did it i wanna do it the right way (no rice here! and no $$$ to fix it if it messes up my car!). thanks!

i get a lil flame .. not blue tho .. its bcuz of my header tho
my brother drove my tC wen i just put the header on and i heard a nice lil pop and saw a lil flame

It is from an overly rich mixture with advanced timing. Happens mainly with turbo setups on open exhausts.

my friend has an 07 cobalt ss s/c, and he has a 3" catless downpipe and an ark exhaust, and his spits flames every time he shifts at a high rpm. i would think it was the deletion of the cat on his car, but im not sure.

[ac3 b00gi3]

i heard pops coming from an 01-02 maxima each time he shifted
dunno if flames were coming out tho
it wasn't turbo'd either

[hotrice]

yeah bud what it is is basically no cats. my best friend has an 07 sti and he has a full turbo back exuast with no cats and when he drops it a gear we get a little flame thrower. hell when i went out to the track one time i saw an evo shooting out like a foot of flame when he would down shift but like navy said its just the over riched air meeting the oxygen at a combustible temp. not to get to technical.

now i spit flames .. switchin from second to third .. and third to forth

I drove a Scooby for about 4 years.

It's not that hard with any WRX, STi or not.

Two requirements to make this happen:

1. Catless Turbo-back Exhaust system.

2. Run Rich.

To accomplish point 2, most subie owners just put on a fully 100% atmospheric venting BOV on the TMIC. The normal 1g Bypass valve recirculates all the excess compressed air, by venting the air atmospherically, you're removing recirculating air to the intake manifold, causing you to run rich. Some of the fuel doesn't get fully burnt out, and burns post Waste-gate from the turbo back.

I was hugely involved with the SoCal Evo club, and while working with them, many LanEvo's and Scoobies ran Piggy-back, or Standalone systems with Anti-Lag maps. Which reduced lag and improved turbo response, but also produced profusive flames. Also known as a "Mis-Firing System" in Japan, made popular by that blasted Anime, "Initial D"

Not hard on a Scooby or LanEvo, generally, people do it for show.

But I imagine it's not hard with an aftermarket turbo kit.

[ac3 b00gi3]

nope .. not hard at all
i hear pops w/o even trying

YAY! Very COOL! that's the only thing keeping me interested in a turbo ! i know that's not a good reason to have a turbo, but im so into the looks!

[ac3 b00gi3]

dont forget the power
but it sounds really cool
i almost spit fire wen a cop was behind me
he switched lanes right wen i switched to fourth
i dunno if he would've pulled me over or wat .. im sooo lucky

[hotrice]

i don't know if he could pull you over sure couldn't prove it in court.

[TBITB]

forgot about that part. u probably would get pulled over for that. i'll ask my "uncle" the dep chief of a.c.p.d. my fiancee wants to be a cop in a.c. so that may help me. the perks would be great!

If it boils down to testimony, it's a Policer Officer's words against a suspected street racer's word.

Chances of success, not too great.
