i saw a 240sx hatch (s12?) racing a lude the other day, and i noticed that when the 240 shifted, he had sparks come out of his exhaust (dont know if it was sparks, a flame or what). what causes this to happen?

 

pretty tight huh. my lude does that.

 

lol

thats due to being rich

unburned gas in the exhaust system ignites

and wha-la : 2fast 2 furious all over again....lol

 

go get a "Fireballz" muffler from ebay.... haha.... jk

most of the time your seeing flame, due to no cat or a gutted cat, its unburnt fuel which can ignite in your exhaust.

dont want to do it, just wondering why it does that.

 

i had that when my O2 sensor was bad i was running rich, and it did that everytime i switched gears at high RPM's, i was cool

 

in japan, wasabe causes flames to shoot ot the exhaust. here in the us, mexican food combined with hot sauce usually does the trick.

 

lol. my cat is gutted

 

ya see flames comin out of the mufflers for boosted supras a lot, cause the ecu sees all this air coming at it but the BOV lets it out when they shift, so the mixture becomes rich and the exhaust ignites out the muffler

 

my lude does it randomly too, its pretty sweet lookin... dont know if its a good thing though

 

fast'n'furious stylz man....

 

lol I have a 240sx that shoots flame. It sucks because it uses alot of gas. Too bad I am hoping its gone tomorrow since I have a extra O2 sensor on my header causing it to do that. Tomorrow its getting welded and a new muffler.

 

I never understood why people think that's "cool" or "tite"...

 

mine did it untill I got a twin loop muffler, guess it just isnt making it all the way out now

lol I dunno- i think it looks sweet on the supras at the dragstrip. I guess boys like fire. I mean imagine driving down the road and seeing fire coming out of the exhaust of the car in front of you- thats frickin scary

umm because it shoots fire ***** out the muffler. dont get jelous. lol j/k

 

means ur running rich...tune ur **** noob

 

most of the time the Supras do it is when they are untuned or have a 2-step or anti-lag system...either way ur car shouldnt do it on a normal basis, its not good for normal driving. But there are those ricers that think its hella fast and furious yo. w/e

Yeah, driving around while running that rich IS scary.

You want flames out the exhaust?

i dont give a **** about if you guys scorn fire out the exhaust.

whenever i see fire out the exhaust of an f1, grand prix, or highly built race car, my heart skips a beat.

unless it was intentional, such as the fast and furious, which would be entirely madly homo.

 

^^ ouch lol. i've had the same problem before... i replaced the cat w/a testpipe and couldnt get the o2 sensor out of the old cat 4 a few days and drove w/o it. def. made it run a lil rich lol
