Some friends and I were on the mountain doing some spirited driving today and a friend who was behind me swears that he saw my car blow a small flame out of the exhaust? He said it was seen several times as I would be entering a turn and downshifting or when shifting after carrying high RPMs through turns?

He's always kidding and joking around for days at a time before coming clean.

Is this possible? How and why? I have seen this with turbo cars but never a NA car......

 

do you have a cat?

 

Hey Josh whats up bro? I'm running stock cat. Could an aftermarket cat cause this though?

Anyone with any ideas as to why if true?

 

Ahhh I guess its Zzzzz time for most. Im off tomorrow so im up late. I will follow up on this in the morning sometime and see what I have then.... TIA guys...

 

RICH, and it's not very uncommon. It's not gonna belch out 12 inch flames like a 1000hp Supra or anything. But I've seen plenty ITR's and hybrids do it. I was told my R did it with a test pipe and 5 Zigen fireball cat-back.

 

I've been told my car has done that occasionally on track. Stock motor running rich with no cat.

well i have 2.5 all the way back and no cat... the thing sure sounds like it back fires at least once a day on the interstate when i decelerate.... pretty funny actually

 

yeah the set up i'm running spitts out prety good size fireballs i guess heh, about the size of a coke can from what my buddy says.

sitting with like 232whp/JUN Header, 2.5" from the header all the way back to a JUN MM muffler. no cat, no resignators, and the piping is mandrel bent

i can definately "hear" the sounds of fireballs when they happen, i just hope i don't set my rear bumper on fire

 

Where's that pic of Robs car when I need it....

 

You have to remember it is a high comp. motor reving over 8. There is lots of backpressure.

 

it's kind of funny, i'll be stopped at a stop light and what not and have all sorts of people pull up to me and give me even elderly people

I think I faintly remember that pic.... Maybe I dont I dunno. However I would like to see it.

 

I always see lots of subaru guys doing it a lot!

WRX with catless turboback + WOT and speed shifting = spittin mad fiya

 

Brings new meaning to the term, "fart can exhaust"...

 

Get yourself a nice dragon sticker and when people make fun of you get them to stand behind the car

But yeah that's unburned fuel combusting somewhere along your exhaust, enjoy it!

 

My car is still running real rich, and I swear it does that same thing every so often. I wish I could get some pics of that!

you mean this?



always loved this picture.....still do.

 

one of my friends car does this like crazy and can do on command, but it is a fd rx7 turbo II with a racingbeat turbo back.

that sounds sounds like purrrrrrrr sexxxxx

 

i heard it does that when the back pressre and opposing pressure meets. or something like that..

Full Throttle and let the gas go. then kaboom. only if you have a good flowing. non restrictive exh system.

Your friend either has a FD RX7 or a FC RX7 Turbo II. There is no such thing as a "FD RX7 Turbo II".

 

I do it all the time in my EP with IPS cams, 4-2-1 race header (cat eliminated), and HKS hi power exhaust. Its makes a very loud pop sound too. It only happens in 1st gear where I'm pig rich and when I'm on/off the throttle under 20 mph... its neat and all but I'm sure it will go away once I get my kpro/k20a2 tuned.

 

my h22 accord shoots flames if i shift early at full throttle in vtec.

 

hell, I shoot flames all the time..No cat..check my avatar..

 

it's hard to shoot flames if you have a cat, but wiht no cat, flames are very possible on an NA car
