Shooting flames is pretty much impossible with a cat so if you still have a cat I call major BS

 

no its not, if its running super rich, all you need is a backfire to lite that **** built up in the cat. Ive seen it on several chrysler products ive worked on.

 

not completely imposible, it's been done on my car and a few others I've seen. Just makes it a little more difficult.

 

Really? Like I have seen it but it was on really old cars, never on anything new.

I thought it was impossible so I guess I will be quiet.

 

i wouldnt call BS. It could be done.

 

it was easier on older cars because all the gas would accumulate in the muffler, and being so hot, could flash ignite. The honeycomb design in the cat helps keep the gas spread over a greater area to help lower the possibilites of flamin' exhaust.

 

True story, seen it personally, and scared the **** outta me..caauussee, i was unaware that was about to happen

 

I got this same issue on my vtr1000 superhawk 996 when it runs to rich. All the friends think it is great but it just means it is time for a good tuneup and resinking of the carbs. I would say get someone to do a tune on it.

 

Ha my first post is a hit, iv been watching this fourm 4 a while now N never saw a post which N turn thought it was not normal, glad 2 see other tc's are poping out some fire now the trick will be to learn to do it on demand N get a nice pic to post 4 you guys

 

If someone does take a picture, please make sure you have a DSLR or it'll just be like poo.

 

P.S Stock tune Catted d/p still shootin flames it is possible, is it a good thing? prob not thats why gm gave it a 5yr 100k

 

anybody got a video of their car shooting flames?

 

No lift to shift is done differently on each car, some cut timing or fuel, i know that the ss/tc also changes cam timing during a shift. If it makes it pop a flame out back who cares, its a factory feature.

 

Haha must look sick when it dose spit flames..

 

Yeah, you're just running stupid rich. Get a tune to lean it out and it will stop I guarantee.

 

TUNING WILL NOT STOP THIS. Do people really not know how the no lift shift works? If it was a ss/sc that was shooting flames, then it needs a tune. I can bet that cars with the wot box also shoot flames. its caused from what the computer does to make the no lift shift possible. YOUR CAR IS FINE!

 

I have to disagree, you get it lean enough and there's no way you're going to be shooting flames, no lift shift or not.

There just simply won't be enough unburnt fuel left after a tune to ignite, especially after a cat.

I mean, that's my opinion, I could be wrong but I've never heard of stock cars shooting flames unless it was running rich as hell.

 

here's a few, bad runs since the car wouldn't go into 3rd

Have you done any runs on DR's? Sounds like you got major issues hooking up, 400 hp tends to do that though.

 

Fast and the furious yo!! People will think you have Nawzz!!

 

In order for a flame to make it all the way to the tailpipe, there has to be sufficient fuel to allow the flame to make it all the to the tailpipe. Enough fuel to make it to the tailpipe is way to much. Chances are you're not no lift shifting fast enough.

Now throw on top of it the fact that he has a cat. Enough fuel to get past the cat and still have a flame at the tailpipe is stupidly rich.

I know how no lift shifting works. I'm not new to the game. Every PROPERLY tuned car I've seen with no lift shift, does not and will not shoot a fireball.

kthxbye

 

I run on dr's, last few times out at the track were just testing days to get the suspension right and relearn how to drive the car. I was really babying it out of the hole and not going WOT til 3rd gear (trying to keep my tranny in one piece lol) next time out though I'm shooting for 11's.

do you even know how no lift shift operates? it cuts spark, you're still getting fuel. If you don't shift fast enough you will get the fireball no matter what hell my car does it at the end of a pull (I do have it richen up up top though to bring cyl temps down)

 

Almost every time i shift DOWN to 2nd my car sounds like a cannon...All i have is a magnaflow muffler.

Sounds cool i guess but like the OP said not sure if its right...

 

ya i have that but its not a problem! im running full straight pipe exhaust, no test pipes, cats, not anything, if you have all that stuff and still does it, then...fix it

 

it means your car has come out of the closet! jk bud. its prob your tune
