i'm going to ask a really stupid question here but i just wanted to ask....

why do some RST's and cossies flame but some don't at all??? (even when they are similiar spec)

AND

How come big powered but BRAND NEW cars don't do it?? e.g. the new M5 508 bhp thing....take it that wouldn't flame???!? but a 508bhp cossie would!!!




talking of flames....i am now getting prepared to be shot down because of this post

1) the map some run richer than others.

2) combination of map and also cats

stick lambda control in there somewhere too

why.. why.. why...

this is you

big_wig_074

due to mapping and better faster reacting injectors etc as far as im aware,i always loved the flames my old grey injectored saff put out!

keithG666

more worrying is......WHY WOULD YOU HAVE THAT PHOTO TO HAND?!?!?!

Stavros

whats new

Mapping

Over-run fuel cut-off for one, if an M5 did the CAT would be fucked so quick.
Also Mapping. Exhaust temps. etc etc etc etc etc
And a V10 M5 isnt that highly tuned compared to a lil cossie 4pot at same power is it...

Aaah, look i did a sensible post with no abuse


You prick

You just know thats a nut sack

its funny..

Remeber the filming with my flames I think it was you..

Anyways, to answer your question.. its to do with mapping and stuff

keithG666

its what happens when i'm totally mechanically illerate

my reaction when we took the head of the engine sums it up....

"where the fuck is that water coming from???? does that mean i have water in the sodding oil now??"

Simple, over-run fueling and exhaust temperature

unless you bouncing off the ign cut rev limiter

my cossie used to do wicked flames when doing silly speeds on the chip that was in there when i got it, but then when i got SCC to do a proper stage 3 jobbie on it the flames stoppped

Anonymous

Stage 3 cossie chips often have a massive amount of fuel on the overrun, so when you are doing 6000rpm in 4th and shut the throttle it continues to piss loads of fuel in which the engine doesnt use, combine that with a red hot exhaust and you have big flames.

My Focus flames briefly on the limmiter if the exhaust is hot enough!

I've got vids of my old VTS flaming on the limmiter/on hard banging of the throttle with just de-cat + Magnex.

Switchs Cossie....that used to piss sooooo much fuel out on the over run it was unreal!!!!!

boXXer

surely thats bad for the bores though? someone once told me that a car that is PROPERLY set up, shouldnt flame at all.

xr2i-carl

big bore wash if theres that much fuel on the overrun

Mine had good flames on the Bedford track day, seen the vid.

Also i liked it when you change gear when giving it loads and you hear a big boom out of the car.

I had that on M25 one nigth racing dave, after lifting off a held 5th flat out......absolutely shat my pants, I had only had the car 2 mt=onths thought id blown it up, I even pulled over to check everything was ok

Niall.b

RSnutter is always on the limiter

Ginge !

my old chip used to kick out 5 foot flames from the rear it i changed gear quick enough ( cant think why i need a new box ) when i got a chip of stu it aint as bad and only about 3 foot

well untill i got the ignition problem and then it started flaming so much at times i could see em in the rear view and would light up country lanes

back on topic,,,,,,,,,,,,,, novas should never flame UNLESS ya the repair bill is biger than the insurance payout

It only happens if you blip the throttle at around 5K ish or change gear just before the limiter - pops out a bluey yellowy flame most times and sometimes real sharp crack as well.

Or is this a piss take?

I am but an impressionable young lad after all

I could get flames out my MK2 rs2000 with the pinto in....

All depends on HOW much abuse you give it....

Manifiold temps and single box - they were little blue ones out the back of that...

Mine will flame easily with or with out the flamer LOL..

Anonymous

that sounds different to "pretty mad flames" like you originally stated

Max

and his flames were massive but that was with a flamer kit

I wish mine would stop with the flames. It's killed my bumper

Yep the word HAND springs to mind eew!

Well they are sometimes about the size of a football if that makes sense? I just didn't think a basically standard car would do that.

DanRSturbo

I had a couple of little blue one's when it was over fuelling

CarlRsT

Mine spits a few out every now and then, pops alot to when I let off the throttle
