.......Missfire and generally throw fire out the back of the car when you put you foot down and there isn;t a great deal of petrol in them?

mines a fooking nightmare if i have less than 1/4 of a tank.

 

nope - i think your car has issues mate.

have you checked fueling?

 

If the swirl pot inside the tank isn't a very good one, under sustained hard acceleration they can do this when low enough, mine was same with old tank, over 1/4 no problem, also did it on extended high speed cornering.

Sounds very similar to mine, nothign to worry about then hopefully

 

Mine does'nt.........

 

mine never used too, only seems to be now with the extra power, what kinda bhp's yours mike?

 

224bhp,

Its a virgin

never been touched...

 

Thats probably why then, the extra G's are probably chucking the fuel backwards a bit harder, plus the injecters need a lod of fuel, hmmmm!
Would an extra fuel swirl pot help, can you get them?

 

Yes you can buy alloy external ones.

 

Might be worth an investment at some point, of maybe i should just keep it about 1/4 of a tank. lol

 

I think that you should check the fuel tank as tabetha said because mine never do it even if I drive with the fuel warning light on no matter what cornering speed (400 bhp and 044 bosch pump). Maybe the pipe that goes to the swirl pot inside the tank has got a hole or something...

 

I'd sort it sooner or later. You could melt something if it keeps doing it.

 

i dont know what there is to sort?!
and my main trouble is i absolutely hate doing anything on my car, it always goes wrong.

 

Mine did the same the other day, but that was going around a corner quick and at the bottom of the red. The same sort of spec as yours aswell. Its never done anything like that before, but then again i havent run it to the red before.

 

You have a fuel supply issue of some sort, as in you aren't getting enough. Something i'd take very seriously! Its either you pump of the swirl pot system in the tank.

 

It sdefo getting enough juice, it was only at MSD a a month ago and was perfect then!?

 

I've noticed mine now chokes a little on hard left corners, particularly with a relatively empty tank - guess this might be down to my pattern tank having no swirl pot. Wish I'd pulled the pot out of my old tank before it got binned

 

my mate has had a problem like this required a new fuel tank got 1 off ebay for about 35 notes

 

right, is it easy enough to see if the swirl pot is knackered then?

 

shouldnt do that mate ive got 470 bhp with 044 pump, pin it when fuel light just comes on and it doesnt do that. on my 5th cossie now and none have done it tbh.

 

Pattern tanks can be terrible in this respect, the oe fuel tanks supplied on the cars had excellent swirl pots that were filled by the return line, before excess fuel over and above what the swirl pot held simply got pushed upwards and over the top into the main tank, these swirl pots were made by Mercedes!!, but worked ace, plastic in design, exceptionally unlikely to be a in tank prob with these as the pipes are all solid, right from tank outside to tank inside into the swirl pot.

mine doesnt do it either. I sometimes hate working on my cossie too cause you end up fixing something and then something else goes wrong.

 

That's Cossie ownership for you!

 

If you hate working on your Cossie cos things go wrong, SIMPLY IGNORE the fuelling issue!

Then ENJOY fully rebuilding your engine cos a piston melted like I did.

 

If you hate working on your cossie either be rich(and pay someone else), or get another car!!

Did they check the fuelling when the missfire happened though?

 

yep!! mine did that a huge missfire when tank was near empty, sometimes would even fail to start until a gallon of fuel was put in & then all was fine. Never did get to the bottom of it, just kept tank 1/4 full.
I think it goes without saying that their was nothing wrong with the set up of my car, fully serviced every 1500 miles & fuelling check before every Topspeed run & no probs ever found.

 

Nope, it had over half a tank when it was there.
I worded myself a bit wrong above, i dont mean i hate working on it, it just worries me if i break stuff or cant put it back together!

Been out in it again now, with the same amount of juice and its been grand again?!
odd car.

 

Mine does it half way in the red but only every now and then
