I think they do if they run rich on over run?

NEEDFORSPEED

me too

I know scoobs do it more commonly but thought it was cos they had different engine,management etc.

Fudgey

most early chips were copies of Group A rally cars, so yes, they squirt in extra fuel on over run to cool the pistons and valves etc, and of course this then gets ignited by the bloody hot turbo exhaust housing

dave cos4x4

iTrader: (5)

isn't it when the exhaust is very hot and the unburnt fuel in there is igniting.

Staffi

Mine does, OH SILLY ME, that's cus i've got antilag..


Rich i think Kev...

Daviet

as said over fueling usually and normally sounds louder when exhaust is hotter.
when andy forrect remaps his scoobies you can get a pop and bang map or a normal one

Staffi

Daviet, but is Over fueling safe??

KSA-Cossie

My car pops a wee bit now it's feckin baltic ambient temps

Daviet

does lots of it not cause bore wash? your asking the wrong person here

Staffi

iTrader: (1)

At least you're honest mate..

dave cos4x4

iTrader: (5)

it will cool the pistons down.

Spiky

ford sent them from fatory like it

rapidcossie

Constant Rich(very rich) running causes bore wash and contaminated oil...

Running a bit rich after large periods of WOT when completey backed off the throttle is something different and perfectly safe

As above, its just fuel that hasnt been used in the engine.

KSA-Cossie

iTrader: (4)

Thats cleared it up for me,ta gents.

Staffi

So, is this what cause some cossies to flame like fook on track and some not aswell.. exscuse my ignorance

rapidcossie

depends on how they are mapped staffi...

Staffi

iTrader: (1)

Euan, just that people have SO many methods about how there cars flame and what causes it..

rapidcossie

Mines used to spit flames for fun after Mark mapped but now only flames after a long period in 5th gear since Alan remapped it so it seems to be down to differnt mapping styles?


I think that a leaking exhaust used to cos some on my flames...they used to get so big that it was just crazy...

Csm

My old one used to pop and bang brilliant but it was over-fueling like fuck due to shagged chip and some cunt wound the regulator up bigtime previously, car was actually misfiring on way to ava to get set up with excess fuel

Thanks to AVA they sorted it out ,car ran brilliant and smooth and i was saving a small fortune on petrol

KSA-Cossie

Yo big fella how's the family and the business ?

Chip

iTrader: (3)

Most of the cars that flame a lot are helped out by a plug up the exhaust to make sure the fuel burns as it comes out.

also any exhaust leaks make it worse by letting in oxygen to add to the fuel and heat already there,completing the things needed for ignition

Csm

Braw Kev , were all full of flu and im still a moaning cunt so nae change there , business is doing well just now and hopefully some good amounts of work via a trader i did an X5 for on monday and scored a few regulars already, maybe even getting a full taxi fleet to valet before taxi-tests, so all in all no bad and still juggling my part time hours with my work aswell as self employment, lol aint had a day of in fookin ages and even had to turn work away this week sadly ,if that keeps up ill be handing my notice in fully at work to go full time on my own

Hows u buddy, Lookin after ma future saph

frog

So that's 10p a pop on optimax

dave cos4x4

iTrader: (5)

a foooked inlet manifold gasket also causes the car to pop and bang.

KSA-Cossie

iTrader: (4)

Thats great news then pal,youre future saph is going great,might be going for 400+ bhp soon.

Morning Dave

cossiegreg1

so if i was to ask the person who was mapping my car...."i want it to pop and bang, on over run" he wouldnt laugh at me?

mechanic28

iTrader: (5)

out of interest are all the cossie that smoke pop and bang running L6 ecus???if so i have a poss reason

foreigneRS

some of it is down to the filtering used for the inputs to the ecu of MAP etc

JTECH James

iTrader: (13)

closed loop cars have a fuel cut on over run this is to prevent cat damage.......this may stop l8 p8 cars from popping,as mine doesnt......i have a 22+afr on over run
