I know that some of the high powered Cosworths run 4 injectors and i know some run 8, but what is the advantage, if any, of running an extra set of injectors???????

Or is it just a case of "Pub Talk"

Ryan

i would say 4

good managment and 4 would be the route i would choose


less injections is less that can go wrong,


would you know is 1 of the 8injectors had failed????

i know you DEFINETLY know if 1 of 4 did


i await my slating on that

No

Better atomisation from the second set although the horizontally mounted inlet does cause excessive fuel drop out.... but still better IMO.

Overall though given the extra hardware, the wayit fires and the aggro and expense to get it working, id opt for 4 injectors everytime.

TIFF

What do you accually need for both set-ups then, say for instance you want 550bhp,and what sort of costs?

i gotta say it im an 8 injector man

surely more chance of failure. If one of the second injector fails it will run lean as one of the two will still be firing and kill engine. If one of the injectors in a 4 setup fails it will just drop onto 3.

good question ? but i would leave it for the engine mappers to answer

i suppose it has may be alot to do with what management system there are useing

I pectal T6 can do both and controll 4 or 8 just as good as each other

Nothing to be ashamed or embaresed about Gareth, there are a good few of us "old school" 8 injector boys on here

My Dad went for a modded plenum elbow and 4 x 750cc injectors on a Level 8...cost the replacement injectors and about £60 for the plenum and mods....

And Marco...PECTEL is spelt PECTEL!!

My ECU will handle either. Used to have 4 x 750cc's now using 8 x 575cc's with my new engine spec.

Technicly 8 is better if the 4 are downstream, but would you REALLY feel the difference? hmm doubtful.

And for the small (i expect/understand) advantage of 8, id rather run 4 for the far simpler set up, and less chance of catestrophic failiaure...

Fagin

Sorry....

Bigger is Better!!!

EIGHT all the way baby!

TIFF

Is that why you are some 7ft tall mutha fucker

neilm

I just knew all that gay talk about Stage 1's wouldnt last....


Tiff by far the best way to go is 8 injectors.... it means you can poodle round the town etc and its like you've got a sensible stage III car, nice and economical on long runs etc...

But.... when you need the power... its there !

Anyway... why are you asking us ?

Just ask Karl....

DaveEscos

yes, why not ask karl

oops sorry, forgot to add the next to Karl

Same goes for 1600cc injectors if their mapped correctly Neil so thats no advantage at all. (And from the maps ive seen, its bollox anyway )

TIFF

I am not asking with the intension of doing it, i was just curious

I have just gone satge 4 and i am chuffed to bits with it

Stu...surely a fuck off big injector x 4 squirting on a long run will overall be worse on fuel than a small injector x 8 As when you go to overtake your put the foot down and be using more fuel than the 4 of 8 scenario?

He is at the Nurburgring Dave, otherwise i would of asked him over Tea

Sorry Stu... I'm living in the past mate...

No shit sherlock.......


I knew the Stage 1 wouldnt last...... it never does

No mate as if we require 14:1 and use an injector twice the size we simply halve its on time.

Lee Reynolds

But on a 4 set up, surely if its on three the cylinder with the fooked injector could run so lean say on full chat the fooker will melt? Or is my lack of tuning knowledge showing thru?

TIFF

I was TOTALLY happy with the Stage 1 but i just wanted some Pub Talk ammo. T34,Greys etc

Ima-Racing500

Stu...i take it this is a bugger to acheive on L6/L8.....i say go 8..looks the bollocks aswell

Lee Reynolds

Just copying POPS. Only HE is about 34 and grey

RAFLMFAO

Now Lee, that is a fucking line

L8 is a peice of piss to get lambda 1 with!

My Dad's car is more fuel ecconomical on 750cc injectors than greys.....

jas

dont you need 8 as with high flow injectors the time they need to be on at low load ect would be minut so have 8 medium size ones so then use 4 at low fuel requirement giving good atomioizTION ETC AND GET ALL 8 GOING WHEN MORE FUEL IS NEEDE.
aLSO I SEEM TO REMEBER THERE IS AN ADVANTAGE OF having the injector further away from the valve for high engine speed performance

Stu @ M Developments

No mate, its quite simple.
Put it this way, i wouldnt charge anymore to map 750cc than i would greys mate
