850cc - Too big

[europeanme]

finally ordering my injectors and just for my piece of mind my dilemma...

850cc - too big
550 - too small
750 - just right

or just go out for 1000 to future proof any more upgrades....

i think you should go with the 750 ones!

what's the setup?

PS: i think the problem is you are buing too big brakes.

[Rocco]

how many Hp are you thinking to use my mad friend?

think that if you use one day E85 or similar fuels you would need more headroom injectors

Does not matter with EV14's.
Even 1000cc's idle just fine. No such thing as "too big" until you get way over 1000cc.

[Jamo]

why are 550cc to small? remember injectors are rated at 3 bar normally and with the S2 aby running at 4 bar so a 550cc injector should flow around 635cc

You want the smallest injectors possible to reach your bhp limit, makes idle control easier for a start

To some mappers it makes no odds, there is a famous incident with Ross's car and a certain mapper who couldn't map his car because 630cc injectors were too big :corey:

If you want to future proof just use 750cc, you'll have a hell of time maxxing them out unless we get e85 uk wide which will be never as all petrol courts are oil company owned here

[Rocco]

550cc injectors with 4bar FPR = 550Hp possible with ron 98 fuel

if they are too small .... you will build a killer car¡¡'

[caterpillar]

will the org motronic ecu take them or do you have aftermarked ecu???
max 80% duty at the injectors... so 1000ccm /96lbs will be nice...

[prj]

Tested motronic fine upto 750cc, I don't think 1000cc will be a problem.

slightly off topic, tonight it had it's first kill......s2 1 peasant 0 not proud as the little thing could have done some damage...and we will tell tomorrow morning....
stupid bird straight under my back wheel....and thats right under the exhaust!!!....it'll teach me to not go around on WOT!...

back on topic...
it would seem that my idea of 750's is a popular choice...

@Caterpillar, hopefully motronic...

@Vas, you could be right....i love big brake set ups...t'is a shame i couldn't deal with having 19"'s on the car else it would have been Rocco's...and the set up is still changing as i go....

@Jamo, 550's are at the bottom of the scale so I assumed that bigger is better (up to a point at least)

thanks for your input guys...any more thoughts, as i won't be ordering these til next week, are welcome......

cheers

If they are EV14's as someone said above up to 1000 cc they more or less react the same, I have 750cc and I doubt you'll be hitting my power levels
