600-700cc Injector

[T04GTR]

hey all, im trying to find the best spraying injector around the 6-700cc/min range?

must be a single cone.

high or low impedance

siemans deka? rochester? bosch ev14 ???

any first hand experiance?

cheeres.

Injector Dynamics...they certainly have me impressed. They make a 750cc item that would suit you nicely...we recently put some 1000's in a stock GTR and the fuel delivery was spot on...afr's were rock solid at idle even with varying inlet temps.

have a good read of their website Dave and let us know what you think.

Dito , everyone falls in love with those ID EV14 injectors .

A .

[T04GTR]

so they are a customised bosch unit yes?

[discopotato03]

I don't know exactly know what ID do to them but from what I read they are a late model higher plessure injector intended for returnless EFI systems .

The moving part inside the injector is much smaller and lighter than older types so easier to control at small and large pulse widths .

ID are supposed to got to a lot of trouble to match sets to ensure uniformity .

Google Injector Dynamic and search here under EV14 Injectors .

Cheers A .

Paul Yaw is a smart cookie. Been reading his info for ten years odd! Im going to be running the big ones ! .

I think it had the relevant links .

are these the high impedance 1000cc ? would they work with a rb25 power fc without a resistor? what psi are they rated at 1000cc

edit found this chart

The nismo 600cc about the best I have seen.

[T04GTR]

cool. but when i can get brand new deka 4's for 40usd each its hard not to take notice. not a fan of "customised" injectors. i just dont know if there is better. spray pattern wise.

ps. does anyone know where i can find technical product sheets for these said deka 4 injectors? (60lb/hr) long series.

[Walk510]

there not as such "customised" more matched so you shouldn't have to trim individual cylinders more that a couple of % there also batched so if you have an injector fail you can order another injector of the same batch

also they have a youtube vid of running id2000's in a NA integra there said to idle well

the twin turbo V8 boy are using them too as you can run big pressure to the injectors the 2000cc can run to 3710cc with 130psi to them

i believe they match them by the duty cycles

7000revs 80%

60%

40%

20%

6000revs 80%

60%

40%

and so on

and different voltages

But why so expensive! Oh well, one day my thing will get to drink some E85

[T04GTR]

exacly. im running a 12 injector setup. (2 per port shooting at each valve) rather than bashing anywhere all over the port wall.(ie stock)

havent decided whether to have them staged or running in parralell.

i got the idea from nissans new system

also some sucessful race engines ie: s2 quattro pikes peak

[discopotato03]

ID don't say which EV14 their injectors are based on , could possibly be some of the Bosch Motorsport versions ?

A .

BTW the technology used in those Quatro Sports and RS500 Sierras is not cutting edge these days .

[T04GTR]

funny. still used in the pre diesel r8 lemans cars... meaning the inlet manifold design and 2 injectors per port.. (before fsi injection)

most of the f1 turbos and most of the current wrc inline 4 rally cars. cosworth,scoda etc etc.

[T04GTR]

r8 lemans fsi

quattro

wrc

[T04GTR]

yes im doing the same design for my rb26

[Walk510]

one question will the ID injectors help your car win races like vipec does ? or will it have a good idle ?

and happy new year !!!

[T04GTR]

yeah for sure. in my pants!! happy new year too.
