Injectors 1000cc brands

[Luchitosan]

Hi guys, i was reading a lot from the forum about the injectors so my doubt is

Whats 1000cc injectors works better for the ca18 engine Delphi or Deatschwerks ?

The two can can work w/ alcohol if i whant to ?

Most ppl here knows well the deatschwerks any experience about the delphi ?

Please coment, thanks you !

Either will work just fine.

Take a look at injector dynamics. I've heard great thing about them.

Thanks, but don't what add any other brand

I figured that, just think maybe some be most compatible than other o some s*** like that

I'm running Detchwerks 1200cc injectors on E85 and have no issues. Idle is great and fuel economy is pretty good considering it's on E85. I'm running 50psi of base fuel pressure.

Damn

[float_6969]

That's the pressure the injectors were tested/rated at (well actually it was 45psi IIRC). If I ran less, I wouldn't have had as much fuel flow. I didn't talk to Detchwerks, but I was also concerned about what would happen to the spray pattern at a lower fuel pressure either, so I adjusted my system to match what the injectors were rated at.

If my math is right, my Walbro HP should max out about the same time the injectors do, but I don't think I'll get anywhere near that with this turbo. I could be wrong though. E85 can be funny like that.

The engine is just rebuild so need run a few miles/km in stock way to check any issue, etc.
I'm gonna update some pics soon in my build tread, but next step will be nistune board, fmic, and this size of injectors.

I don´t know anything about the tune injection but i guess when the time comes, I put these bigger injectors
with standard pressure (36 psi), the injector pulse width need be less to equal the 370cc oem i'm right ?

[float_6969]

I'm not sure what you're asking, but I think there is an easy way to change injector size in nistune.

Well, it would depend on what fuel pressure the new (1000cc) injectors were rated at, but yes the pulse width would most certainly need to be less to net you the same amount of fuel as with the stock injectors.

Yes there's a simple way to change that in the nistune but nothing describe about the fuel pressure,
at least in the notes i' ve but, I guess from 40 psi might work

[float_6969]

If you have an adjustable fuel pressure regulator, you need to set the base fuel pressure to whatever the fuel pressure the injectors were rated at. If you don't have one, then you need to contact the injector manufacturer and find out what the fuel flow is at the pressure your regulator is set at. Then use that flow amount to change the injector size in Nistune.

You need to use the wideband air fuel ratio meter to tune the K Value and injector dead time.
The result of the "simple way" is accurate ONLY IF the injector dead time is the same as stock injectors.
but usually hi flow injectors had higher dead time, so, the K Value must have to tune for best result.

Agree !

Ok, first need find out info and yes have a FPR.

Thanks you !

Yes, that's what i read in the notes, and with the manufacturer fuel flow data gonna' help to do that.

Thanks you !
