Hi guys
I did a search on the ford injctors and read a couple of post now heres the questions.

1. in one post it said that the ford #24 injectors are measured at a lower psi is this true?

2. If Q#1. is True then are the 19lb/prhr injectors(fords) also measured at this lower psi
if so what do they rate at GMs psi

3.in a post someone said that the #24s were to much for a modestly(minor) moded motor. Since I am sizeing up from my 305 to a 350 I will need a new PROM anyway (changeng the pulserate) will these injectors work fine once the prom is calibrated to the larger injectors

4. what kind of advantages or dissadvantages will I get from useing this setup (any little help or insight will be appreciated)

the reson that i want the fords injectors it becaues there so cheap.
I revised this after the first reaply to clear things up a bit
thanks jacob

In answer to your questions.

1. ford #24 injectors OPERATE at a different psi, I think 32 to 36 not real sure. You need a AFPR to turn down the the fuel pressure in a GM TPI system.

2. GM's #19 injectors OPERATE at 42psi just like the #22 injectors on the 350's.

3. I'm just starting to get into prom burning so I'm not to familar with the injectors but I have seen in the program a spot for injectors but I've read that you need to change a few other areas too in order for the fuel and/or pulserate to be optimum for proper operation. There are others who can elaborate more on this else goto the prom board and do a search on injectors.

4. IMHO if your NOT going to do and major changes like heads, cam(aggressive), miniram, blower and intake stay with the #22 GM injectors else go to the #24 injectors or even higher depending on mods but you'll have to do some tuning to the prom, maybe a lot.

Good Luck!

I hate to waste my 200th post beging for help but please guys some of ya must know

 

Yes they will work fine if programmed for them. The good thig about the Ford injectors over GMs is that they are inexpensive, and they also wont lock up under higher pressures as easily as the GM style. If you are planning down the road to do more mods, then your 24# SVO injectors will be able to support later mods if they arent too crazy..LOL So you wont have to upgrade again later.

 

1) Ford rates all of their fuel injectors at 37psi. GM rates all of their fuel injectors at 43.5psi for 3rd gen cars. (My '99 SS injectors are rated at about 62psi.)

2) Ford's 19#/hr injector at 43.5psi will flow about 20.6#/hr.... Ford's 24#/hr SVO injectors will flow about 26.0#/hr at 43.5psi.

This is why it is very beneficial to install an adjustable fuel pressure regulator on our 3rd gen cars.

3) yes

4) there is no distinct advantage or disadvantage, IMO, either way as long as you dial in and fine tune for any specific setup. However, there may be a small advantage to running a smaller injector, such as, a 22 instead of a 24, but use higher fuel pressure.
