OK, I've got Green top 42# Ford Racing injectors in the Tahoe. I'm told these are the same as in Lightnings. True? I have changed the clips to adapt to the Fords so I don't wanna switch back. Anyway, my questions are:
1. When I want to go bigger, where do I get 50+ pound Ford injectors?

Ford injectors are rated at 43.5psi (Ford rail pressure) so at GM pressure they flow higher. But,....
2. I was told that ALL injectors are rated at 43.5psi because that's 3 bar and an industry standard. True?

If #2 is true then my Ford 42's aren't really flowing any higher than GM 42's because they would all have been rated at 43.5psi. What are Lightning guys using when they pulley down and run out of injector?
Thanks,
Chris

 

I'm running 57lb siemens injectors that are rated 57lb at 43.5 and they also make a 60lb injector.Checkout www.racetronix.com

 

Low Impedance, right? Are these the same connections as the Ford injectors?

 

High impedence injectors our stock PCM won't drive low impedence injectors.

 

I guess $450 for a set of 8 shipped isn't too bad. Any idea if they are taller than the Ford 42's? My Radix fuel rails are already maxed out with spacers and longer bolts with the Ford 42's that are in there now.

 

They fit my Fuel rails with a small spacer and I'm not sure about the plugs.Lingenfelter has the 60lb injectors on special at $49.99ea.

 

This is a better pic of the clip. I will verify before I buy the injectors. I was just wondering if this clip looked like the one you used on your 57lb'ers.

 

The plugs on my injectors look very similar but were a ACDelco part.I don't remember the part number.

 

you'll find that the SVO injectors that you have will flow about 49lbs hr. in your truck. if you keep the radix i doubt you'll ever run out of injector with them.
