Re: magna injectors
LS1's use these injectors @ 60 psi (there stock fuel pressure),and they rate them at #24 lbs/hr.
They are designed to operate at higher pressures.
They are also common, and a cheap alternative to #24 fms injectors.
However you will need an adjustable fuel pressure regulator to get them to work.
I run mine at 60 psi (vac off), and they are going well.
I do have part throttle detonation, but that is because of a deleted EGR that will need further investigation.
As I have said already in this thread, the money you save with these injectors will be put toards an adjustable fuel pressure regulator.
My injectors cost $140 for eight, and my AFPR was about $156-160.
This still worked out cheaper than FMS injectors.
