I am a little confused about the ratings of injectors.
I just put a set of 26# 99 LS1 injectors on my 95 LT1 to replace the 24# ones I had.
The question is, are these 26# injectors rated at 58psi or 39psi.
I read that they are 26# @ 58psi, which become 22# at 43psi.
Now, some people are saying that all injectors are rated at 39psi.

Did I screw myself by getting these 26# injectors?

 

Uh, No. Bosch rates most (but not all) of their injectors at 300KPa. soem are rated t 36, 39, 44 or 45 PSIG. Other manufacturers use different pressure ratings for flow rate testing.

Yes, you may not have the injector flow that you think you do.

 

Thanks Vader.
These are stock injectors. Is there a part number reference I can use to check the specs on these injectors?
