Do you know what the :

injector rated fuel pressure is for ford 30#, 36 #, 42 #

what the C5 fuel rail pressure is (I thought it was 58#)

F-body fuel rail pressure

2004-05 GTO fuel rail pressure

thanks

Is this a question?

My understanding is Ford's run 3 bar pressure which is about 45 psi. We run 4 bar which is about 60 psi. So that injector rated at 30 at 3 bar when applied to 4 bar flows more. Say 36 or so? I have never done the math though.

^^^^^^ correct

Knowing our 4 bar pressure is 58.xx and three bar is 45xx(IIRC) you can figure it out here >http://www.csgnetwork.com/fiflowcalc.html

i think this is the answer Im looking for

high the injector is rated at 39.15FP
the rail pressure is 58.. in the c5 and all ls f bodys.
the ford 30# injectors will flow 36 in your rail.

another good page to save.
OK my numbers are right

Ok here is the scoop. All injectors are rated at flow capacity at 43.5 lbs of fuel preasure. So if you have an injector that flows 30 lbs at 43.5 lbs if you increase the preasure to 60 lbs. The injector will flow 35.2. A 36 lb injector at 60 lbs would flow 42.3 and a 42 lb injector will flow 49.3 at 60 lbs. Remember injectors should not exceed .8 DC to prevent lean outs. Remember all injector flow ratings are at 43.5 lbs not 45. At 45 lbs a 30 lb injector flows 30.5 slight difference. A 30 lb injector run at 58 lbs would flow 34.6 Hope this helps tom
