Are the Ford Racing and svo 30# injectors the same? I want to make sure I'm buying the right part. This is how they are listed:

Ford Racing High Flow Fuel Injectors
Fuel Injectors, EV1, 30 lbs./ hr., 11-18 Ohms Impedance, 12 V Saturated Circuit Driver, Ford, Set of 8

Yes, they are the same.

HSV-GTS-300

FORD RACING

30LB FUEL INJECTORS
Code: M9593B302

30LB MATCHED FUEL INJECTORS
Code: M9593B302F
TYPICAL PRODUCTION INJECTORS CAN VARY IN FLOW RATE AS MUCH AS 6-7%. THESE KITS TYPICALLY VARY LESS THAN .5%. THE RESULT IS IMPROVED FUEL CONTROL AND OPTIMIZED PERFORMANCE.

Ok, I have a question regarding these as well. What is the pressure difference between FORD and GM? I have heard that on an LS1 that these are more like a 36-38lb injector. Someone clear this up for me please....

You just have to find out what fuel pressure the SVOs were rated at, and then do some calcs to take into account that our fuel rails operate around 58psi.

Google Results.

Ford injectors are rated at 2.7 bar or 39.15psi


The equation:

Actual Flow = Rated Flow * (SQRT((Actual Press + Manifold Vacuum) / Rated
Press)))

So as an example using 58.01 psi (which is the stock F-body fuel pressure)


Actual Flow = 30 lb/hr * (SQRT((58.01 psi + 0 psi) / 39.15 psi)))
Actual Flow = 36.51 lb/hr

But then according to the Ford Racing Catalog :
Just below the pic and data for the matched sets of injectors it says

" Note- These injectors are flowed at 40psi differential pressure, and a flow data summary is included in the package"
