Injector sizing question
How would one test to see which injectors are in their car? I replaced mine when I rebuilt my intake but I can't for the life of,me find the documentation on what I bought! I'm sure others may have some random injectors they'd like to ID as well. Are they in "lbs-fuel/hr" for a given delivery pressure? Testing rig of some sort may be required.

Not at the moment, they're buried in the car. I know at some point I'll need to take something apart, I'm hoping to have a method first. I bought them from http://www.fiveomotorsport.com/ but it was three years ago ...

five o is pretty good....they probably sold you the correct 19lb injectors....hopefully with the newer style 4 pin pintle....my S4 ran better with the newer style injectors

You should be able to snap a pic of the part number using a digital camera in macro mode - just unplug the injector connector from one of the front ones (#5 cylinder), rotate the injector around so you can see the part number, and snap the pic.. then look it up or post it here
It'll be something like 0 280 155 xxx or 0 280 150 xxx depending on which series it is. If its one of the Ford Motorsport ones, which used to be popular from Summit or Blue Oval Industries, it might have a Ford part number on the side (e.g. M-9593-C302 for the 19lb ones)
