Importance of Injector Cone Spray Patterns?? I've found 3 injectors with the following specs:
30lb @ 4 bar (14.2* spray pattern)
42lb @ 4 bar (21.9* spray pattern)
50lb @ 4 bar (22.4* spray pattern)
Does anyone know what the stock spray pattern is and how much we can deviate?? What problems (advantages) with different degree patterns?

Re: Importance of Injector Cone Spray Patterns?? Mark,
Injector spray pattern goes in the basket with spark plug indexing. It doesn't matter a hoot.
If you are an OE and you're worried about the effect wall port wetting on emissions then you'd start looking at such things, but as enthusiasts we're essentially no better than a bunch of neandrothols trying to work on an f-16.
The difference in the larger injector's slower actuation time is going to cause a much more significant effect on how the engine runs than the spray pattern, and nobody worries about the actuation time.
