I'm just wondering about the differences in spray patterns of the larger injectors out there, and the results of those differences, if there are any. I remember reading about a test of different injectors/different placement, etc on a smog check machine, and the best emissions were achieved with the lucas disk "laser beam" style of injector aimed directly at the back of the intake valve. However, on a honda, with 2 intake valves per cylinder, that would be impossible to achieve. You'd have to split the beam in half. One day I was curious about this, and was test spraying some injectors with an old fuel pump, and I noticed that a set of injectors I have from a toyota do exactly this, they have 2 holes for 2 different spray beams. I think that is really cool, and all injectors should be like that for engines that have 2 intake valves per cylinder. I have never seen a honda injector like that though, do they exist?
If they don't exist, what other spray patterns are available? I'm looking at buying a set of rc engineering 1000cc units, and I'm curious what they spray like. I'd rather have the normal 30degree spray pattern than the laser beam, if I can't find an injector that splits the beam..

 

The BOSH injectors from a Porsche twinturbo have four holles in it forbetter spraying.
