We suspect backyard Bob modified these side feed injectors to flow more. The problem is that they don't flow very even as per report, although there is more to it, as it is hard to see in the picture but they are all in different rotation, or sequence, in reference to the injector plug location. The flow test showed even worse as not matched very well and they also did atomise very well, more like jets and pointing in different directions. See picture of one of the injectors magnified showing uneven hole size and spacing.
Seems someone with a set of wire drills and a pin-vise had a little too much time on their hands............. E
