One other bit of fuel injector trivia.
A team of engineers at EPA Lab at RTP wanted to convert a VW diesel over to run on methanol without changing the compression ratio.
They reported that they tested several makes of fuel injectors and chose the Holley 12 hole as the best at atomizing the fuel.

At least four different types of port fuel injectors were evaluated for measured engine brake thermal efficiency as well as spray characteristics with methanol, verified with high-speed planar laser imaging. The best- atomizing injectors among the group were racing-style, 36 lb/hr, 12-hole port fuel injectors manufactured by Holley, operating at 4 bar rail pressure. For best startup and transient performance, the injector tip was targeted at the back of the intake valve, from a distance of approximately 80 mm.
