Anyone have opinions on which is better under higher boost levels (15psi +)?

Danno here, posting on Anders account at Nicole's house.

Talk to the folks at RC Engineering on their analysis of pintle vs. disc type ends on injectors. I prefer the Delphi injectors because they have better vaporization. The 6 holes on the Delphis allows better vaporization of fuel at the higher flow volumes. The 160-lb/hr injectors I have spray a solid stream of fuel for 30-feet! Not good for vaporization.

There's a picture somewhere on the internet comparing the spray-pattern between pintle vs. disc-end injectors.
