My experience of pencil jets for what its worth is that they are very phase sensitive. Having said that it was on a 4 valve engine so probably of little relavence.
It was also very sensitive to position and relied more on air motion than vaporisation within the port.

Also you can make a pencil jet out of a conventional injector by grinding the cone off the end of the pintle (as long as it isn't a multihole type obviously!)

Good luck as it will be interesting.

I still like the easy route of plenty of wall wetting and careful transient mapping but I don't care about fuel consumption.
