James:
	Although we haven't done extensive testing yet, we have benched some 
injectors at varying pressures and pulse widths. As we suspected before 
setting up the bench, the generally accepted formulas are not very accurate. 
An increase in pulse from 2 ms to 4 ms does not exactly double flow. Nor does 
flow vary directly with the square root of the pressure. The dynamics of 
opening and closing are affected differently by pressure for different 
injector types and sizes, and obviously flow is affected by the percentage of 
the pulse a particular injector takes to open and close. Math is good for 
ballpark estimates, and injector selection, but bench testing and then dyno 
testing are unfortunately necessary for final tuning.
