Darin (nice to see you over here) - I have a question for you on wet flow.

On most of the EFI systems at high rpm they inject onto the back of a closed intake valve to get enough Injector Duty Cycle to meet fuel demands. I am curious on your tests did you get any clear indications about what happens to pooled fuel during the first 0.010 of valve lift? Does it just hose down the cylinder wall next to the valve or is it blasted into a finely atomized mist during this period.

I am thinking this is the period most likely to wet down the surface of the combustion chamber and the piston crown and am curious where or if dimples on a specific area of the combustion chamber (ie just outside the intake valve seat) might help get this fuel blast properly atomized and suspended in the intake charge on the EFI systems.
