Bearbvd, thanks. I am pretty familiar with NACA reports. That's why I would be excited to read one that had information on this. However they are tricky for the average person (obviously not you) to read because they use aviation, not automotive terminology. There seems to be more misinformation from misunderstood NACA reports out there than good information. This is especially true with water injection information.
