I just checked the Bingelis books, and it wasn't there. Plus, a 60 lip looks out of place and draggy. I did the one flight with the "lip" and removed it, proving nothing. Yesterday I built a brace that screws to the firewall, and projects down to contact the cowl, and this will keep the cowl from being blown upwards, if indeed it ever was (without the added lip, that is). This provides two things....it keeps the cowl a bit further away from the pipes, and provides a fixed outlet area, not a variable one.
