Bill,
Here is the rest of the picture. The cowl is actually three pieces. The bottom
fairing slides into place to feed the radiator ducts. The air makes a 360.
Not my first plan but it seems to be working. The ducts
are in high pressure at any attitude and it would appear they are
getting good air from the prop. With the cowl off and an OAT of 65 I had a hard
time warming up the oil. Stuffing carpet in ducts solved that problem.
