Interesting Bobby, 
Seems to be working. Is there another set of ducts the turns the air the rest of the way round? Or does the air exit the rads to flow into the cowl and then exit rearward like the opening in a conventional air cooled engine? I can't really tell from the pictures, but I wondered if?you bothered with any kind of boundry layer control? Good luck and I hope for your continued success.
Bill Jepson?

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. Bobby

Looking good Bobby,
Interesting inlet solution. Any ducting or a straight inlet to a plenum?? Good numbers.
