Mike, I’ve got a 13B NA, flying a “Chubby Cubby” – 110 mph airplane.

Figures I'd make a statement like that and have somebody prove me wrong. I cant remember Jeff, what airframe and what engine are you running?

Thomas,

I like your approach to the problem, I see nothing but positive outcomes in proving the concept (one way or another). 3.5" is ( I believe) OK, the thick verses thin debate is like comparing apples and oranges given the different applications of cars and aircraft. I don't know what speed your looking at in cruise but 3.5" should be good for a higher cruise. I believe some have used 3" cores successfully. However I'm no expert but I look forward to the outcomes.

Mike,

The graphic is not a true representation of the final design. It merely depicts an unmodified P-51 scoop that has been rendered in CAD, scaled 61% and rotated lightly in the clockwise direction.

My actual radiator design has a frontal area of 203 sq in and a depth of 3.5 in.

As stated earlier, the purpose of the post was to announce my willingness to share a software program that I had developed and found useful.
