Subject: Pusher rads 3D

This is a variations on an idea I had about a year ago.
Since boat tails are lower drag on pushers than up sloped ass ends, 
boat tails are a good place to put two small rads in V formation.

On hindsight based on recent test box data it is better to 
use venetian blind cowl flaps rather than the two cowl flaps 
shown in the original gif. The duct feeding the two rads is
a constant area P51 style duct with boundary layer bleed. 

Here is an exploded 3D view, the original gif and a picture
of Gary Spencers 236 MPH Ford V8.
