Well, that's how long it's been since I made any progress on it; I 
forgot the pun in the original email.

Tracy got it right. This will hopefully be the diffuser for my oil 
cooler. It will mount in the left nostril similar to Tracy's 20B 3rotor 
setup. Same core, with ~10"x10" face. If it 'almost cools' a 3 rotor, it 
should be fine on a 2 rotor. The radiator is still on the right side 
with an extreme wedge style diffuser. I found that I had to use a 
turning vane in it, to get even flow through the core. The turns are 
even more extreme with the oil cooler (much shorter diffuser), so I 
decided to include the turning vanes from the git-go (Southernism). 
Still a few more steps to go before I can check the flow, but I'll post 
a video of the flow once it's completed.

Charlie
