REFLECTOR: Cooling Question

[Brian Michalk via Reflector]

I have armpit scoops, with a SCAT duct feeding plenums in a top down 
configuration.

I've had high temps, and do not know if these temps are because of other 
issues.  I'm at the point now where I am starting to work through this 
issue.  I have a differential pressure sensor and will be making some 
test flights getting pressure data across the cylinders.

As luck would have it, I have a spare top cowl that I am retrofitting to 
have a top down NACA scoop similar to the stock factory design.  If it 
works out, I should be able to swap out between the two designs.  I'll 
collect data and forward it to the group.
