Denny,
Even the folks at "Eagle Research, Inc." tout their Electronic Carburetor Enhancer (in combination with their original Carburetor Enhancer) as allowing an engine to improve MPG by up to 25%. That would get us 15-22 MPG (at the most).
I wonder if the stream-lined style of an A-D panel body would be reducing the turbulence and result in a more economical airstream? (This is not something that I normally think about when I am awake, asleep, or in a mind-altered state).
