It does work essentially the same as an airplane wing, where the lift comes substantially from the middle/thickest part of the wing, and not from the trailing edge...

Interesting. So how does the longer diffuser effect the point of lowest pressure? Does it move it forward? Toward the rear or not at all? Or does is create a higher velocity and therefore a larger amount of downforce?
Thanks everyone for sharing your knowledge. I'm finding this thread fascinating.
