In stop/go traffic, the vents in the undertray it resulted in a small difference in cooling temps (~1 degree C) but a slightly bigger difference in air temps and related to heat soak.

Also, I recommend using some of these hose clamps on the silicon coolant hoses:

I had tried using some expensive, high quality, worm type hose clamps and they would loosen over a few heat cycles. These Breeze constant torque clamps work incredibly well and never loosen up.

Thanks for the real-world feedback both on the undertray and clamps. I may switch to something like the clamps you're specifying. Had my first real-world driving experience yesterday when I took the car on her maiden voyage to our club picnic (30 miles round trip). All went well and temps were extremely cool, especially given the fact that I was running without the undertray. Temps can only get better once I get that completed and installed.
