From an airflow to the radiator standpoint, the lower opening does everything. Blocking the top made little difference on warm up time or operating temps. On the Jetta you can block both anyway, and just leave the small slot in the very lower valence open, its enough airflow for anything but hot summer days.

Treb, any new simulations run or data compiled from previous runs?
I'm interested in seeing a model of your Kamm shell.
However for visibility and functionality reasons, I still like the novel spoiler design myself. But I need some data before I start building! What are the plan for future runs? I know you are swamped with finals, etc. right now.

The pace of which this thread originally moved has me jonesin' for more data/results!
