Here's what it started as, when I first decided to do a grill block:

I was still having overheating issues with the huge hole I ended up cutting, plus I read some more on here and determined it's a bad idea to push air under the car rather than over and around it, so I revamped things. Here's the new version:

I still have to work on the belly pan today, and figure out how to get air to go
through my radiator. My air intake started out as a small hole, about 1/2 the area of the license plate, and grew as I was driving home from my in-laws saturday night and the car 's temp gauge wouldn't stay in the normal range. Even with this monster hole, the car wouldn't have made it home unless I turned on the heater. Something's gotta be better once I make some ductwork forcing air through the original grill. Here's the underside.

And here's what you see if you look slightly downward through my intake hole now..

If anyone's got ideas or suggestions on helping with cooling airflow or if the hole is big enough, I'm open to whatever you have!
