That looks like a Pikes Peak racer to me.
TONS of front downforce on those babies!
If I can get my hand on a fiberglass/carbon fiber hood for a Ford Tempo, I could probably make more aerodynamic hood vents similar to that there.
For my car, I've decided to forgo the blunt air-dammed front end and have a smooth skid-plate-like coroplast pan under the bumper, remove the horizontal stock air dam, and set the end of the coroplast low enough to get the lowest part out of the immediate airstream. I'm also going to be making a small splitter lip to help with reducing lift.
