After seeing Racebronco's hood at a car meet early last year...I made my own version last year by cutting out large openings just behind the stock heat extractors.
I covered the openings with thin aluminum vents and SS hardware. Took about 6 hours on a lazy Saturday to cut out both vents from thin aluminum sheet metal and cut openings in the Cobra hood.
The next weekend I removed the vents and cleaned up the edges underneath with different grits of sandpaper. Looks very trick. All I need to do is paint under the hood. The bare aluminum was sand blasted but I haven't ruled out painting them black in the future.
I made additional water aquaducts/air scoops that sit below the vents. These were crafted out of thin aluminum and allow water to drain to the front of the valve covers instead of directly over the coil pack covers. In addition, these scoops allow the air being sucked out of the fan to be directed out of the vents.
You can feel and see the heat rise out of openings at idle...especially when the fans kick in. Operating temps dropped about 10 degrees across the bored during normal high-heat summer commutes.
To date, this was probably my best cooling mod.
