Default Hood mods (scoops, heat extractors, etc.)

Has anyone modified their hood by adding any sort of ram-air scoop or heat extractor louvers?

Several years ago I saw a hood that somone had added the hood hardware from a late 80'* Trans Am to their Bonneville and it really looked nice - like a factory hood - it did not look cheesy or out of place.

There is no ram air effect until above 120mph. That'* why I chose vents instead. I know I can blow leaves out of my vents by turning on my high-speed fan override. And in the summer at a stoplight or at the track, at idle I can watch the heatwaves rise out of them.

I recall I measured the heat one time coming from them. I'll see if I can find it.

Keep in mind mine and John'* are functional. And they're the only two cars on this Forum with functional hood mods. All those above that you see are non-functional appearance mods.

Can't find the temperature data. May not have posted it. But Greyhare and I measured the temperature of the air coming out after a 15 mile commute on a 60 degree morning at over 125 degrees F IIRC. If the heat comes OUT like that, the engine is running cooler.
