Vent Rear of the Hood

Dana67Dart said
The base of the windshield is actually a high pressure zone. Open the under dash vents air comes in.

Lifting the back of the hood might change that?

But you also might be pushing engine smells / exhost fumes I to the car?

Not saying it's a good or bad idea just thinking through the what ifs

Yes, I'm aware of the high pressure zone. One reason that I want to do it. I don't know if the under hood pressure will be greater.
I'm not worried about fumes, it's mostly a track car. But with forphorty's idea, it should only lift at speed.

Something I have been toying with, what is the greatest source of heat in the engine compartment? The headers or manifolds. 600+ degrees, isn’t it easier to just keep the heat in the exhaust stream, at least until it’s under the car. Thermal Ceramic coating inside and out the headers or manifolds.

I agree, a lot of it is about heat. Coatings are out of my budget. Wraps are a mess. I currently have an open element air cleaner. I'm saving my money to get a cold air set up like Spectre or RamAirBox.
Part of the reason I want to vent the hood, other than to cool under hood temps, is to maybe relieve under hood pressure that could allow mph to increase?
So maybe the combination of the two (cold air and venting), will be better than one or the other.
