This is from an Aussie Commodore (GM) from about 1984. The plate shown acts as a scoop to pick cold air up from the grill, and force it into the carby. it has a seal arond the top edge to seal against the Hood inner. You need to use an open type aircleaner (ie HIPO).

I have the feeling that someone is going to work the bugs out of all this! I can't wait to see the results.

Now, there is a great idea. But, expensive and impractical because it would have to be removed to work on the car. You also have to somehow alter the hood to fit it in there it seems. Otherwise, how does the air get in?

You need to build a real prototype that actually works that is unlike any other, then apply for a patent. Big bucks could be made if you can get someone to actually mass produce them.

i have heard that turn signal hoods on 67-68 have the same cooling effects as the 03-04 cobras with the same reverse type vents. It has been debated for years that, the turn signal, do not have function, but just recently have heard from numerous people that that they do have function, and do help direct heat out of the engine. I dont know im just rambeling on again

The shaker hood (69-70) or the operational NASA hood (71-73) did exactly that cold air. I have a F250 Diesel that is my daily driver, and I built a homade cold air intake for it. For the mustangs I have seen something similar to the blue air cleaner posted only in black with less restrictive openings.

Help me understand why the cold air is so important? Some articles I have read say the engines wants warn sticky air. I assume this means is uses less fuel this way.
Thanks

Cold air is more dense, so when it is compressed it makes a slightly higher psi, so when the combustion process occurs, you get greater HP (although slightly) and slightly better gas mileage. My diesel has an intercooler as does the Buik Grand National - to get cooler air to the engine. Obviously, you don't want the air too cold, but cooler.

Yep, and all modern engines have filtered cold air into the intake. Duhh. Maybe the modern engine engineers figured out this was that best air induction system for combusting gasoline in an internal combustion engine.

No the hood doesn't need to be modified. The air is picked up from over the top of the radiator, basically straight from the top section of the grill. Because its the whole width of the grill, there only needs to be a small gap between the hood and the grill, (which there is) to allow enough air to get in. You also get the added benifit of a ram air effect as the car is moving.
In terms of cost, these ones are made of fibreglass, and i wouldn't think it would be too difficult to fabricate one (even if it was initially using carboard, body filler and fibreglass, and some plasticine to get the seal to the hood inner correct.
To work on you engine, its no more difficult to remove than a normal aircleaner, as the std aircleaner wingnut holds it down (plus some sort of fixing to the radiator shroud area)
These scoops were used with success on both racing, and road performance versions of the above car. No-one here probably know of him, but an Australian Motor Racing Icon, Peter Brock, developed it.

Why dont we do just like they do on the new cars? Have a scoop, run it to a box mounted by the radiator, and then run a hose straight to the carb.

That's the plan. It's engineering it to fit into the engine compartment of a early mustang that's the problem.

What about something like this:
I know this is an EFI engine (a viper engine to be specific), but the general concept would work.

Thats about what i was talking about.Except putting a Air filter box on it, or would that be too much restriction? I was thinking about totally removing the air cleaner off the carb though.
