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.

 

I have started making my prototype. This is a non working prototype made out of card board. After making it it was too tall so tomorrow i am gonna make it shorter. I am going to make two of every piece so i can take the unused templates to a metal worker to have them cut. From there i will powder coat the device on the carb, and the "pipes" too. I dont want to share pictures of my design becuase i dont want anyone stealing it. ( not anyone on the forums just other people. This is the internet.) Once i have everything built it will be time for testing. i will do two dyno runs one with a normal air intake and then my device. With all the test results and proto types i will then apply for my patent.[8D] I am going to get this patented. From there on out i can safely show my idea to companies knowing they cant take it.

I have realized that there is one design flaw in my pipe routing, and the postion of the pipe fittings on my Carb "cover" screw it im posting pics.

 

Ok i have solved the one of my problems. It was the "cover" slipping over the carb and block my two pipe inlet holes.
My next problem is how to run the pipes. I want to do it so that i dont have to cut any holes. I am thinking about on the bottom of the car making a scoop type device to push air through the pipes. Im gonna use 2.5 inch exhaust pipes for the piping.

 

Now anyone of us can actually do just like tyler is doing, and build our on. It's Just we're to lazy to do it. Now that it's getting colder, i might not til next spring.
