home made ram air?

[7000rpmisheaven]

I would like to make a ram air intake for my 4bbl carb. I could buy a fibreglass scoop and cut a hole in the hood. But then what. Anybody know a way I can do this. Are there ram air kits for 4 barrel carb engines. If there are, where could I find one.

Flip the air cleaner cover upside down.

I don't think I understand. What will that do?

It is kindof a joke. In high school auto shop it was the thing to flip the air cleaner cover upside down which cheated the tube on the side. It really didn't do ****.

I'm not knocking you dude. It just seemed so titty on a 69 500.

I am about to do my third air induction system. All have been done with scoups from the wreckers(82 stangs) and cutting a hole in the hood.

The first was open fresh air. The second was sealed ram air. My third will be sealed cowl.

The ram air is great but make sure you use vac. secondaries as the mech pop open to fast and cause the car to lean out and bog.

To get a centre point on your hood. Put a longer piece of ready rod in the carb and sit the hood on it. It will dent the hood in the centre. Then use a large compass to trace the desired circle. Cut the hole using a jig saw or air nibbler. I used a Ford BB air cleaner bottom(about 20" dia) and a 14" air cleaner top. The dual snorkel air cleaner works too. I sealed the fac. openings on the bottom plate.

Get some door rubber seals for sealing material and light gauge sheet metal for the top part of the seal. Close the hood with the bottom plate/rubber in place. Curl the sheet metal and insert with rubber through the top till it butts up with the bottom plate. Tach weld around the sheet metal, cut flush put scoup on and voila ram air.

Hope this helps.

Thats perfect. To tell you the truth I had wanted to use the 82 hood scoop. I had looked at many aftermarket spoilers but did not find many that I liked. The 85 body has mostly striaght square edges. Some of the aftermarket scoops were very curved. I dont think that they would look right. The 82 scoop just looks right.
Thanks for the help

Make sure it's an 82. An 83 scoup is too big.(The reversed style).

below is a picture of the Buick I used to have, and the first cold-air set-up I had on it. I had two vents from the fenders of a Trans Am mounted into the hood to resemble the Buick GS hoods. On the carb was a kit that I bought, but that could be home made easily. It was a metal rectangle, close in size to a McDonalds tray, with a hole in the center to fit tightly on the carb. It was held in place by a Weiand foam triangle air cleaner (open element across the top). Along the edges was a piece of 1" thick foam that sat 3 or 4 inches tall, and sealed against the hood. This worked excellent until it rained. I eventually bought a fiberglass Cobrajet Mustang hood scoop, cut a hole in the hood that was 1/2" wider that the circumference of my Moroso air cleaner, and then boxed the forward end, creating almost a keyhole shape. Then I mounted the scoop over the hole (the air cleaner rose through the hood about 2 inches). There are even better ways to do it, but I ended up getting rid of the Buick (521 horsepower wasn't enough for a 4400 pound car).



Take care,
