Ok, here is a freakin' novel! sorry for the length!
We got our '84 T/A about a month ago and it is great! I am getting to know the car and planning just a few upgrades as time and money allow. THe car has the functional cowl induction setup, however, the P.O. removed the solenoid and, *i think* the induction unit that mates to the air cleaner. I think he got a little "overzealous" in trying to make it pull cold air constantly, not just under WOT.
I do not want to reconnect the solenoid either. I just need to figure out how to seal off my air cleaner assembly so that it just pulls air ONLY from the cowl opening and snorkel. Right now it has nothing to isolate the hole in the lid from the hot air in the engine compartment, so that is what I want to fix.
I have searched, but have been unable to find an article dealing with fabbing something like I am thinking of. Here goes, I am thinking of welding a plate of aluminum or chromed steel under the hood matching the induction channel with a hole cut out that matches the outside diameter of the cleaner assembly , then attaching h.d. foam or something to seal the cleaner assembly to the cowl induction, making sure my carb only gets cold air!
What are ya'lls suggestions?

 

I was asking about something like this before, maybe my thread can help you out?

Edit: Most specifically, the link I give on my first post.

 

Thanks! That is just about exactly what i am looking for! I owe you a cold beverage!

 

do something like this

That article that Sonix mentioned from highoutput.com is what I had in mind also. During cold or rainy weather you could just block off the hood buldge so you're just taking in air through the snorkle(s) under the hood.

 

I made this in about an hour back in 1999 and it draws all cold air through the scoop.

Is this about what you were thinking?

 

What kind of "foam" is that surrounding the air cleaner and where can I get some ?

 

From summit racing. Moroso part# 97070, 5' length, 4" height.

 

hmm, yea that's the idea.... The idea on that website I linked uses just a big air cleaner base, and a small air cleaner top, so it'd have less flow area then yours, but looks a little nicer... however yours wouldn't need to screw up the hood... maybe I'll do that way
Is that just a plate of AL bolted onto the carb, then the air cleaner sits on it? that is nice and simple...

 

I used a thin piece of sheetmetal from lowes, cut a large hole in the middle, and welded it to an air filter base. I added a 3/4" or 1" lip around it (mcmaster carr sells long strips of it so no tedious cutting required). I also bent it in the back to both clear the distributor and for extra strength. The foam was glued on with 3M weatherstrip adhesive. My neighbor helped me trim the foam once it was bolted on. He used one of those really sharp carpet knives which cut the foam really well.

 

looks sharp and a good beer of choice as well.

 

Yup that is essentially what I did too, except I pop-riveted it to the bottom air cleaner assembly, essentially turning it into an extension of the air cleaner.

Mine was made in an hour with an old air conditioning duct, kevlar gloves, some duct tape, tin snips, some closed cell neoprene industrial insulating foam , some 3M weatherstrip adhesive, and a magic marker.

Ugly yes, but cheap and effective.

 

I was thinking of doing something silimar...Good thing I used the button!

Anyway, after deciding not to go the CFI route I had planned earlier, I have decided to keep my current carb setup. I have the exact same K&N air filter in the photo above. Now while the filter can draw in more air, my concern is that engine bay generates A LOT of heat and it's just sucking in all the hot air. I have the power bulge hood, with none of the hood induction parts attached, so it is just open to the outside. I'm sure very little if any outside air is getting inside to the filter and if it is, it's not much to do anything. I wanted to know if I could just use the carb hood induction setup with the same air filter I have or will I have clearance issuses? Would I have to get a different filter?? And lastly would there be any difference in performance as far as the heat goes compared to the restriction of the hood induction unit being used? I know heat is your enemy, however with a more restrictive setup would it even make any difference if the air was cooler/more restrictive vs. hotter/less restrictive?

 

How large is the opening of the hole for the power bulge hood?

As far as clearance issues, get a large sheet of sturdy cardboard and some masking tape, and mock it up. I used a 14" radius for the front section (1/2 circle) with the carb stud being the center, and then went straight back until it hit the firewall.

 

It is the stock opening.

 

Anyone tried that setup, i.e. foam but with ram air ? Would it hold up at higher speeds ?

Still trying to find somewhat decent foam, damn Home Depot didn't have anything as usual.

 

How big is the stock opening? 3" by 6", etc etc.
