That's normal. We're not talking about removing the silencer tube. If you look at the first page, he drilled all those extra holes along the side of the box. That's what we're talking about.

Also FYI, drawing in hot air from the engine bay will not make the engine run hotter. It isn't something you would notice on the gauges. It's a performance issue due to the molecular properties of hot air.

hey fire ranger i have a quick question you know the old style intakes that went over carbs? how exactly do those perform and is there a way to make a CAI for something like that?

No different than a fuel injected engine really. There is usually that big frying pan sized round airbox on top of the carb with an intake tube off to the left or right side. From the factory, there should be an intake tube that goes from that over to the front behind the grill / headlight area (just like on an fuel injected engine). There is no MAF or IAT or other little bells and whistles obviously.

If your engine doesn't have that tube to the front, and they do tend to vanish, you can certainly make your own or buy an aftermarket CAI kit for it. In a case like this though, it isn't a performance upgrade. You're replacing a missing part that used to be there to begin with. The same science holds true regarding intake air temperature and density effecting performance. The factory intake tube is probably not undersized for what those engines are capable of. But performance mods will probably neccessitate and upgraded intake, just like on our fuel injected engines. On my old '84 ranger, I replaced my missing intake tube with flexible dryer ducting.

You may also find a second smaller tube going down to a shroud over the exhaust manifold. There would be a vacuum or temperature sensing valve in it. This is another component that tends to disappear. Based on it's purpose in aviation, I believe it is to counteract carburator icing. My old '84's was missing and it never had a problem.

what about some type of "ram" air, where it is ducted to and thru the hood with some type of reverse hood scoop thing...?

Ram air looks nice, sometimes sounds nice, but usually actually hinders performance due to turbulence in the airstream unless it is done to an exacting science.
As for cold air intakes....
Back when we were running our turbo 4 bangers, we actually tested the cold air idea.
Took a $5.00 digital air temp gauge and a sensor that would reach into the drivers area. At idle, the under hood temp was a good bit higher than the ambient (outside) temp. BUT, once the car was rolling at about 5 MPH, the under hood temp was the same as Ambient. And yes the temp sensor was stuck to the open air filter element.
Reason:: once the car/truck is in motion, the hot air is pulled down and out via the firewall and fresh cool air enters via the front from beneath the bumper / airdamn.
So, the next trip to forced performance, we removed the Injen CIA and actually saw NO change in dyno numbers.

The term "ram air" is kind of misinterpreted imo. The name "Ram Air" suggests that air is being forced into the engine because it is pressurized. I don't believe that will benefit you with hp. The engine can only take as much air as it can, and if your intake has enough air around it, there is no need to force any more air. Also, the air pressure that is built is very minimal, even over 100 mph there is little in terms of pressure increase. I believe that Ram Air serves as a cold air intake. When air is moving it gets colder, and a ram air setup would be ideal in capturing the cold moving air.

There are manufacturers who sell models with CAIs?


Haven't ever seen one on a regular (non-rally or special order) commercial model, to which are you referring?

I don't understand your question/statement. I said if his stock intake pipes were missing, he can buy an aftermarket one to replace it. And as supplementary information, I added that it would likely not provide any performance increase over the stock intake tube without other engine modifications to make use of it. I think you're misreading what I wrote.

Might i remind you that a CAI is nothing like an oem or a short ram intake, which both take in warm(er) air.

You argument using erroneous information by referring to the wrong products.

No it's not. The stock intake tubes on all our trucks draw in fresh air from the grill area. None draw warm air from under the hood. The stock intakes are, by design, "cold air intakes". I realize you will never admit to this simple and obvious fact, so I don't expect any intelligent response as usual.

Mis-information. Our (my year's) oem intakes are behind the headlight assembly, no direct outside contact like you keep mentionning. That area is proned to be filled with warm(er) air at lower speeds since its a confined area very close to a very warm engine bay.

The CAI is nowhere near that location, but what do i know, you're the expert.

That's your opinion. A wrong opinion, but you're entitled to it of course.

Well were here at work looking at what you've done , TBH were laughing ! Not enough air is being drawn into the intake anymore . Basically it's not being forced in . like a vacuum.

Ok heres what you do take a drill and drill a bunch of holes into youre vacuum cleaner at home . hahahaha, now see what happens hahahaha same thing . Thanks somtimes we need a good laugh at work .

Don't forget to drill some "speed holes" into your hood too, just like Homer did. ...
