Functional air intake on c pillar?

I know at least somebody around here did (blue cat). Made custom inlets, and had an oil cooler behind it (if I can remember correctly). I could look whether I could dig up the thread.

I've not found the thread, but looks like I saved a picture on my laptop

They look great, but they're one of a kind if I understand you right.

Yep. Unfortunately I can't remember who made them.

I like the idea myself, but the above design suits a modified cat only imo. I'd rather go for something which would look more like the original fake ones. If I had a spare set of those, I'd had a play with it myself.

No-Quarter, quite a few have tried. And the consensus is, at anywhere near legal speeds, the air flow is OUT the scoops from the engine compartment. Somewhere around 140 mph, a small amount of air begins to be 'scooped' in, countering the normal flow, and by 170 mph, there's enough pressure to rip the scoops out of the body- as they're only are held in by friction of the rubber sealing boots. Your neighbors in the Swedish Club did rolling tests with tufts of yarn a decade ago to prove the boundary layer on a Pantera's side is about 4" thick. So any functional scoop should stick out further than that- hence the elephant-ears which look awful but function best.

If one used scopes like the one pictured, would it not provide a cool source of air? I think we all agree that you wouldn't get a ram air effect but what would it hurt as a simple cool air intake?

Scott is right. There is a difference between "ram air" and "cold air", they are two different things, don't confuse them. Ram air will only benefit a car traveling triple digit speeds, and the scoop must be mounted high enough to be in "clean" air. But cold air can benefit any vehicle, even street-only cars. Vehicle speed doesn't enter the picture and scoop location is not as critical. For evey 10 degrees F the temperature of the air inhaled by the motor is decreased, horsepower is increased by 1 percent. That's probably 10 to 15 horsepower for most performance cars.

Although the scoop pictured in Kid's photo is a "poor" ram air scoop, it is an excellent cold air scoop.

I know next to nothing about aerodynamics. But I don't see any other cars with elephant ears, Ferraris, Lambos etc., they have holes to suck in air to their engines, and those holes are integrated into the body, normally not sticking out at all?

I have an extra set of gills to experiment with and - like Mikael, I would wan't it to look original. Thought about cutting slits at the bottom of the gills in a circular pattern, and then fabricate a discrete funnel to direct the air.

But, if airflow is OUT of the scoops under most conditions as Jack mentions, then will it make a difference? I guess, exiting hot air from the engine bay will also lower intake air temperature, but wouldn't the effect the gills would create be marginal?.

Those elephant ears I believe were developed by Detomaso too.
Aesthetics being a function of function. If they work...they're beautiful?

The NACA duct principle maybe??

I reduced my air intake temp by 80* with my scoop. Easy to see on my laptop and intake temp sensor.

Holy smokes! That's a big deal. You can probably run a few more degrees of timing on pump gas as a result. What were the actual inlet and ambient temperatures?

Best,

The air should be ducted from the scoop directly into an enclosed air cleaner assembly. The motor will then "suck" cool air from outside the engine compartment, via the scoop; thus it is impossible for air to flow out the scoop.

If you'd like to play around with aerodynamics a bit, try wetting your fingertip, then rolling a window down just an inch or so and stick the wet finger outside more-or-less in line with the gills. You'll be surprised how far out you have to reach to feel the evaporation-effect cooling your fingertip. I suspect the Pantera's side boundary layer is so thick partly because of the windshield trim & gasket, and the tall rain channels down the front pillars. There may be some effect from the depressed position of the door glass, too. But its a pain to remove the channels since they're one piece all the way back, the door gaskets seal to them and there's a 2ft long welded seam on both sides of the roof that's exposed if you pull the channels (I chose not to cut them). Other brands have no (or smaller) pillar rain-channels, flush side glass & windshields, and other body tweaks not easy to install after the fact.

I am using small side scoops in place of the rear windows that will have duct hoses going into a sealed air box. I don't know if I should call this a ram air system or just cold air induction.

Jim I think it will be cold air induction, not ram air, but I know the finished product will be top notch.

I have a set of "scoops" that I bought many years back. I was told they were made by Hall in the 80's. They replace the louvered sections next to the quarter glass. They are formed out of sheet aluminum and the outside is primed with black. The problem I see is that they do not have a provision for the fuel filler. I can send pictures. For sale.

Well what do you know, here's a set on Ebay...
