I always heard it didnt work up until like 200mph
I was thinkin an inline filter, or a filter in the scoop

Just found this wading through my old website.
http://edge_krusher.tripod.com/template/link.html
These are some templates put up on the forum a few years ago.
Probably hard as hell to find now.
This is what I based mine off of.
BEWARE of popups. It's tripod

...94% correct.
Ram air is rather effective, and it's been proven repeatedly...
http://sportrider.com/tech/146_9912_ram/ <--bikes, but concept is the same.
Too many people whining because someone's opinion or theory differs from theirs...besides, I can only say the same thing so many times before I give up on the idea getting across.

At 150+ MPH you'll notice a difference IF it's sealed, if the opening has a different shape and it's bigger than the tube so it essentially catchs it.

No it's not being forced in, the speed at which you're going isn't enough to make it forced in.
This is why they use it on aircraft such as the F-16 and F-15 because they reach those speeds very fast...
This is all coming from a friend who was in the Airforce Academy for college and is now flying a unspecified air craft. He was at the Academy doing tests to see if it was real.
Until then, believe what you want but I'll keep laughing at the ricers who think their l337 ram a1r system gives them 50 hp.
I'll see if he'll register and post the graphs for you, I formated my computer since that discussion.

There is more to take in as far as "Ram Air" goes. If at any point the airflow pulled in by the engine is more then your intake system can supply (i.e. the tube past the throttle body and your air filter), a ram air system will increase throttle response and to a lesser degree available power. Any point below this (unless you're travelling at enough speed to compress the air, which is a pretty good clip) is going to be inconsequential.
That said, most properly designed air intakes will flow more air then the engine is capable of using, making ram air much less effective as any performance boost. A constant supply of cold air certainly doesn't hurt anything though.
Want to test this? Stick your head out the winder at 50 mph and open your mouth, see if it suddenly fills your lungs with dense air. You'll find all you get is bugs. 
I'm not saying ram air doesn't have advantages, it's just simply not a quantifiable amount in most applications.
Makenzie,
Do you actually have a degree (or any advance college education) in physics? It certainly seems like you're just using the "because it seems like it" school of physics. I swear sometimes the people on this board would argue the earth is flat because they can't see it curve.

i was thinking of a cold air intake along the line of mach 1 shaker units. it would only work with a t2 hood but i think it could work. i know where the scoop is located is not a high pressure zone but i think it would work better than the stocker. does anyone else see this as being a good idea?

THANK YOU! I finally found someone on here who knows what they are talking about.
True, the cold air is nice, but it's not FORCED AIR that you're describing as giving the power increase, it's just the colder air.

The analogy of sticking your head or hand out the window of a moving car is inaccurate. You are not feeling more air pressure. You are feeling more air force. There's a difference. The air hitting your hand is still at the same pressure as a nonmoving car. Nothing has changed it before it got to your hand. It is just exerting a force over a large area which pushes it backwards. This is not pressure. You don't need airflow to have air pressure. Go look at an air compressor tank.
Ram air is indeed possible but it isn't as simple as sticking a filter into the airstream. This does nothing to change the pressure. If you exceed the amount of air that the engine needs, it will just go around the filter. For true ram air, you are really trying to do what a trubocharger does but only on a smaller scale. You are trying to increase pressure. In order to do this, you need to slow down flow without losing any of the air. The way to make ram air work on a car is to have a larger inlet than necessary. Then you need to have it feed a chamber where the area expands. This will slow down the air causing it to compress a bit. The air pickup point for the motor needs to be in this area of the box where flow is slowest but pressure is highest. The concept does work. However you will not see a usable benefit on the street in terms of power. You have to be going pretty quick just to show positive intake pressure and even this speed is above legal speed limits. After you get over 100 mph or so it will start to get usable and the faster you go, the better it will get. It is possible to increase the vehicles total top speed ability using a true ram air system by around 3 mph or so. At least this was the number that Racing Beat figured out at Bonneville on their n/a cars. 3 mph when you are going 150+ is quite a bit of extra power. Remember this is a much greater effect at really high speeds and practically nothing in comparison at lower speeds. Do you really think you'll feel it? Good luck trying. You can't dyno it to prove it works either as a dyno doesn't take into account airflow.
It is possible to get a slight economy benefit at freeway speeds with true ram air as the engine isn't demanding much airflow and you should have sufficient airflow to increase the pressure slightly. This is actually being seen on the RX-8's with the Racing Beat ram air duct but increased power ins't necessarily perceived. The more you open the throttle, the more air the engine needs and the less the pressure will be in your ram air box. You need to go faster to compensate.
Does ram air work? Yes. Is it usable? In what way? Maybe. Maybe not. If you are looking for a noticable power increase on the street then no. For street use worry more about getting the air source out of the engine bay and less about if it is ram air.

How about you kiddies stop bickering about this ram air subject, start a new thread for that. More pics of where you're filters are located, and what the box looks like, please!

Tintake of a jet is usually WAYYY back in the back...but you knew that right? Didn't think so.
SOME jet's have the ram-air system on them, just becasue you see a huge hole in the front of a jet doesn't mean it's your l337 ram a1r 5yt3m that's where it's routing air for aerodynamics.

F16/F18 intake location is a function of aerodynamics as well as allowing maximum air to the engine to allow for super cruising, etc. (yes I'm aware that not all of models of these planes are capable of SC).

No, what I'm talking about is yes, it does route air through there but there's not a HUGE CONE in the front of that intake that sucks air, it's routed very differently from a car.
