Ractive Ram Air system. - Toyota Nation Forum : Toyota Car and Truck Forums

Should I slap on of these on to my Dragon intake? I was thinking about mounting the ram air on under the driver side turn signal where we have that gap in the Camrys.

Naah, ram air wont work on a camry, you gotta be going at around 120mph(200kph) to get it to work so that you could feel the effect. You'd just be attracting more rubbish, and stones are bad because they can go through the filter.

Camry_rider · 09-02-2003, 12:44 AM

Thats where I really need the power, around 80+ mph. Stones will not be a problem. If you look at the area below the turn signal you will see a area which has a oval shaped hole with a peice of plastic in the middle of that. I belive it will be pefect for the system, if I can get the hose from the intake to that without much headach.

ramair wont really work at 80mph, I mean you really gotta be going VERY fast to get the pressure wave to charge the air into the intake. its 200+kph (120+mph) territory where you gotta be to get any effect. Useless.

Im not trying to start an arguement with you, but why is Ram air usless until 120 mph, Trans am's have ram air. Are these also usless till 120 mph. Im baffeled.

racerhex · 09-03-2003, 10:41 AM

Yeah but have you seen the setup up on a trans am its not the same! Plus V8's pull in more cfms any way!

Well, bumper is the best place to put the ram air, as it is the place where you have positive pressure, not vacuum. Ram air has alot to do with aerodynamics. Yes airplanes use ram air aswell, but its more on cooling issues. Why it wont help, well because at low speed the pressure front on the bumper is still too weak to provide any additional air pressure, that would "boost" the flow of your air into the engine, thats why.

BUT IT COSTS MONEY AND I WANNIT I WANNIT I WANNIT! Ok, Scratch that, money goes to suspension.

Actually, ram air should work at low speeds as well. I figure at lower speeds the air pressure is good enough to reduce resistance of the air being drawn in and at higher speeds it is high enough to force more in. Why I say this is because I changed up my air intake and I noticed a difference even driving normally. I dont think the idea behind ram air is to give the same pressure as a turbo or supercharger. This works fine for naturally aspirated cars too because of higher compression pistons...

Any thoughts??

Flashmn · 09-10-2003, 03:42 AM

I find that very hard to believe. It wont give you that much power that you would feel it. Hehe and you must be kidding, ofcourse it wont give you the same pressure levels as a turbo or supercharger gives

I think ram air is useless, but hey thats just me.

So are you saying NA cars with high compression pistons is better for ram air?

So this also means a Type R is better for ram air than say a 4 door civic with no vtec?

Ram air makes a difference that is noticible. I did it and some of my friends did it. If you take your air intake and funnel fresh air in, it is going to make a difference. I am telling you this from experience. Air is what the engine needs and the easier it gets it the better it performs. A better way of making ram air work also is to remove the air intake resonators on the intake and block the resulting holes. That way the air coming in is subjected to less turbulence. If ram air was useless, i dont think a company like TOM'S would make one.

An engine does not get air, it sucks in air a certain amount when the intake valves open and the piston goes down. The resulting vacuum will pull in a specified amount of air, regardless of the air filter. People have a misconception that air filters are also bad for performance, because they block air. Well har har, thats a big misconception. I would recommend you read few books instead of doing pointless experimentation in your backyard or reading import tuner. Haynes makes few excellent tuning books, which would make you see the big picture.
Tom's makes ram air also because of profits, people want to install them, so what better thing to do than to make a ram air and get some profits of it. Thats how businesses work.

IS200 · 09-11-2003, 06:07 PM

But the fact that an engine sucks air indicates that there is some sort of effort on the engine's part. Making that effort less will tranlate to more hp, however little. Just like polishing the intake ports, just like making the internals lighter, just like using a low resistance air filter therefore, just like having the air already travelling in the right direction before it even enters the the air intake. And another thing about ram air is that it uses fresh air which is cooler.
