so my idea would work? using the radiator reserve.. just filling it with liquid nitrogen.. and continously runnning a cycle?
liquid nitrogen is an AWSOME idea...but its too rediculous. buying, storing, and carefuly containing liquid itrogen just isntsafe or feasable. thats why i thought freon..or water would be better. freon isnt exactly great for you or the environment...but it doesnt aumatically kill all your skin on contaact. and its easier to get and store
Hey turfnnsurf, I had the exact same idea for an intake as ur setup there. Now i know it works:D. Except i'm using 2-1/2" aluminized muffler pipe:(.
AvgWhtMale, man, if you know about fluid mechanics, and you wanna say a bit about 'em, plz do so!
And how come I haven't seen anyone mention the handy little formula, "PV=nRT"? I used it to do some calculations, and figured out that if you go from 30 Celcius to 5 Celcius (sorry american dudes), ur getting a 9% increase in air molecules. Something to think about.......
PV = nRT! P = rmg + 1/2 mv^2! It's all good. That pressure diagram is wicked cool. But I think it's just pressure, not pressure gradient. A pressure gradient is the change in pressure in a given direction. It's dp/dx, for the mathematically savvy. This picture shows the pressure on the car's body, probably down the centerline, relative to atmospheric pressure. You gotta know that pressure is inversely proportional to airspeed (what is the latent airspeed velocity of a laden swallow?). Therefore, the higher the pressure, the lower the airspeed. So the air hitting the front of the car is at very high pressure cuz it's being slammed into by the front of the car. It ain't going nowhere. The air on the forward half of the hood is like, "hey, check it out, we can go over the car if we go this way! Wohoo!" Then it hits the windshield and it's all, "Bummer, dude." Hence the high pressure against the cowl. Then it gets to the top of the windshield and it takes off like a mo fo. This is where the car thinks it's a wing and generates some lift. If the car were going fast enough, it would actually fly! Well, not really. But this is the reason that cars have spoilers- to "spoil" the airflow and make it go turbulent, thus slowing down the air and increasing pressure, thus cancelling lift. Wicked.
As far as CAI, it works because colder air is more dense, and therefore contains more oxygen. More power per cubic cubelike-thingy, more bang for the buck. Free horsepower! Yippeee!!!!!!
Free because usually you have to give up something to get something -- low-end torque for high-end power, fuel economy for speed, etc.
Me like free horsepower.

Well as soon as I find a sheet of aluminum large enough... the hood scoop will be extended right to the front of the car... it will even over lap the front of the hood slightly... you'll see when I'm done.
If you place the scoop back where I have mine it has to be 3" or taller to get a lot of air to go in... I think my most recent scoop is 1.5" at most. I realy wanted to get a Subaru WRC scoop but they are much too curvy... so angled aluminum it was.
Hey avgwhtmale, show us how that "P=rmg+1/2mv^2" formula works:tongue::flash:.

Ok this may so9und dumb but.... if you take the stock airbox from say like a newer civic (where the filter rests) and stick the correct filter into the top of the box with the 2.5 -3.0 inch outlet..
connect that to the front bumper grill and run some tubing to the carb with a mod'd 91 civic pgm-fi box on the carb.. wouldnt that work for a small version of the front air intake??
correct me if im wrong or tell me if you dont get it im not very technical...

That formula looks like an equation for energy balance (P is in energy units at least). m is mass, v is velocity, g is the gravitational constant (9.8 m/s) and r is the height above or below some reference.Quote:

Alright I have been making pieces of this box for the last hour. And yes safety is #1 now. After getting hit in the eye with hot plexi-glass spun up by the dremel. I washed my eye out for 5 minutes and I was looking around and finally got the little piece of plexi-glass out. I can see ok now but my eye freaken hurts. But anyways back to the ram air box I'm making. I can't draw on here so what I'll do is just draw it on paper and scan it and hopefully someone will host the image for me.
Can someone please host my image that I drew up? I just have to cut one more piece of plex-glass and I will just have to assmeble it and put the hardware on and weather stripping.
arent you wearing glasses of some sort, safety glasses? Its important when you are grinding anything, esp with a dremel tool to have protection
Oh yea i also forgot to mention, downgrade engines like D16 have much much weaker engine internals, like cranks, rods pistons (compared to b16) ... even tho the blocks are close
Dude I think you got the wrong thread :DQuote:

88 Accord DX check your email. Those pics were when I didn't quite have everything measured up and cut out. I have everything cut out I just need to assemble it and get some more hardware from the store.

hehe probably had multiple windows open... I do that a lot and have to cut and paste... then delete the response.
Oh and I do have safety glasses somewhere I just can't find them. It's also good to wear safety glasses under the car b/c when I installed my headers I got rust in my eye.
Does anyone else want to host the pic b/c I guess he isn't online now. It's JPG form and 32kb.
hey chill out i was talking on AIM. anyway here it is:

yeah... sorry
Dude I was just saying you were offline (not on 3geez) Don't take shit personal. Thanks for hosting it by the way.
Alright, I finished the ram air box construction. Now all I have to do is put the weather stipping on the top and around the intake hole. I wasn't expecting it to turn out this nice. I'm thinking about slapping a K&N sticker on it just to kinda make it not so clear. This is what I used to make this project: sheet of 1/8" plexi-glass, weather stripping, silicone, 12 L brackets, 2 hook and staple, 30 self tapping screws, dremel, time, patience. The reason I didn't expect it to turn out nice is b/c I didn't know some measurements and when I had everything cut out it didn't seem to match up perfect. There are some small 1/16" gaps in places but I'm putting silicone on the edges to seal everything up. Now I just gotta paint my hood scoop and put a screen in it and cut a hole in the hood and glue the mofo on.
you gonna have to take a picture of it.
Alright I just measured out the weather stripping. Hopefully people will want to do this same thing that I'm doing. If it works the way I designed it you won't have to remove the battery at all. I have to do some more construction still I forgot the hinges for the bottom. It's hard to explain but it will fold and close around the intake pipe and then it will lock on with the hook and staple. I'll take pictures when it's all finished.
