Does anyone happen to have some photos (or a detailed diagram) showing all of the parts of the air box system; that is, the air box itself and all of the passageways through which incoming air travels?

The photos I found in my manuals only show what the naked eye can see by looking into the engine compartment. Not very helpful considering how many things obscure the view.

I have an idea for modding the air box, and need to be able to visualize it from all angles (without removing it, of course).

 

Air only travels one way from one location with the stock airbox.

 

just remove it, takes about 5min maximum

 

you gotta be kidding... is just the AIR BOX for christ sake ... if you can type on the keyboard and make a new thread then you can remove the whole thing...is...just as EASY.

 

I don't want to see the actual air box by itself -- I know how to remove it. What I want to see is a structural and functional representation of the AIR FLOW through it as a part of the ENTIRE air intake system so that I can determine air pressure at various points throughout, including the things to which it attaches, like the MAF.

Listen, a monkey with a drill can punch random holes in the bottom of the box. That is not what I want to do here, either.

I can see now that I came to the wrong place.

 

I don't think air gets "pressurized" in the airbox. I'd think the pressure would be pretty much the same throughout the entire assembly.

 

pressure in the intake is going to = atmospheric pressure, unless its forced induction.

 

youre trying to turn something simple into something complicated. and air intake is ridiculously simple. you dont need to visualize all the angles and calculate air pressure at various points. the pressure will be the same throughout the whole intake, and thats gonna be either atmospheric pressure, or slightly below due to the vacuum the engine causes. dont try to convert a garden hose into a jet engine here, just keep it as simple as it always will be.

 

I don't have a diagram, but i want to wish you best of luck on your project. You have the right idea about trying things out and seeing if they work. That's what being a car person is all about.
Good luck to you.

 

Thanks for the words of encouragement. Apparently, you are in the minority here.

But, that is OK. They laughed at Noah, too.

Actually, Xugg, forced air induction is part of it.

So long, and thanks for all the fish.

 

Hey, I would like to see a diagram as well. Why? Well, when i bought my car there was no check engine light on. However, when i use the ODD II reader, I get a knock sensor code, an EVAP sensor code, and the O2 sensors are both bad. I would like to see how the EVAP looks like since I don't seem to have one. My Intake temp sensor was bad but I modded a 95's ITS so it's off now. Where is the EVAP and how would i replace one?

 

Optimium intake design will be a compromise due to space limitations. I doubt what you have in mind is different that was has been tried but good luck anyway. OSCI has been done, hacked stock box, cai, hai, hai with scoop, sc,turbo, turbo with nos, sc with nos, na with nos, etc.....

 

Ufff.... *dry sweat from forehead*.. .for one second i thought that comment was about me.... i was getting ready for action... lol

 

iTS JUST A PLASTIC BOX.

 

You're not a dolphin, and the world's not ending.
:-D

 

UPDATE:

I saw an article on an Australian website where the testers built a low-cost device (around $20) using an adjustable, air-actuated switch that can be activated by as little as .01 PSI! The DIY device consists of the switch wired to a higher voltage relay which would then activate a buzzer or light when tripped. The intake of the small switch is connected to a length of hose, and the end of the hose can be placed anywhere one wishes to check air pressure.

For example, you could place it in your air box (or intake tube) and use it to tell you when your air filter needs to be cleaned or changed...or, in the example used in the article, find the best place to locate the opening of a CAI.

So, I am going to build one and experiment with making changes to my existing stock setup. I have three goals in mind: increase air flow over the stock setup (stock airbox with K&N filter), keep noise level as close to stock as possible, and lastly, prevent any water from getting sucked into the system.

Even if it has all been done before, the learning experience is worth the effort involved.

 

Nothing wrong in trying. Best of luck.

 

A different intake design won't show much gains. Intake manifold design has much more to do with an engine's VE than an intake system ever will. And i doubt you could improve on the stock intake resonator's design. I applaud your pioneering spirit though.

 

Thanks for the applause. I have two questions, though:

1. Besides reducing noise, what else does the resonator do? I am referring to the one that is right below the stock intake and branches off from it? What would happen if just that resonator was removed?

2. I want to send more air to the TB than the stock system does. What parameter changes over stock would you consider to be an improvement? For example, how much of a change in PSI does a typical pop charger generate over stock, and would you consider that change to be beneficial?

 

Hmmm, I think a pop charger will produce more PSI but less air density due to the difference in air temperature it is pulling in over stock. But the stock air system may allow the air to be heated as it flows through and around the engine anyway...

 

There have been dynos of running with and without an air filter and there were no appreciable gains. The filter is NOT the bottleneck. The only intakes that are worthwhile are the ones that go into the fender. They worthwhile not because they pull more air necessarily, but because the air is cooler.

 

And cooler air is denser, meaning it takes up less space, or conversely produces less pressure in a fixed volume. When the volume is fixed and air temperaure is also constant, then the only other way of increasing air density is to raise the air pressure without raising air temperature.

That is exactly why a ram air system can produce a comparable result to that of a CAI system.

We already know that CAI's are easier to put in a car like the Maxima than a true ram air system. That does not mean that a ram air effect cannot be created for it without resorting to superchargers or putting on hood scoops.
