Ok so I hear alot of debate between a short ram intake and the Icebox, so my idea, why not buy the Comptech short ram intake, and the ice box, and use both, but leave the lid off the icebox? This way, cooler air is still being sent to the filter, but the top is not on the icebox to restrict the amount of air you get. Has anyone tried this, and if so, what were the results?

 

hhavent tried it but sounds good to me

 

I did this when I had my ice box and comptech short ram. I could not find the post, but I think someone lost a little horsepower with the lid off, however he mentioned (and I agree) there was excellent throttle response, and he could barely feel the difference with the lid off. You deffinately would have the best of both worlds. I would definately go for it!

 

I am sure that the maximum HP would not be there, becasue the closed lid on the box creates a vaccum I assume, to actually suck cold air in, my thought thought is that if there is already a little bit of cold air flowing, and the lid is off, you should have good throttle response, little risk of hydrolocking, and some cool air headed towards the filter. Perhaps depending on whether or not the snorkel could be modified, or make a piece running from the front grill to the mouth of the snorkel, to help more cooler air head up would be a decent set-up I believe. I will def try this, and this has made me decide not to get the J's intake.

 

if it was meant to work best that way..comptech would have made it that way..

 

Cooler air is NOT being sent to the filter. Here's the deal: nature follows the course of least resistance (a statement of conservation of energy). It takes more energy to draw air up through that long, relatively narrow tube than it does through the open top of the box. Proportionally, drawing only a tiny fraction of the volume of air from the "fresh" air source, entirely negating any benefit to having bought the Icebox in the first place.

That's my beef, too, with people who take a piece of dryer hose and "aim" it at a short-ram filter. It's basically wishful thinking that the air outside, with a random momentum, is going to find its way into the tube, through a torturous path, into the filter.

 

The law of conservation of energy states that energy can neither be created nor destroyed, I am failing to see the connection with the movement of airflow.

I know that there will only be some cold air traveling up that tube, but again you have to understand what I was going for here, not a CAI, but the throttle response of a short ram along with the fact that some cooler air would flow from the outside up the snorkel to the filter.

I do not know if this would be beneficial or not, that is why I tossed the idea onto H-T. Just trying to get some thoughts and see if anyone has done. I do appreciate your post, and yes you are right about the whole idea of not getting alot of cool air into the filter. I don't own the icebox, and don't know where the snorkel ends. So I do not know whether it relies on air being forced into it, or sucked through it.

 

I've always pondered about the same idea. Although, perhaps for an efficient setup, you would need to route the snorkel's opposite end against the air flow as if your intentions are to "force air" into it. Air would then travel up the snorkel and directly to your short ram. However, wouldn't that create more drag since all that air is being thrown around into your engine bay?

NRG

 

This is actually the idea of "ram air", and it's part of why F1 and IRL cars, to name a couple, have forward-looking air intakes, despite the drag penalty. Really, with Integras, drag would be kind of a small penalty, since the car (especially the underbody) is so dirty anyway. The thing is, though, that to take advantage of the effect, you'd want smooth piping without twists and turns. Two right angles (like up and back, for example) would introduce enough of a pressure drop to kill the whole thing. Ideally, I guess, you'd plumb some smooth-bore tubing directly from where the passenger-side headlight sits now.

 

As has already been said in this thread, it is there for a reason.

It keeps warm air from the engine bay, out of your intake. I personally would not mess with an intake design that makes these kind of numbers - Yes, that is the same power as the Mugen intake.

I am pretty sure that the R&D departments at Comptech and Mugen know a little bit more about intake theory, and how to make power, than Joe Sixpack on Honda-Tech.

 

I did this with my stock intake, just replaced it with a hacked version of the stock filter with a K&N installed.

worked out great.

really cheap too.

forgot to say that I ran without the cover on the stock box.

Correct: conservation of energy states that energy can neither be created or destroyed. If you fail to see the connection with the movement of air, then you are clearly missing some thermodynamics (or perhaps some fluid mechanics?)

The "course of least resistance", in thermodynamic terms, means that in the absence of external work, any system follows the minimum-energy path. For example, less work is done by fluid travelling through a small pressure gradient (i.e., the open lid) than a large pressure gradient (a long tube with curves). So, air "prefers" to travel across the open-lid boundary. than up through the tube. IT would take MORE THAN THE MINIMUM AMOUNT OF ENERGY for the air to take another route, and since we are not creating energy here, conservation of energy requires that the lowest-resistance route be taken.

Sorry for the thermo lesson, but you seemed interested. I'm starting to feel like a T/A again!

 

Man I love sience, now fluid mechanics, that is what I am talking about, I can't wait to take my physics coruses next fall in college. That was good link to the whole conservation of energy thing, and after your first post, if ifgured you would have made a better connection with thermodynamcis, this forum is great!

I know comptech has done the research, and I will say this again, I am not interested in Max numbers, just a good compromise between throttle response and Hp, so I was TOYING with this idea. VTechie understands what I am trying to establish here.

VTechie, I noticed that the snorkel on ice box is relatively small, lets say we could find maybe a 2.5 inch pipe with mandrel bends that would act as a "ram air", do you think this massive amount of air being forced up iat the filter would have enough energy to work its way into the filter and into the engine? This may be an idle set up, but the problem is, where to draw the air from. Trying to do it with minimal turns would reallly be hard.

 

I personally would not mess with an intake design that makes these kind of numbers - Yes, that is the same power as the Mugen intake.

Numbers don't lie, I say leave the box on. I have actually tried running the Icebox with the lid off on both an LS and ITR....it made the LS extremely loud, but almost sluggish...and the ITR..nothing seemed to have changed, not even the sound.

I was about to say.... lol

However the Mugen makes a some good midrange power, though. But **** spending 600 dollars and waiting 3 months for that.

 

Yea the Mugen never was and won't be an option. I just like toying with things to make them better, that is why I bought a Teg I am dying to get back to Chapel Hill and get back to work, so I can get some $$ to start the modifications!

 

OMG ! your joking right ?

if you take the top of the airbox off where does the airflow come from ?

the same underhood high temp crap the box was designed to isolate

Buy a intake tube, an NSX stock airbox and a K&N drop in filter. bolt it up and where to get the coldest air from should be painfully obvious.

 

Good luck in college next fall. Physics is a blast.

In answer to your question, I think it might be possible, under certain conditions. The bend would have to be really shallow, and you wouldn't want consecutive bends (like I said, one that goes up and then one that goes over would set up a lot of vorticity). A lot would also depend on the inlet design. You'd want something that looks directly into the airstream, and preferably one should have as big an area as possible to have a high inlet pressure. Imagine a trumpet horn, if you will.

Like I said, good luck in college. This will be one of my last posts on this board, my GS-R was stolen last night. Had her since 1997, my first new car.

That blows, so much... I am sorry to hear that. You are done with Hondas and your buddies at Honda-Tech forever?

Sorry to get all OT.

 

Maybe not. My wife has me thinking about an S2000, so maybe I'll be back...

Anyway, I started a topic on this.

Thanks for the sympathy, though!

 

Damn Vtechie, that sucks the big one, I am always worried about my teg after reading that someone had their car stolen, damn stupid thieves.

Ninja Kitty, why in the world would I pay for an NSX airbox? The Acura legend air box is almost identical, esp size wise, and can be had at a junk yard for a few dollars. If I wanted to build my own intake I would, but its not thay big a deal, as I have said like 10000 times, I am toying with notions and thoughts. Why post if you are not interested in the idea?

It kills me when people just dismiss an idea with little thought, or in this case, not understand whats being discussed hear. I did not say I wanted a CAI, but a short ram possible benefitting from some fresh air coming in.
