ok, i'm sure there will be plenty flamers and "do a search" types, but i can't recall reading anything related to my question.
i'm wondering how the comptech ice box really differs from the stock setup. can't i create the ice box by:
-dropping in a k&n filter
-removing the resonator and related plumbing
-putting a little extension from the intake pipe that pulls cold air from the fender well (same as ice box)?
i've seen internal pictures of the ice box from aleph/d's s&m site, it's a bit more open and smoother. has anyone tried this?

 

Yeah, you can do a ghetto CAI ( i had one in my GS-R, it worked like a charm)....i probably would have done the same to the R, but the comptech looked like a much nicer unit than anything i could have come up with (for obvious reasons). Also, the smooth interior of the hose is going to be hard to emulate with any kind of flexible tubing...there may be no differece between ghetto CAI and comptech performance wise, but i did get gains with the Comptech across the board (particularly low and mid).

 

yea you can, what you just described is a $40 icebox, I am just gonna get it because I Like the having the fit and finsh of a refined product, even though I think a custom would make more power, because you can configure the piping to whatever specs you want to suit your needs

 

oh yeah, i remember, another factor was D saying "you're not allowed to modify your new R using any f0cking tape" That Frost King Metal Ducting Tape was on the GS-R after a year, sticking like hell to keep the intake hose held into the front grille...

 

hmmm, there is already a tube that extends from the stock airbox to the resonator. once the resonator is removed, we should only have to put a 3-4" extension on the end of the tube so it pulls air from the fenderwell. am i wrong? fit and finish should be pretty much stock.

 

I agree with Aleph with being able to emulate an intake, But I don't agree that it will produce the same gains. For all wanting a dyno chart Sorry, I don't have one.

And I am a firm believer that an intake, be it CAI or short ram DOES NOT PRODUCE HUGE GAINS like in a GSR or SE or LS or RS or Civic of any style for that matter.

I did the DIY intake by removing the resonator, and attaching Hd flexible Dryer hose with a horn at the end "YES with the stupid fugly tape!"

It felt like smoother throttle response but, there has got to be something with the more refined manufacture ," I know this will ge flamed" of the plastic molded piping that helps to maintain better torque and a livlier feeling all across the board. I did use a Foam Comptech filter with the DIY setup so filter flow wasn't an issue but maybe ease of airflow or lack of turbulance was the contributing factor to the Comptech's better feeling. Don'tcha wish I Had a dyno chart? I don't believe in those things anyway, unless they prove my theories correct!

I am pleased with my Comptech piece, my other choices were the Mugen intake but, "I 'm keeping the AC," or the ARC box but, "I just can't justify all that cash on an intake." Theres alot better ways to spend money on the R.

Oh and for the Pro AEM guys, I already had that one and I still opted for the Comptech...

oh, i'm not asking because of the icebox's cost. it just seems like removing the resonator would yield exactly what comptech is charging $250 for.

 

The Icebox itself is different from the stock airbox.

 

I toyed with the idea of just removing the interior baffle inside the resonator and runnig it almost stock. Like I said in the IM with just an intake on the R you won't notice staggering gains or differences. The intake is good but, a Header is where you'd unleash noticeable gains more than an intake.



It's a different setup GSR to ITR...

I've done the "ghetto CAI" using the stock air box. One thing I 'd like to add was that when I did it I removed the rubber bit from where the tube goes into the bottom of the air box, this made the opening significantly larger. I doubt it had much, if any, affect on power but it made me feel good

Yes, you can create your own "Icebox" CAI utilizing the stock airbox and fabricate your own intake tube extension. I have done this for about $10 and I have instructions which shows how to make your own, here is the link to my webpage: http://www.geocities.com/bretq/DIY_Icebox_CAI.html


Here is a picture of my DIY "Icebox" CAI opening with the turn signal removed.

How is the noise level of the DIY icebox? I hate the sound my AEM makes at idle, which is one of the things prompting me to change it (that and the filter is like 4 inches off the ground getting all dirty and wet).

 

icebox sounds little louder than stock and deeper at WOT

 

Here's mine:



I love it, seems to work great, butt dyno detects good midrange pull over stock. I'm running the stock filter too.

Ghetto racing ownz! Thanks for the good ideas/pics BSQ I've got some pics of my version in the link in my sig...but they're pretty much the same as BSQ's w/o the flared end. Still haven't gotten around to that part...

 

My DIY Icebox has a nice sound to it. At idle there is no differnce compared to stock. Personally, I like the sound of my DIY Icebox compared to the AEM. Now don't get me wrong, the AEM sounds nice at WOT, but I personally like the sound of the Icebox better at WOT. Also, there is no whistling sound, which the AEM has.

 

Since the intake piping is not "relatively" close to any heat, there should not be a concern. Someone a few month ago addressed this issue and stated that PVC doesn't start to off-gas until around 250 degrees. Also the piping is constantly pulling is "fresh cool" air so the piping should stay cool. I plan on running some temperature test this spring-summer and this is one of the things that I would like to test (ie. the temperature of the tubing at idle and at speed).

One other thing that I need to look into is whether the thin-walled tubing which I used is truely PVC or if it is some other material. The reason that I question whether it is PVC is because PVC is normally rigid and the tubing that I used is not rigid (ie. it has some give to it).
