I'm sorry for this question as I'm sure it's been asked a million and one times, but I can't find anything in the search. I am looking to pickup a CAI and am wondering how much HP the intake will make without any other mods? I am expecting between 3 - 7 but that is just a rough ballpark. I know you can't really get any major gain until you replace your headers so please don't flame me on this one.

Thanks!!!

If I recal correctly... You will find a significant power "spike" at around 4500RPM but won't find much else where.

That is what I have gathered over the years of browsing this place. I don't have any direct impresions of this part.

 

I know people that have lost max hp on the dyno with an AEM CAI. But they say it preforms better at the track. CAI intakes are nitorious for the hump or spike in the dyno's.

 

I have heard that on a road course the AEM intake will hurt the engines dynamic response and therefore making throttle management more difficult in the corners and out of them. Ever wonder why you don't see racing teams using this piece?

 

Only thing I like about the AEM is the spike and sound. Everything else sucks powerwise.

 

Thanks guys!!! On another note, do any of you have pics of this past Thursday's meet, I couldn't make it. Edwin, you must, I know you have a camara with you @ all times. The meet at Kennedy HiFi, is it this week or next?

 

This week!

 

THis wasn't the best run of the day with the AEM. It made 164.x on a run but that file on my floppy is corrupt. Will get it later. I didn't bother to run a wide band O2 since I can't control my a/f but I suspect even with just the intake a VAFC might have cleaned some of this up and can help eliminate some of the spike.

Personally the AEM on our cars is underwelming while on a GSR an AEM or ICEMAN will make about 9-10 whp.

What system should we notice teams using on the track? And also what are the rules governing the high profile teams in the way of intake systems?

I thinkif I didn't already own my AEM and knowing what I know now I would definitely buy an Icebox. Good midrange from reports and clean looking.

I don't know if you are trying to be smart with this comment. So I'll just let it slide...

 

What do you think there's a loss in airflow dynamics with a CAI. I believe in factory airbox, but I want the noise, especially on the circuit. I dyno'd my car with the oem intake hose unattached from the airbox and it lost a good amount of hp throughout the powerband and nasty amounts of torque.

 

Hey...

I have been through the same questioning just recently and decided to go with a drop in filter. I haven't seen an AEM pick up more than about 5 hp in a Type R. I couldn't justify the pain of the AEM install for the little gain. I think the sound is unreal though, but I didn't want that in a daily driver either. I am no expert, but from what I have read, the icebox does seem to produce a little more than the AEM CAI all the way through apart from the AEM hump thingy. Hope that helps!

Good luck!

 

Wasn't being smart . . will reword.

Have you noticed teams using a specific system? Just curious what they are chosing and why.

 

It appears that most racing teams in North America use a system not that unlike the stock ITR setup.

For instance the realtime guys use the factory hose from the throttle body and direct it into an NSX airbox (like the stock box just alot bigger). They then bring air directly into the box through one of the headlights. Setups like this are the most common. The Comptech icebox is the closest thing to this that I have seen, and is probably why it apears to outperform the AEM in every way.

I believe it is the overall length of the AEM which is it's biggest draw back. There are large inductive losses through the intake plumbing while the engine tries to spin up. The stock system (and those like it) use the air in the box as a resivior which provides a short term air supply while the engine experiences short term loads.

 

what would the benfit of the larger airbox be? bigger filter allowing to pull more air?

So who does better on a highly tuned car? Say, cam gears, stock cams, JDM style (2.5") Header/Cat, exhaust, and Fuel control (Power FC, Hondata). Woudl the Icebox begin to restrict flow while the AEM would start to do better or the opposite?

I personally love the Icebox design just couldn't justify the cost of the Icebox to the cost of the AEM (Free)

 

What is this? Running on an ITR in (I think) the World Challenge series..

 

just a question......is the icebox the same for GSR and Type R?

 

FYI:

In 2000 the Motorola Cup ITRs (now grand-am cup) all ran the AEM CAI, including the King Motorsports entry. Not sure what kind of setup they have for 2002.

So, pro teams do/did run the AEM.

 

It only takes about a half hour.

 

If you got mad skillzzz...Took me about 1.5 hours. If you have done it before, I say from 45 min to 1 hour tops.

 

I think 30 minutes is a dcent estimate. I can do it in 20 minutes if I hustle. 30 minutes max.

It gets faster when you have done it a couple of times.

GSR's take an hour due to the stock airbox peices.

 

Thats what I was wondering. Obviously they're running it for a reason. It must be making them some power. I dont understand why though, unless like you said bigger filter = more airflow...

 

I've only seen King Motorsports Running the Mugen intake....

 

AEM is a real quick install.....amd also remember REALTIME has alot of dyno time and an airbox ideal for the rest of their setup....Like anything else if your car is modded differently it may like something else better.....

 

what would u choose the AEM cai or comptech icebox ?

 

Icebox
