Comptech ButtDyno. -.^''
Ok, I got a 98 ITR with Mugen 4-1 Header, Mugen Twinloop Catback, High Flow Cat, AEM Pulleys, MSD 6AL, MSD Blaster Coil, Nology Wires, and a recently added Comptech Icebox.
Now for the issue... I used to have an AEM CAI installed on the car... Everytime I hit VTEC the car would roar and you'd feel a small jolt and a nice pull all the way to Redline. Even though the Filter was Extremely dirty.
Ok, now ever since I installed the Comptech Icebox and Arm... It's been quite different. When I hit VTEC, the sound of the engine barely gets any louder, no jolt, and what seems to be a weaker pull. Why is that?
- Is it that the filter is dirty?
- Is it that it's not getting enough because of the angle of the opening in the fender?
- Or is it just because the AEM CAI was a better intake?
I'm gonna try taking the cover of the Icebox off and driving it tomorrow to see if it's the lack of air effecting it... Hopefully I can get this issue resolved...
Anyways, Thanks. And some suggestions/help would be nice.

yup

Exactly. With the AEM CAI, the power was more on top. With the Comptech, you get more bottom and midrange than top end. I did the exact thing you did and I will never go AEM again.

Actually a typical dyno of the AEM will only show gains at VTEC engagement due to Helmholtz (sp?) resonance. By design longer tube intakes like the AEM tend to die off in the upper range.
Comptech is quieter and has a smooter torque delivery (flater, less spikes)

So with the Comptech I'm getting more Low-Midrange power than High-End? Is that a good thing?
Wouldn't I want more High-End power since the RPMs tend to stay at 5500+ while racing? Or do you mean like 7000+ by "High-End"...
Thanks.

Mid would be like 4-6
I also switched from aem to icebox and would not trade for anything less than mugen. AEM attracts too much attention and does not have a smoothe power curve. You want the motor to make smoothe power, not spikes here and there. The car will be more predictable when racing if it has a smoothe curve.

Still rocking the AEM personally

agreed, i run a comptech icebox with a apexi power filter stuffed inside, attached to a stock ITR arm. it helped me get these smooth *** curves

It depends on what you want really.
The Comptech allows for better throttle response and doesn't create that "AEM Spike" which can even drop below the Comptech's gain after said hump but will make up for it partially at the extreme top end 8200-8400 redline.
I specifically chose the Comptech because I wanted better results in the middle where the R is anemic and wanted quicker/better throttle response. I chose a weak point of the R's powerband and used an intake that would hopefully help in that area.
Top end is top end but if you aren't using it constantly then you may not be fully utilizing the gains. Road Racing and or HPDE's and Autocross are Not only about top end but alot of the middle of your power and torque curves up to the top. On a track, you're constantly shifting gears and traveling from your midrange to your top end as you wring out each gear. You don't instantly jump from 8K rpm in one gear to 8K in the next.
The Comtpech and AEM both have advantages and gains that the other does not.
I too went from the AEM to the Comptech and for several reasons am alot happier with the Comptech.
Unfortunately it sounds like you didn't do a heck of a lot of research before switching products.
An intake on the R is not magical as on other Tegs.

Agreed, there is no magical intake for the ITR (although I think most would sport a mugen if they could). But I still don't get why people believe that the AEM is king of the top end. Of course every car is different, but, by design a short ram intake owns the AEM on the top end.

I have the Comptech IceBox and High flow intake on my JRSC Type R, and with the top cover in place I can't even hear the supercharger whine. I'm really impressed with how smooth it is, quiet too. When I bought the car it had some POS cold air intake which make a crap load of noise on VTEC, which did make it "feel" fast, but I doubt it had anymore power than stock.
Alright, well thanks for all the help. I guess that's just how the intake is supposed to be... Just didn't really think much about low-mid range power at first... I guess it is more practical for daily driving anyways. I don't really race often either.
Kinda off topic now... But... Has anyone ever tried riggin up some kind of "Ram-Air" type of thing from the front bumper to the opening of the Icebox? Or is there already sufficent air leading to the opening?
Anyways, Thanks again.
PS. I need to freakin dyno my car... -.-''
