As is mine: in on the 26th

Come on Wednesday

 

nope no bypass valve needed since the filter still is housed within the engine compartment and not in the bumper.

 

Thanks, This will be the first mod I do to my car after I get it.

 

hey what happen to the dyno

 

I like the Banshee wail !! When i get the SC which comes with the Icebox, i'll be disappointed to lose that sound.

 

Anil.

nice write-up... you will notice a big kick in the pants with the
headers as well.

 

Yup, i can't wait for it!

 

dy-no, dy-no, dy-no....

 

Ok guys, i did the dyno this afternoon,

Unfortunetly there were some issues that i totally forgot about that the guy i was talking to at SP-engineering brought up.

I don't have a scanner so i'll post my dyno charts tomorrow when i get them scanned.

But i will give you guys a breif summary as to what happened and what Ivan at sp-engineering mentioned to me.

Well my dyno before the install was (completely stock)
219.1hp, 203.8 ft-lbs torque

my dyno after the install was (icebox intake)
220.7hp, 203.1 ft-lbs torque

when he showed me i was like "what the phuck!" i spent 300 bucks on an intake that gave me no gain!

Actually what he told me happens is when the car is on dyno, it's hard to get good results sometimes especially when measuring intakes because what's happening is since the car isn't moving the amount of air that is normally being forced into the pipe isn't there. And even if they have a fan on it, which they did, it's not the same amount of air that would be forced in the pipe compared to driving let's say 60 or 70 mph.

That he said makes a big difference in the dyno. And when you see my dyno charts, you'll see what i mean. the graph of the run with the icebox is very speratic, and not smooth, it's very rough and jumpy as if something's not operating correctly. This was at the lower rpm end, this is the rpm range that i gained my peak hp with the stock intake.

Now, i'm not saying this to justify why my dyno proved to be the same as stock. But i guess i'll have to time my 1/4 mile runs and see how i do to really get a feel for the intake's true power.

But i can assure you, the comptech intake does do a good and very noticeable job in performance. So please dont let that deter you. Hopefully someone else that get's their car dyno'd with it may prove that it does do well.

Like i said, i will post the dyno charts tomorrow when i get them scanned.

 

so pretty much no gain

sorry to hear that

aem/injen cai still has an edge over comptech on this one!

I'm somewhat disappointed Never heard of the part about air movement being essential. Damn.


I suppose that makes sense though.

 

I'm a little disappointed as wel, but since i've had the opportunity to drive the car with the intake, i can be happy because i can feel the power gain. may not show on the dyno, but i know it's there.

when i've seen dyno's in the past, i've seen them use this huge fans on the car, and they put them in front of the car with the hood up, i always thought they did that to keep the car running cool, which may very well be the case, but today i learned it's also to get some air going into the intake just like it would be in real life.

 

take it with a grain of salt then. your real findings will be on the track/street. Keep us posted.

 

yea, i gotta make some time to head to the track and time my 1/4 miles, i've never done that b4 so that'll be a learning experience for me.

 

if youn feel like pioneering some more, go experiment with the aem cai and get a dyno i think that will be more interesting comparison.

That thought did cross my mind, i would like to try some different setups.

however i just bought my Zeal function-b6 coilover kit so u know where my money went, maybe after that i will consider it.

 

nice setup

R those numbers SAE, STD or Uncorrected?

 

If you're going through this much trouble to see the revs, the redline should be rotated to the vertical position ... top dead center. That's how it's done on cars in true race trim ... SCCA, WCR, F1, NASCAR, etc...

Uh oh. Your results are not encouraging. No power gain; no VTEC sound gain. Hmmm.

You should tell the Comptech dudes. Maybe they'll dyno you themselves to prove that their product does add something.

 

I think that guy messed up the Dyno. Even with the fan blowing you should see results. Maybe it wasn't setup right. I really can't believe a company like Comptech would make a product that didn't give any gains. Look at the ice box's for other cars. They do work, & have gains. Not saying if it's more or less the an AEM, but you should not see no gain. Call Comptech. Ask them how they dyno. Did you reset the ECU after installing? How many miles on your car? I'd drive it for a week or so, & then re-dyno. Maybe at a different place.

 

I like the fact that it looks stock.

 

Didn't Scalbert have a similarly home-made Ice Box that also failed to give any gains?

I find it hard to believe that the dyno was done wrong. I would guess that the environment (temp, etc) was similar as it was the same place within a few days.

I thought the ECU reset takes place within seconds or minutes (according to data that Scalbert has gathered).

I think your only option is to talk to Comptech and get a re-dyno, hopefully with their $$.

 

Well, I'm no mechanic, but let me see if I'm straight on this. You get little or no gain until you reach a high speed. I thought something like the Icebox would at least give a little more HP and torque. This is disappointing. This is very disappointing.

 

Yeah, I agree with Slimey. Call CompTech and review your results with them and see what they say. I'll bet alot of people who were going to get the Icebox will put it on hold until some better reports come thru. No one will want to spend over $300 bucks for nothing.

 

While air flow is a problem, it doesn't seem to prevent the AEM CAI from showing gains on the dyno. Hopefully others results will differ. I guess the Icebox' performance may be affected more by the air flow issue than the AEM because of its design.

 

Uh, what? Note:

That sure does look like a bypass valve on top.

Some correct me if I'm wrong, The purpose of the bypass valve is to save your engine should you submerge the end of the intake in water. It doesn't really matter where the filter is. The only reason the Icebox wouldn't need an intake valve is if the end of the intake is so high that the chance of submerging it is nil. And if it was that high it probably wouldn't be all that useful, imho.

 

where?
edit: I think you are looking at the flex joints.

 

I'm not canceling my order from 1 dyno, & 1 persons results. I'm getting a dyno next week stock, & then after the Ice box, & then after the headers go on. Stay tuned I'll post my results also.

 

I just sent the question on the bypass valve to Comptech.

 

OK, i'm an idiot, I'm looking at the flex joint.

I found this nice link tho:
http://216.239.57.100/search?q=cache...hl=en&ie=UTF-8

Good description of differences between the different intakes.

 

yea, this did cross my mind when i installed the tach. I just didn't do it. But i am considering changing it to that.

 

you will have the same results...

cancel your order and get the aem/injen cai

There was no mention of resetting the ECU in the instructions, and i didn't know how to do it. How do you do it? don't you just unplug the fuse going to the ecu, then plug it back in, and start up the car and push on the gas to get the ecu to remap the fuel curve?

driving it for a week or so i don't think would make a difference because like i said, i can feel the difference in power the intake has provided, i just dont' know why it didn't show on their dyno.

 

i am going to call up comptech and see what they have to say, and possibly get my car re-dyno'd at another shop. i'll keep you guys posted.

 

Ok, I just got off the phone with Comptech, and while i was on the phone, i realized something!

I was only looking at my peak power performance,

NOT PEAK PERFORMANCE GAIN!!!

Hold on to your pants cuz ur about to shit bricks!

I gained about 16 ft-lbs of torque at 3500 rpm
and i gained about 16 hp at 4500 rpm!!!!

i haven't had a chance to analyze the entire graph, but i'll do that soon, and you'll be able to see them for yourselves pretty soon too!!!

WOO HOO!!!!!!!!!

 

my dyno graphs are being scanned as we speak, so you'll see them soon!

i guess i scared everyone. so sorry, but i was being retarded when i read the graphs.

I had the AEM on the Auto I had. Yes I did get gains, but I got alot of noise. I hated it. That hiss, the vtec noise.... Some might like it. I didn't. Personal taste I guess.

You unplug the battery/pull the fuse for while. That should reset it. Also if you drive for a week, & didn't reset it, the compuiter will learn. Just takes longer.

 

That's good news. I can't wait to see the dyno graph.

:sighofrelief:

 

Based on his OBD-II data, Scalbert posted some time ago that the ECU is always 'relearning' and that the ECU is quite dynamic. I thought that he debunked the myth of disconnecting the battery or fuse.
