Deading the Sound of a CAI? Can it be done?

[Suntzu]

I have the fujita CAI. Its a really nice afffordable CAI but im starting to find the sucking noise at WOT as unacceptable in my capacity as a stealthmobile driver.

I like the performance but not the noise.

I was toying with the idea of using sound deading in that small compartment where the pod sits, you know where the big ass resonator used to live before I evicted it.

I am considering using FLASHTAC or DYNOMAT but i dont know much about the products or how effective they would be when stuck to the walls of the compartment.

Im interested in comments or suggestions about the viability of this project.

cheers

I think it will still be loud. Why don't you try the Icebox? It is cheap and i doubt you will notice any negative performance difference.

[Pumped]

I dont think sound deadening on the inside of the bar will have any change at all, adding some weight to the actual intake might lesson resonance but its the pod thats ultimately going to be making the noise; you wont really overcome the loud noise of a pod without removing it :p

I 2nd. that!That's the main reason i got the Icebox.I teamed it up with a K&N filter.Noticeable gain and hardly louder than stock.Cost me $280 delivered to my door.:thumbsup:

[enkay]

what if you do one of those ghetto intake boxes and put some sound deadning material in there haha =P
just a thought no idea if it would work haha

If you can convert it to a SRI and make up an intake box it'd work.Contact Aaron,he's the ghetto specialist!:p

[tron07]

I couldnt stand those sucking noise either....

If you want quiet then you'll want a resonator box, which really means you want a stock induction.

[Limbo]

just box the filter, legal and will quieten abit.

Otherwise go stock box with panel filter

Is the K&N filter much quieter than the stock one that comes with the Icebox (I think it's the Unifilter one?)?

Is that the setup that requires a seal on the box also?

Don't know,i haven't run it with the Unifilter.I ran the K&N filter with the stock intake and the noise increase was next to nothing. With the Icebox you do need the seal if you run the K&N.

russell,

you want to deaden noise because you think it attracts too much attention at WOT correct? why dont you just not use WOT? i only ever WOT when im driving it hard, and whether the car is making noise or not, its still attracting attention...

in relation to your question about sound deadening, shielding it will make it slightly quieter, but the only way to cut make induction noise is with resonance chambers and piping... hence why the stock system uses sush a long intake tract... you could make up a custom intake that uses larger pipung, but still runs via large intake chambers, this would keep the noise down without restricting any air...

The icebox has no resonator and it sounds only slightly louder than stock even at WOT.

the icebox itself acts as a resonance chamber... although i was refering more to deadening the noise on a pod filter...

ive done some work on mates intakes, had one setup that basically kept all the stock piping, but took out the panel filter (so it became a straight thru the stock filtration system) and fitted a pod to the bottom of the stock piping... kept very close to stock sound :D

[tony1234]

Again i don't think you can go past the Icebox for all round performance and quietness.

[akina]

wow, all i remembered was when u first got the intake and how much u were loving the sound... lol u were like posting it everywhere

[Spoon-Accord]

true true, i love induction noise,
some people don't

just slap in the stocker and put in a panel filter,
saves the trouble and the music to your ears :)

Icebox is a good alternative. Better power and throttle response with a bit of a growl (not super loud like a CAI).

Agreed.Get an Icebox,pull the CAI off and put it up for sale here.

[Suntzu]

Copy that. I will do that.

I use WOT a bit cause im a revhead.

Can anyone here say that they have heard both the Fujita/Injen/Jtune style versus the Comptech in the flash? Is there that much real world?

Now Im thinking stock airbox with KN filter ( all the plumbing resonator removed) might be just as good as th ice box???

I'm running exactly that stock airbox no resonator, K&N filter. Only noise difference from stock is from 3500-4500rpm in 2nd and 3rd gear very throaty sound. Performance wise its an increase, but I can't say its massive.. its just a filter.... Looks cooler though... got a K&n sticker with the filter for the airbox

Stock airbox with the K&N filter will not outperform the Icebox for 2 reasons - It doesn't have a velocity stack and the airbox on the Icebox is bigger with a smoother surface. Removing the resonator alone will also cause some unwanted vibrations are certain RPM ranges.

I've heard pretty much all the intakes out there: Jtune, Injen, K&N, Icebox, Mugen, Gruppe M etc. The pod style filters are A LOT noisier when you give it some stick (esp when they are in SRI mode). In terms of power, the pod filters make a tiny bit more power near redline compared to the airbox setup but at the same time they aren't as responsive & have as much power down low. In the real world, the airbox set up is definitely better imo.

[johnprocter]

lol this may sound like a noob question but whats WOT and how much you looking to sell the CAI for mate?

[akina]

wide open throttle

[johnprocter]

what the hells that LOL

[akina]

when u plant ur foot down on the accelerator/flooring it.

[johnprocter]

oh right thank you good sir :D

[Suntzu]

I did like the sound intitially but after a while its starting to wear me down. A lot. Also I dont want any attention from the man in blue. Im so unlucky/stupind that im likely to give it some stick near a unmarked car or something.

looks like theres a few Comptech iceboxes on ebay usa, but with comptech shut are they genuine? i also hear the icebox filter is crap and the KN doesnt fit properly??

[enkay]

nah i think comptech is under new management (correct me if im wrong), so i think the iceboxes should be genuine but not 100% sure since there could be fakes out there haha

I got an Icebox approx.1 mth.ago,$270 shipped.:thumbsup:

Pod filters give approximately twice the flow rate to that of a panel filter...

wtf u buy an intake for if u dont like induction noise?

its like buying a tennis racquet and hating tennis.........

[Suntzu]

Sorry your highness but given that Ive never had one/nor heard one in a euro before how the FK would I know how loud it would be? Not all of us are wannabe rice boys.

I love the sound, i hate the volume.

Justin: Good point about Pod vs Panel. Then agains it depends on how much air your engine needs as you could double the potenttial volume going in but if it only needs another 10% more than stock are then double the potential volume is hardly a gain.

[johnprocter]

kazam your a madman

[henri123]

kazam your a madman

madness.. ? MADNESS ? ???!?!?!?

[kazam]

shouldah dun your research brah, intake = 95% induction noise, 5% performance variation... regardless of car, and please call me kazam.

[Suntzu]

Sorry but an internet forum wont give you any idea about sound pressure and noise at 6000 rpm.

[kazam]

first of all u have CAI which has less induction noise than SRI, so if u had dun a bit of a search u wouldah realised that intakes have induction noise... wat did u expect wen u bought an intake?

[Suntzu]

Kaza,

your logic is so retarded all i can say is

Dont Say Another Word! :zip:

[kazam]

lol yeh alryt bro, u bought an intake but dont like induction noise. been on the forum for 2.5 years and u dont like using the search key... 1 simple search wouldah gotten u enough results to conclude that INTAKES have INDUCTION noise.... good 1 mate. next thing you no, you'll get a wife and realise u like guys.

[94dc2tegz]

^^^ Lol!

i had a cold air intake on my pulsar (SR20)... with k&n pod filter... it made no where near the amount of noise the cai on my euro does! it was practically silent compared to this one! so in suntzus defence, unless someone had posted a video on here of the intake (which they hadnt!) how would he have known? he couldnt have...

he's not blaming anyone for this, he's just asking for advice, so try help him out, thats what we're all here for! :D

and russell, yeah im with you on that one, just because a pod can deliver two times the flow, doesnt mean your engine needs all that flow! when it comes down to it, the exhaust and intake manifold/tb itself can only let so much air thru... its like building a 3lane bridge that goes to a 1lane road....

:D

[Suntzu]

I used some dynamat type material and it didnt do shit except mate the resonator air feed area cooler due insulation from engine bay and foil reflective goodness.

Then i put some lumpy/wavy style sound proof foam i got in there and it was heaps quiter up to 80% throttle but then the elephant gets out and rampages around my neigbourhood.

Kind of experimenting for fun!
