So I just removed the resonator and I love the sound at high RPM, but I hate the low rpm hum. I think I have a solution for that though. I think if I cut off the Longer resonator tube ( and plug the hole) and leave the short one I will get rid of the idle hum. I will try it tonight I think.

nah im saying... if i remove the bottom 1/2 resonator will. my shjort ram be louder? and im pretty sure it will be much cooler

ou sig

oh I see...your short ram will sound the same...BTW how do you like the sound?, but you may get some more fresh air up to it, so I would take the bottom intake resonator off

alright guys, i jsut took my car for a spin and after flooring it this time, i noticed the hum at idle, but it wasnt there before. im guessing that it really neads to be sealed or somethin.

ou sig

who knows, at least it was real cheep and we can always put the stock resonator back in to get rid of the hum if we need too.

so when you had the stock one on and had it taped shut, did you have any hum? I dont think the tape would ever be a problem, I may just do that, so I can get the extra sound

dark inspire

i never really took it out, i just taped it up. this is the first time i noticed the hum though, so im gonna open it back up and see if WOT did any damage to the tape. Stay tuned...

ou sig

ya I think we need that stock thing there to get rid of the hum

i dont understand why? the cai's and short rams dont have hum, it has to be something in the piping causing it????

ou sig

thats what I was saying earlier...the aftermarket intakes are metal...but the Icebox - is that plastic? damn I dont know. I was thinking because the stock intake is thin plastic maybe it absorbs the engine hum more than the metal ones. or maybe the aftermarket ones dont have that hole, so the sound is sent down to the air filter...

dark inspire

yeah i think we are on the right track here, the icebox is plastic, and all the other CAI's are "filters on a stick". hmmmm maybe the rubber piping resonates too much, u would thikn the opposite of rubber wouldnt u? interesting....

I think it's just the sound of the engine. There are actually two resonators there, a long one (for low pitched sounds) and a short one (for high pitched sounds like the idle hum). Tomorrow I'm going to try eliminating the long tube on the resonator and leaving the short one intact. Hopefully I'll get the nice WOT sound without the hum.

The TL type S does not have that upper resornator becuase i just went to check mines out. I think they are only on the TL-P.

interesting...

A hockey puck fits perfectly in the resonator hole. I have found that since is solid rubber you can tighten it better and because it is solid I do not have any unwanted sounds. Besides, now the NHL is on strike hockey pucks are available!

lizard

I used a hockey puck for the upper resonator. I like the fact that I can tighten the hose clamp to something solid so I do not have to worry about leaks. I have not noticed any unwanted sounds. With the NHL on strike there are lots of pucks out there!

After some testing I realized that the longer of the two tubes in the resonator is the one responsible for removing the hum. This is the complete opposite of what I thought to be true, but I'm no expert on noise cancelation. I cut the end off the shorter resonator, and cut the short one off near the top of the unit. Then I epoxied the end back onto the resonator to plug the hole. The car is quieter than if I had removed the resonator all together, but the sound is nice. I would say it's right inbetween if you had the unit in and if you had it out.

fsttyms1

its not. remove teh intake pipe and start the car with out it. it doesnt hum

blackonblack02

I just tried it and you are correct! I think The hum may be a function of the distance between the throttle body and the air filter. That may be why the aftermarket CAI's don't do this. Another theory is the hum comes from the air moving over the space in the tube. Similar to a person blowing over a coke bottle. That may be why the hockey puck trick didn't have the hum.

whoaaaa cool. so umm, how much do hocky pucks go for.. and do i use the standard size? like the pro ones or something? i dont know anything about hockey, so can i buy it at like modells or sports authority?

and also, when i stick the hockey puck in, wouldnt it just slip into the hole all the way?

fsttyms1

think it has something to do with the ripples in the rubber tubing and the rubber itself. this week when i get a chance im going to try a few things out to see if it helps( ive got a few ideas). ill keep you posted.

subtledreamer

haha yeah i would like to know if there is any specific size we should use, as i know nothing about hockey at all too.

and to answer your question about how it might pop in all the way... i believe that it wouldn't if you tighten the metal clamp hard enough.

btw i think this thread is just uber cool. it's kinda rare nowadays to get a thread on something entirely fresh!

dark inspire

wikid guys! i think im gonna get a hockey puck! uhh where would i find one of those? so keep updating this thread we are doing an awesome job! but is there any chance that the puck would get sucked into the t/b?

aaronnn

bahaha.. damn. where's the hockey puck specialists?? i want to do this as soon as possible and i need to know what im supposed to use.. all i know is that there are those black thick disc shaped things that are maybe like 2 inches thick and 3-4 inches in diameter?? please help us with the size issue.. and if its just the standard NHL ones, we just have to go to sports authority or modells and jsut get the ones with the NHL official puck logo on it right? cause i know that on basketballs they have the NBA official size logos... that would make life easier..

dark inspire

yeah i think all the hockey puckz are regulated size, but we'll have to look into that

MikePA

Hockey pucks come only in one size.

aaronnn

NICE!! i'll be heading over to sports authority as soon as it opens!

lizard

Pucks only come in one size. I do not see how it could get sucked into the throttle body. The ouck is quite heavy with just a touch of a roughness on the edge for the clamp to be tightened down on. I still need more road testing before I remove this from my completion list.

ahahahahaha good work dj and fst!! glad people are linking it!!!

dark inspire

alright! i got my hockey puck and will be puttin' it in this afternoon, ill keep errbody updated

ou sig

did you have the duct tape over the hole originally? did you have the hum also with that?

dark inspire

i didnt have the duct tape over the hole, i duct taped the top of hte resonator and stuck it back in. i still got the hum though, maybe WOT tore part of the tape, ill tell u when i install the hockey puck!

if the whole hockey puck thing works out, i think we should dub it the "Puck Mod"

ou sig

haha sounds good, we need to figure something out soon, that hum is anoying as hell!

aaronnn

i bought a hockey puck too!!! haha
i was hella embarrased though. i went up to the guy at Sports Authority and asked him "which is the puck that people uses for pro hockey? you know.. that nhl puck. the standard round thick disc looking ones. i dont know anything about hockey, but i just need a puck, which one am i supposed to get?" then he stares at me like im retarded and hands me over the only puck that they have.. the black rubber ones that are all standardized.. if not there was the plastic orange one.. i was dumbfounded but its ok! i can do this project now! "puck mod" first thing tommarow morning

dark inspire

alright guys, the puck is in! man that thing fits so snugly! i should do the trick, i will test it on the way to class tonight. i can't wait! im stoked! hopefully this should be the end of our humming.

ou sig: yeah that hum does get annoyin after a while doesnt it? and only when u start noticing it, then u keep hearing it.

fsttyms1

what you forget about me??? i did this mod too!

dark inspire

damn kris! chill a lil :P i was jus respondin' to his post!

fsttyms1

well geesh! include me then in your statements! :P

so you try it out yet?? ya gotta let me know if i have to solve this for you guys once and for all

dark inspire

aight guys, im tryin it right now hold yup

fsttyms1

HURRY UP ALREADY :P

aaronnn

yes! hurry up sir!!! before we die of inpatience. i would love to do this once we get the heads up about it!
