hey all last night on the cruise i was speaking to peter_pan and he showed me his mcormic spice lids inplace of where the resignators where on the air intake tube. im wondering what do they do and instead of putting a plastic cap over the both of them what would happen if you made one to breathe (piece of fabric over the hole and hose clamp it down)

its a air resivoir for when you snap the throttle. if you lit it take in air from that point it wil run lean as its after the air flow meter.

no its not

its a resonator.. quiteness the intake roar down... search these forums, you'll find more info about them....

mitsu removed a couple on the ralliart from factory...

as said though if you want to remove them block the holes off do not leave them open as air entering after the MAF will cause the car to run lean as its unmetered air....

as stated, the resonators are little air storages to smooth out the inlet charge flow under rapid throttle undulation

Removing them doesnt do anything, didnt on my Rada anyways. I used my missus thyroxine med bottle lids, so tight a fit you dont need clamps but i have them there anyways.

As said, as soon as you introduce a route for air to enter the inlet without passing through the MAF you will run into troubles. DOnt do it.

sorry. thought they served two purposes. to resonate and a resovior for when you quickly snapp the throttle. my mistake.

no stress :D

cheers all i followed peter_pan and got some mcormic spices lol any1 wana buy some roast spice???:D

Bunnings sell poly pipe end caps that are a perfect fit and also you can then use sikoflex to smooth the airflow over

You will be wasting your time and money though, they do nothing when blocked, if anything fast throttle response will be down a little

removed...they enhance the look of you engine bay, unless you like the "wing from the USS enterprise" look.

i would think it would be the oppisite from my understanding (which i have no idea:D ) wouldnt the air have to travel through both resignators before entering the throttle body? so by removing the resignators and blocking then wouldnt that alow the air to directly enter the throttle body ?

Nope, the atmospheric pressure is the same throughout the air passage. Its synonymous to blowing air with your lips over and empty coke bottle to make a sound. The air is already inside the coke bottle.

one of the coolest mods to do to a magna imo.. just makes them sound so much freakin angrier :D

milk bottle caps fit perfect. do top and bottom reso's for a proper sound, some people get lazy and just do the top one

some one loves thier dictonary :D (just joking)

this angry sound you speak, does it travel right through and out the exhuast (grumpier) or a sucking noise from the engine????

just gets a bit of a growel through the intake.. even with a stock paper filter element you will hear a difference..

i've actually just turned up some little ally bungs on the lathe..

but i want to just make a nice bit of ally piping with a few barbs in it to replace the whole pipe to the MAF.. it's a little more involved than it sounds.. but not overly hard.. but i'd lave the stock air box and snorkle there with a bit of extra ducting to the front of the box..

Mitsu also remove all bar one on the Verada GTVi AWDs. I have only got the top one next to the firewall. Been thinking of removing it (waiting for the spice jar to empty).

yes these work fine, i had them on my TS when i had it. I'm yet to do it on my sports (being lazy)

don't forget to spray them black, if you won't they will stand out

Gatorade\Powerade lids fit fine.

Plus powerade have black lids so no need to paint!

Just don't use the ones with the pop-tops lol

Hahaha i thought they were blow off valves! XD

Just tapping on an oldie but inserting caps, open side up or down?

Either or. Depends on how you want it to look. Some people will say that open side down will disrupt airflow, but if they truly believe that this mod increases performance... :wtf:. This is really purely a noise mod, so it doesn't matter which way.

I think anything TJ S1 upwards only have the single resonator near the firewall.

i only removed the top one off mine as it was hitting the strutbrace when i had the ezboy pod box

my 2001 TJ1 has both top/bottom.

bottom one is a pain to get out without removing the intake arm.. managed to snake it out though :D

btw i use the caps/lids from oil containers.. thought i'd point it out since no-ones mentioned it and i'm sure you all have a lot of these lying around

S1 VRX here had all three. Had to go to the wreckers to get an intake without a resonator. But probably going to put them back later, the cannon makes enough noise as it is...

For a bit of fun take of the intake snorkel and go for a drive, between 3-4k should get a cool lil growl. Took mine off at last oil change, does nothing for the car and Im sure sucking hot air from the engine is doing nothing for my power or fuel econ but the intake sound it makes is awesome

If you are getting extra induction noise by removing resonators, then you are also getting more turbulence in the air-flow, and this can affect tuning with the Magnas Vortex MAF

You are already getting the tumble of the intake air from the shape of the manifold runners

My TJ2 came with the top resonator only, the lower position was blanked off at factory

I actually went to the wreckers and bought a lower resonator

Having this reduces some of the rough idle at around 650rpm, and is noticeable if you first improve the other causes of rough idle

I've removed some posts that were OFF TOPIC. :doubt:

They were removed from all the late model magnas to save money, not just the ralliarts :)

Yeah i still think they do more than tame intake noise, as having them on would increase the volume of the intake from entry to throttle body. when you floor it, it has more volume to use before it starts to increase volume coming into the snorkle. this is only a theory, and the efffect would only last a second, and would only have a tiny effect on throttle response for an instant i assume.

The problem with that theory is the air would have to be compressed for that to work. That is, the length of the intake has an opening at the other end, so when air is sucked in the air comes from the filter end :) of course thats self explanatory, but just pointing it out to put in perspective! The resonators have no such end, they're a closed feature, so if air is sucked from the resonator it would create a vacuum inside the resonator, which would actually reduce airflow afterwards as the resonator now is sucking air from the air inlet! The resonators are there purely to limit induction noise...

Resonators do not act as additional volumes of air on throttle openings. The resonators have an equalised pressure with the whole intake system between the air box and throttle body (since they have only one opening). They are simply there to cancel out unwanted harmonics. Their volume is dictated by the harmonic they need to cancel out at a certain rpm. The harmonic they produce is usually the same as the harmonic they need to cancel but 180 degrees out of phase (hence the cancelling effect). While their primary role is intake noise reduction, there have been some studies that have shown reducing intake turbulence using resonators has helped increase intake velocities through the intake tract via smoother air flow.

cool!! didnt think about the resonater having no opening. i do wonder if they have an effect on the intake velocity like you say. if the intake runner lenth is tuned to the engine, i wonder if the resonaters have any effect on this. i doubt it just brainstorming!
