Greetings All.

Do the intake resinators make a BIG difference in inducion note...

At the moment i have the snorkel removed and the top resinator...but there still is a fairly largish on near the TB...

Will it sound even meaner once i remove that one as well...?

Cheers,

I noticed a difference in intake noise as well as exhaust. Sounds much better.

on my 2nd gen they made a huge difference, then i took of the piping from the Airbox to behind the headlight and it was an even bigger difference. When its under load at like 3000rpm it sounds tuff as.

So on a 6g72, If I remove the Resonators , Does the Exhaust Change Note aswell, If so can some one describe it to me????

For the moment I am keeping the Factory air filter, am I better to leave the Resonators on ???? and just plug it up with a Millk bottle lid???


I was thinking of sticking one of those Party Siren Whistles ( the Round ones) to give mine that Super charger sound once I have removed the top Intake resonator, do think it is a Bad idea ???

its a mod thats not goin to cost u nething at all,
so i rekon just go out and do it and see yur results, if u like it or not,
as for the whistle i wouldnt because its after yur filter and could let anything into yur engine

yeh, super glue it to the snorkel or something lol

i took mine out...makes a fair bit difference, but i can't really hear it anyway coz the stereo is too loud :badgrin:

but yeh, makes intake sound a lot beefier

:stoopid:

I have taken mine off about 3 months ago. The induction noise nice but I was worned by my service centre It is not a good thing to do because, It suffercates the engine, from backup air that is stored in the resinator's. Is this true I have had no problem's till know :D

well, i have no idea why you took the snorkel off, unless you want to lose 3-4 kw? why would you want your engine receiving less cold air ?

but yeah, when you plug the resonators up it will sounds beefier, it probably takes 1 minute to do , and test.



have fun

mate, ya replace the snorkel wif a cold air induction pipe and run it down to the front bar some where...usually in the fog light spot

NO! Air will bypass your Air Flow Sensor and the incorrect fuel amount will be added. You will ping and stutter.

Thatnks for the Technical Diagnosis before I made a Big boo boo.
I may try and place it in the Snorkel area or not bother

it makes a fatter sucking sound, but this sound dies down eventually.

Intake resonators don't store air - myth. Plenum does work a bit like a reservoir, tho.
Removing snorkel is a good idea - provided u replace it with CAI (plenty of posts here for that). I'd do it from PVC pipe not crinkly flexi pipes, cos air tends to travel along the inner surface of such pipe and if it's not smooth - well, u can guess how bumby the ride for the air would be. :cool:

u r a genius, i loaded my pod with flexi pipe rigid style walls and i can notice the car stuttering a bit like its getting bumpy air in it. i mite have to change the pipin i use then.

Thats what theory would say, but the dyno says it doesnt matter :) the simple fact is the standard snorkel hurts your airflow and a big f/off pipe sorts that fault out, your tb is less than 65 mm, so a crinkly 90mm pipe is never going to hurt it, a smooth 90mm pipe is just a little bit more overkill.

Matthius

Genius? Not taking credit for this matter but thanks anyway.
Stuttering? Would not be cos of the ribbled inner surface, I'm quite sure. Such surface would only result in to less-good airflow in general, not that extremely bad flow. But change it to PVC anyway. Perhaps u have faults elsewhere?

i made the mod.. trailed it for a week. Made absolutely no difference. I think its a case of if you want to hear a difference and genuinely think it will make a difference, then you will probably hear one, but in reality, it makes no difference imo

U'd need to ask Slayer how much diff it made when he changed from crinkly crap (rhimes nicely!) to 90 mm PVC in his 3.5. (15.4 sec in 1/4 last week)
It's not that much of the size in the pipe which is relevant, as long as it's above some 75 mm, but cos the air travels bad on un-even surface.
In a 3.0 L donk, like mine, it makes more diff, cos it revs higher and power drop isn't that steep.
Dyno? What I know, there has been some 4-6 kW improvements from snorkel to smooth CAI in 3.5 donks. Their max power is at 5000 and drops quite steeply after that, unlike the 3.0.
In other words, even from worst to best, the diff isn't huge. But still very cheap kWs!
And obviously, the more one has breathing mods, the more the CAI becomes relevant.

Also, as a rule of thumb: a 1 meter long 100 mm pipe with 360 loop has same flow properties as straight 80 mm pipe. In other words, few ~90 deg bends in a CAI pipe reduces flow by 20%. Hence better to start with larger pipe and it then narrows down to the size of TB - which would need to be smaller anyway to produce some air speed there - but that's another thing all together. :)

Perhaps u have faults elsewhere?

its a TR. faults are everywhere. my roofs caving in, wheels are bent, zorst scrapes on da ground, trannie goes clunk.

Hah, yee. Some AMC guy did a dyno on these resonators. Experienced a 0.5 kW diff. I reckon there must have been a change in the surrounding airpressure to "gain" that much power. Yep, totally unworthy job if you're after power gains. They're only for noise suppression.

haha the exhaust scrapes on the ground cos you put a massive cannon on it that sits about 3cm's off the ground :P

and i covered the gaps in it with alumimum which is buring and it smells like rotton eggs. dont drive behind me to close.

Nopes I don't, I work with a dyno, have access to it and tried, 0 difference in an otherwise standard 3.0, maybe in a modified 3.5 it might start to make a differance, but then again, the 65mm throttle butterfly would most likely hurt you first. The reason the CAI mod yields good results is it rectifies a factory oversight, not because the engine needs 90mm of intake piping.

Matthius

P.S - with my current setup of crinkly 90mm I gained 6kw, I have a thread around somewhere with the dyno sheets on it.

Better fuel economy at least.

U lost me there - 0 difference and then 6 kW gain. Could u specify the 0 diff case?
65 mm TB yep, and then perhaps some less than 30 mm dia intake runners and very narrow valve opening.... your point was?

He's talking about the resinators, he found 0 gains when removing them, and putting in a CAI he gained 6kw :).

Ah, makes sense then.
I'd like to see comparison with really crappy CAI tube vs PVC on a dyno.....

The 0 difference was between the crappy intake pipe(flexi pipe) and pvc running with an open bonnet straight out from the airbox(ie: not from under the bumper but over the radiator support with the dyno fan blowing down it) the 6 kilowatts was what both of them achieved over the standard intake snorkel.
My point being it doesnt really matter how smooth the pipe is as your rectifying a factory fault, not making a enth enth performance modification, on a standard engine it makes SFA difference wheather it's polished and smooth or rough as guts, it's just the change of air pickup points thats makes the difference.

The intake runner and valve diameter is another ball game as only one cylinder breathes through them meaning they do 1/6th the work of the TB, whereas the 65mm TB has all 6 trying to gather air from it, say the engine flows 300cfm of air at a peak, each runner would only see 50cfm, hence smaller size.

Matthius

It wasn't really a question.... :)
At 5500 RPM a 3.5 L donk gushes some 160 liters of air per second. So, each intake/cyl would get ~27 L/s (1604 L/min). Dunno how many cfm's that would be. But it's plenty anyway. Hence minor details at valve seats, runners etc are relevant.

Hmmm.... :doubt:
Ok then....
I think I leave this now.

where is the other one you guys are talking bout?

i took the big one off (kinda shaped like a slice of pizza...lol) but where is the other ones...

i havnt reeeally looked, only took the big one off because my strut brace that i put on last night was hitting it, and i didnt want to damage anything, so i just took it off...

(please flame if this is a stupid question...lol)

its just under neath chris
i'll post a pic

http://i2.photobucket.com/albums/y5/mehhh/Picture048.jpg

aight... i cant get my head under there atm.. ill have a look once i get home...

is there only a noise difference, or is there like a .02kW increase lol

cheers meh, ill look when i gets home :D

no worries
its just under the bend at the back
easy to find

yep, i can feel it... it feels like a milk cap already lol...

whats actually there?

i did the same but yeah it feels like a flat one alredi, but iknow 2nd gen has two side by side

ah right.. so no point on ours darky? only the big '' un up the top?

yeah i think so coz they hav no clamp either

yeah i think so coz they hav no clamp either
sweet as then man, thanks for that...

i didnt notice a noise when i did the top one, was more out of necessity though for the brace :D

so the ralliarts dont have a bottom one
hmmm there goes some ones theory about havin more air to suck in

so the ralliarts dont have a bottom one
hmmm there goes some ones theory about havin more air to suck in
maybe they have a bigger intake overall?

dunno.... wasnt my theory at any rate... SORRY TO WHOEVER ME & DARKY DISPROVED lol

well, i have no idea why you took the snorkel off, unless you want to lose 3-4 kw? why would you want your engine receiving less cold air ?


have fun
i doubt there would be a difference,
maybe its one of their things to add that bit of extra power that the other magnas dont have

i dont know how it would work so i cant comment im afraid meh..
