standard airbox modifications

[stevo_123]

hi i have been reading through the many pages about modifying my 55 reg 1.2 16v standard airbox. what i am effectively trying to achieve is an increase in sound and maintain or improve performance.i do not want to go down the open air filter route as they are bad news in my eyes.ive read that people have moved the standard airbox cold air feed from behind the headlamp into open air in the engine...i tried that today and saw no noticeable difference. i then took my airbox off and saw inside it that the filter can be replaced.

i am basically looking for some information on what to do to my airbox to increase noise and maintain power! any help will be much appreciated.

cheers S1 3VO D

catch22 situation
to get the induction noise you need an open system but by doing so would suck in more warm air.
you really need a good caf to the filter in a sortof semi open system which gives you slight gain of the caf which is lost by the semi open system but gives good noise.

 

[stevo_123]

cheers mate!by changing the filter in the standard airbox will i notice any difference in noise?

 

[W17GLE]

i changed to a pipercross panel filter and there is no change in noise. you really need a cone filter for that but then as said before it sucks in warm air.

i just did my own,

i took the original filter out, make my own template out of mesh fencing and screwed it down, i got some foam (about a inch thinck and placed that over my mesh tewmplate, put the air box back on and bam,

not noticed and down side, seems a little bit more responcive (sorry for the spelling) and after 3krpm sounds nice and deep, but nothing like a open filter,

i refuse to buy a open air filter for £80 and the original air box was made for a reason, also try making a cold air feed from the grill in your bumper, get some heat reflecting piping and run it fromthe grill to the open endo of the airbox, has worked for me, :rasp:

 

[stevo_123]

so your saying take the origninal cold air feed thingy out at the moment and replace with a longer one going from the grille into the open slot?will this add to any sort of noise?

 

[MOFO]

no but you will be getting forced induction, will give it better air flow, if you want also just cut all of the inside of your airbox out and get a panel filter, or go for the corsa way and take a drill to it and make loads of holes in the bad boy, will make it loud then but will be the ultimate chave thing to do lolo, not reccomended

 

[stevo_123]

cheers.

 

[stevo_123]

just joint a cold air feed to the standard airbox air feed and placed it at the front grille.no noticable sound or performance increase but maybe it is filtering better?!?is what i have done a good thing to do or can it damage the engine in any way?

 

[stevo_123]

anyone?

[stevo_123]

can anyone help me out here?cheers

get some mesh fencing, go to your local HKS dealer and buy a 200mm replacement airfilter and cut it to shape to make your own pannel filter.

crack the lid off the airbox (i actually mean crack it off, its bonded on!)

take an angle grinder and you will see the airbox is seperated into 2 chambers, cut all the inside out so its just 1 big chamber, glue it all back together and refit it.

take it a run and put your foot down and wait for all your mates to ask when you got your exhaust fitted lol their is a very noticeable power increase to be had doing this when a larger cold air feed is also fitted, but i had a big drop in mpg!

 

[stevo_123]

lol sounds like a bad thing to do to my new car!any other way i can do oat to improve sound?

 

[leighk18]

buy a induction kit there is many of the shelf one's you can buy if your after a big sound diffrence this probs the best way
​

 

[stevo_123]

ye the only problem with that is i will be sucking in warm air which is the complete opposite of what i am trying to achieve.

 

[stevo123]

Everything you do will be a comprimise-ie suspension = good handling/harder ride. Induction kit = more power/too noisy. Nice stereo = bettersound/more weight. Polly bushes = tighter ride/more road noise. Without exceptional design and clever implementation you just can't win. You need to think what you want from the car and go from there really. Hope this helps you decide mate

Look on ebay for a spare AirBox... That way you can fiddle with it to your hearts content and iff all goes wrong and your not happy then simply put the original one back in!

I'm doing it atm for my 182. Your not looking at much for an airbox!

Cone filters won't do a lot for a small CC car, this includes 182s.

The reason they work for the likes of Supras and Chevrolet C06 is because they need a big amount of air, and an increased amount of air will help an engine like that once tied in with other things. The increase in volume of air trumps that of the slightly increased temperature.

If you were to setup something simple like a K+N 57i (£50 induction kit) with an enclosed box, and fed a couple of cold air feeds, or just one big one) to that, you'd get the noise, with no loss in performance, but perhaps even a gain in throttle response... Not sure if you have the room in the car though..

just pull the acoustic valve out and stick an ITG panel filter in there, job done. You get a sharper throttle response and some people have said it makes a better noise too, although mine sounded the same.

Do they even do an acoustic valve in a 1.2? :rasp:

 

[stevo_123]

im an amateur i dont even know where or what the acoustic valve is.funny fooker jus coz uve got a 182!!!

 

[lewisniven]

ah, damn, forgot u had a 1.2, that might be a prob then, lol. the acoustiv valve is on the cold air feed of the 172/182 and is supposed to keep the noise down, you wont have one, sry, i shud learn to read.

 

[stevo_123]

any other opinions?will placing an itg panel filter into my air box with a cold feed going from my font lower grille be any good?

 

[JclioD]

just take the induction hose going into the airbox off........

then replace with bigger pipe, but dont attach it, just have it pointing right towards it (about an inch away) this will give you the sound and the cold air. when i find my hosting websites again il post a picture up, but my old computer died on me, so didnt allow me to keep my sites saved!!

 

[JclioD]

this is what i was trying to explain above ^^

if you move the pipe a bit further away than i have, you'l start to hear the sound more! but now i have an exhaust, i covered it up more, because it was getting all too loud

 

[stevo_123]

thanx for that mate.....also in the picture, have you attached the standard cold air feed to the bottom of the silver cold air feed and placed that down at the lower bumper?do you get a noticeable sound difference and any uincreased throttle response?many thanx for your comments

 

[stevo_123]

also will this damage the engine in any way?

 

[JclioD]

no mate, i got a piperX feed, then attached that to the grill, and i have the standard airfeed (well ive cut it to fit, its about 3inched long) so theyre both going into the silver feed as you can see, i got this feed at homebase by the way, its massive about 3inches wide, gets a lot of air in. as for throttle response, it doesnt change too much, it doesnt get worse, stays about the same....except, at night when the air is colder, makes quite a difference, and when your moving quick, so get better response when your already moving i guess 40 would be the starting speed that you'd notice it at!

depending on how you set it up there will be a big notice in sound. if you take off your original feed now, and leave nothing there (just to see what the sounds like) thats what its like. its loud. then just replace empty gap with the silver feed, and if you want more or less sound, then just move the silver feed closer or further away, trial and error thing here, its personal taste. if you leave about an inch gap, then you'l have just cold air going in (because the silver feed is wide, it covers over the area of the airbox entrance, so provides more than enough cold air which stops the hot air coming in) and you'l also have it at its loudest, if you want it quieter, then just stretch the silver feed to cover over the airbox to muffle the sound out!

no it wont damage the engine, if you get an oil based filter, that may cause issues in the engine in like 90k miles, but changing the feed has no damaging effect to the car.

i hope this makes sense, lol

let me know how it goes!

 

[stevo_123]

took the standard CAF off last night...dint really notice any noise changes that much but cud hear the air bein sucked in wen i press the accelerator...i may have a go today on puttin it to how yours is in that piccy..did u fix the silver ducting with cable tags or summit?how wud it stay still?cheers

 

[stevo_123]

just finished puttin it the same as in the pic apart from no CAF going into the silver duct hosing.havn't noticed any sort of noise change jus sounds the same to me!!!!wondering whether to convert back to standard!!!wot u all think?cheers

 

[lewba]

i got a powerteck ik for £100, its the bo**ox looks the part and sound nice and deep at 3000rpm!
dont be a pussy and get 1 lol!

 

[domjolly]

why not just buy an induction kit thats heat sheilded (there loads about!!! solves the problems of induction noicse wanted and no heat in the engine as there will be a heat shield) you could also get an induction kit with a heat sheild and a cold air flow directly into it like the pipercross Viper!!! hope that helps!! if not get an exhaust

 

[Martin_172]

ive tried loads of different inductionk its inc K&N, PiperX, universal ones etc and none sounded loud like my airbox, they gave it a slightly deeper noise which i thought was good at the time but now i cant even hear them if i try them again lol

 

[stevo_123]

martin wot modifications have you made to your airbox?i may resort to placing about 5 CAF to the gap in the airbox and hopefully this gives off a good noise!!!if this does not work the heat shield induction kit could be a solution!wot u think?

 

[stevo_123]

BUMP!

 

[stevo_123]

bump

 

[stevo_123]

JclioD just fitted it all to how your picture is....above 3000 rpm and wen i floor the gas you hear this deep sounded purr of a noise which is pleasing!!ive currently got the silver feed around 2 inches away from the gap?will increasing or decreasing this distance improve the noise??cheers for your help.thanx

 

[JclioD]

glad its working well mate! As for the noise increase, you'd have to test it, decreasing the distance will decrease the sound, thats for certain, however i dont know if from 2inches it would changed much more, give it a try, but i think that it wouldnt change much more!
