Involuntarily volunteered experiment

sorry to dig this old topic,dun wanna opened a new topic.

u know sometimes there is a box or a hollow compartment inside air intake box.
i read in a renault forum that the box is to produce air swirl.is it true?

anyway,on the surbo or whatever air swirl thing,
i exp very minor change.engine is a bit more responsive at certain rpm only.
thats it.no powet gain,no fc improved.

Well.. if you somehow manage to swirl the air after the air filter..think about the 'butterfly' at the throttle body.

It would greatly disrupt the so called swirled air.

The best thing to do is try to make your air intake cold by using heat shield and draw air from outside the engine bay.

Actually I don't know or understand that box too. VR and Hyundai also have it. Just attached with a small hole in between. What to swirl as it is before the air filter, and I have more swirls from my VR turbine....hhahhaha

I have seen the box on my blm,waja,even on my wife viva.
the wira,kenari does not have it.

could it be that its creating suction force.sort of like a super light pressure like having a turbine?

Where is yours placed? If before air filter it cannot help in anything as far as I know.....

all are before the filter...
will try and serch whats the purpose.
cant sleep well not knowing the reason it was design

found it.
its called a resonator box.somehow air did flow in reverse and the small bix will allow the reversing air in the intake to occupy the box.
this will allow air flowing into the engine encounter less resistance.
this small box actually helps increases power by allowing better air intake flow.
it also helps reduces engine sound to comply to some regulations.

removing the box will probably produces stronger intake sound but at the expense of restrictive intake flow.

I was gonna reply about the resonator box but it seems you found the info yourself.

And surbo is a restriction, it won't improve anything. It choked my car the last time I tried it and the powerloss was very obvious. It's kinda like you drinking from a straw. Jam a barley inside the straw and using the same amount of suction you'll notice less drink getting into your mouth. Same concept. Why anyone would want to add a restriction to their intake is beyond me.

Thanks brother, but still cannot see the use as it is located outside of air filter, especially on the VR. If you say air flow then anywhere in the flow after air filter I can understand...
Need to be more technical already.....

I read back on your post and saw your picture. First thing came in mind why you block the air flow......hhahhahhahaha
