Question about Air intake mod

[wotugonado]

Ive wondered for a long time why the air intake on the mr2 just stops in the engine bay  s:? :? s:?   and in an effort to help with keeping cold air flowing into the turbo,
i made this



I fitted it with a 90 degree return that fits perfectly in here



and looks like this



Then bent the pipe and pinched the end to allow it to fit through here



After a quick blast it seemed to help with the air and as an added bonus made the demented squirrel noise louder  s:?: :?: s:?:  
Just want to know why this has happened   s:?: :?: s:?:   and make sure that the flow wont be anything detrimental to the engine/turbo.
If its not a problem why was it never done from the factory.

At a guess it's to avoid ingesting any water that gets splashed up in the vents when running through puddles

I did wonder about that, perhaps some mesh or something on the front ? Any ideas as to why the turbo noise is louder ?

How is mesh going to stop water being sucked in?   s:? :? s:?  

The noise seems louder because you've bought the noise close to the outside of the car.

"Mesh or something" im open to ideas.

The Hurricane intake has a small hole in the bottom of the filter enclosure for drainage. The AEM intake can be fitted with a section that prevents water ingestion.

It might seem counter productive but a small strategic drain hole could help.

Thanks, where is the best place for this do you think and what size hole are we talking about?
