beautiful intake!

I don't think so. That carbon fiber piece looks like an asthetic piece. Has nothing to do with the intake. If it does, then it would do a really pathetic job. I too saw the picture in the diagram, but how would any air reach that side duct as there is no position in the front of the car to facillitate that.

I am talking about the side of the airbox facing the battery. I am assuming it is for connecting the factory cold air intake tube, but I may be completely wrong. Having a gaping hole that big would somewhat limit the ram air effect as a vacuum would create suction and would be needed until under speed, when the ram effect would take over.

this is from their site.


and that plate that goes over the battery helps direct, and isnt just for looks. although it sho is pertty.

No, I saw it and noted in the post above you. I can't possibly see how in God's green earth that will provide any air to the side of the airbox. The drawing shows little blue streaks going to it. What air is entering the car that could curve itself around and go into that hole?

Here is the illustration:



What is goofy is the air going in the grille area, curving to the right, then making a curve to the left to enter that hole. Maybe they did an aerodynamic study, but I have never seen air make multiple curves on its own without some kind of tubing or ducting.

ahh now i see where you edited your previous post. i assume the cf plate the bolts over the battery routes air that comes in from the grill area to that hole.
i don't know i am just guessing. it must work and for $1200 it better lol

What you previous said is probably correct as the diagram does show air entering the grille and going into the hole. The other blue stream shows the air going over the hood and into the ram air tube which makes sense.

To me, the cf flat piece on the battery just seemed like a dress up item, some added bling. I learn something new everyday I guess.

That would be sick if some body made something like this for a turbo application, or would that be bad? Seems like it gets some nice cool air and its made from cf not aluminum so heat is less...

Me personally, I would want the shortest intake before the turbo inlet due to the throttle response being better with the short ones. It's gonna get heated up by the turbo anyways and then cooled down by the intercooler. The intercooler is the key in that equation. It needs to be the right size so that there's not a big psi drop and still cools down efficiently. It all would depend on the boost pressure that you would plan on going with.

I think that vent on the side is for the air to pass through when the throttle plates close at high speeds. That way the high pressure air can pass through without pushing on the throttle plate or push the intake hose off when high pressure air just slams into it. The air has to have somewhere to go. No? Also When the air is blasting in there and the plate closes it will jusy over flow back out through where it came. With that vent it constantly has fresh air blowing past the filter. This way the car will always have crisp throttle response.

don't we all?

i dont think their diagram is saying air from the middle of the grille will flow OVER to the right side and into the intake. i think its merely just to show that airflow coming in from that side (which im sure there is!) will make its way to the hole.

I also think that the plate that goes over the battery and covers everything is to maybe HELP incoming air...less obstructions(or placed for air to be trapped) for the air flow. that way there is less turbulence and a more direct/smooth flow to that area!

Also note that ECU cover can play a role in guiding airflow right into the intake hole.

looks pretty cool

[1cleanfg2]

Baller intake !!

[Terma]

Are the gains even worth 1200?

[trickyazn]

^.. no lol still looks cool nonetheless.

going on with what you were sayin soxfan, but adding in some more fun and a lot of imagination, if what your saying is true... what if you could somehow incorporate a hinged flap/door or a modded "blow-off" valve to that large opening so its got higher pressure when its accelerating to suck in the air from the scoop and then when you let off the throttle the "blow-off" door/valve will open juss like a turbo, hahaha... ya, it probably defeats the purpose of that battery cover cf piece and i know there probably isnt that much pressure to open and close something like that, but hey, it could be cool, hahaha

Actually, the plate has nothing to do with the rammed air that comes from the cowl area. I have never seen a ram air system using cowl induction with a gaping hole in the side. Doesn't make sense. It detracts from the vacuum and the ram effect. It must have some purpose, but I just don't know. I personally believe it is there to be connected to the factory cold air intake tube, but I may be way off. Soxfan143 suggests it may have something to do with the throttle plate, which might be a possiblity. This really has me confused.

i think we are looking waaay too far into this intake. LOL

you could EMAIL the company if its bothering you that much. the company is VERY well known, and a lot of R&D goes into their products as they are DEF vehicle specific.

WORD!!! So sweet!!!!!!!!!!!!!!!!

Um, first of all, I started a thread that has over 38 pages in it. People are taking this seriously. This is cold, hard science that cowl induction provides the best place for ram air.

Secondly the company is Japanese, so they may or may not respond accordingly. The hole is obviously engineered into the airbox, but for what reason, I am not sure. I was kind of hoping the OP could help us out.
