Intake Mod
Intake Mod
Before my previous thread got closed down, because of that whole thing about that thing, this is what I was gonna tell you.
I've made a cut on top right corner of my intake box, after seeing one of the guy cutting his intake box in this forum.
Mine is a bit more calculated then cutting the half of the box out. Since the ram air comes in, and the intake intake is on the bottom left side of the intake box, you need to somehow contain the ram air.
See, if you cut the intake box in half, you'll only let the ram air out of the box, and let the hot engine bay engine in.
The intake box is formed by these recessed squares that containes the air, rather than protruding squares, which helps flow the air.
So by preserving the wall of the top intake box and concentrating the air from afar from the hood air vent helps you direct the ram air into the intake intake and also at the same time helps create a funnel in which the ram air could be forced in faster.
The opening on the air box also helps bogging, which is great. The bogging is completely gone in my car as well as lower rpm shakes. I think this is due to having the opening suck in engine bay air, since you're not getting any air when you're not moving from the ram air intake.
The engine sounds mean, like it's pisssed off. The turbo spooling sounds been amplified.
Also it makes the short ram sound when the throttle is lifted.
One other thing that half cut box doesn't do well is that it could let some of the rain in the filter when it's raining a lot. By containing the opening small, you could actually have the overflowing rain water to direct downward as the box is shaped, missing the opening altogether.
In conclusion, it kicks *** and it took me 5 minutes with my dremel. It was also free.
So if you've read all this blah i've just wrote out of boredom, please go drive your EVO couple of times around the block.
Thank you.

I don't have the camera here...
I'm at work, but I'll put some up tomorrow.
I'm getting another box and putting some small breathers in on that one. 2 on each of 2 sides.
See how that works.

I think the stock intake box is designed well. The plastic they used is heat resistant rubber plastic, which I was impressed with. It resists water and actually sticks the air inside the box.
It's not like those cheap ABS plastic some other manufacturers use. It's thick too. pIctures tomorrow.

I'm definitely in for this.. I've been mucking around with my air box, and I'm curious what you mean by cutting the top right to retain forced air.
I saw the ARC induction box is just an open filter... so again, why not just take off the top part of the stock box and use the big k&n as an open filter just like the arc element?
