I wouldn't know where to find the pic, but someone had drilled a hole down toward the brake duct, but didn't interrupt the flow to the brake. They put their intake right next to it, where there was still high air flow.

now... where its coming from stock... in the center... there has to be a reason why they made it draw from there is there any reason that people know of?

I am thinking it draws air from the area before the radiator, where the coolant resevior resides. I never understood that about car manufactures, they always seem to stuff the air intake inlet ind the weirdest of places, they must know something they ain't telling us.

Thanks Lee that was the image I was refering to. Although I wish they had a profile of a TII for comparison

the more I look at that, the more confused I get.



so, if they arrows pointing away from the car are lower pressure, then how can that be with air ramming right into the front bumper (@ FTP light area)?



if the arrows pointing away from the car are greater pressure, then how can air be exerting pressure on the rear bumper?

you'd think thatd be smooth and round like the car's own shape but that is just confusing and how would that differ if i was to put a universal wing on it

Air flows off the body in the direction the arrows point is what i think it is.

yes someone please learn me on this

its just a their to examplify pressure, the farther away the centerline (the line that the arrows point to) the lower the pressure zone is on the surface of the car. It had me confuse too, but it doesn't mean the air follows the line, it simply shows measure of pressure. Any of the arrows that are that are pointing away from the surface mean their is negative pressure, the longer the arrow the lower the pressure is compared to atmospheric pressure. When you have arrows pointing towards the surface of the car that is where pressure is higher than atmospheric pressure.

The low pressure zone in the front of the car by the grill is called the stagnation point air particles are being forced to slow down and particle counts get packed like a britney spears concert, with no option to go forward air partcles turn away from the car and start accelerating up and over the the hood of car, because when air travels faster the particles spread out more, lowering the pressure. So that crazy mound of low pressure you see at the front of the hood is caused by air beind deflected off the grill and zipping over the hood. I am looking at airfoil pressure diagrams and they do very much the same thing. The leading edge has a massive mound of low pressure on it. cause that is where air is accelerating and moving faster.



So think of it this way, if your still confused a bit, at any poin on the surface of the car, where the arrow is pointing away the farthest is where the air is travelling the fastest, meaning less pressure. Where the air is pointing in the car is just the opposite.
