Actually, if it works I'll buy Code 3's intake. But it seems cheap to duplicate and temporarily test it out. I wouldnt trust my own DIY in the long run.

Basically the panel at the end of the intake, near the firewall, is removed and replaced with a filter. The rest of the intake stays stock.

What material could I use to efficiently filter air if I were to try and duplicate this?

 

Any Engineers in Fluid Dynamics on this side or anyone have a buddy who is?

I'm a little skeptickal on this one. The code 3 filter shows improvements on the dyno where it can draw air around the firewall, but... At driving speeds wouldn't that actually be a place to loose intake air? What ever intake one is using the air moves up towards the throttle body and then before it gets there - instead of being restricted (factory y) there is now a hole there


Bernoulli's principle, physical principle formulated by Daniel Bernoulli that states that as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. The phenomenon described by Bernoulli's principle has many practical applications; it is employed in the carburetor and the atomizer, in which air is the moving fluid, and in the aspirator, in which water is the moving fluid. In the first two devices air moving through a tube passes through a constriction, which causes an increase in speed and a corresponding reduction in pressure. As a result, liquid is forced up into the air stream (through a narrow tube that leads from the body of the liquid to the constriction) by the greater atmospheric pressure on the surface of the liquid. In the aspirator air is drawn into a stream of water as the water flows through a constriction. Bernoulli's principle can be explained in terms of the law of conservation of energy (see conservation laws, in physics). As a fluid moves from a wider pipe into a narrower pipe or a constriction, a corresponding volume must move a greater distance forward in the narrower pipe and thus have a greater speed. At the same time, the work done by corresponding volumes in the wider and narrower pipes will be expressed by the product of the pressure and the volume. Since the speed is greater in the narrower pipe, the kinetic energy of that volume is greater. Then, by the law of conservation of energy, this increase in kinetic energy must be balanced by a decrease in the pressure-volume product, or, since the volumes are equal, by a decrease in pressure.


...in other words - instead of drawing air in from near the firwall it might be ecscaping out.

 

Wow, thats technical stuff haha. I always figured supercharged cars sucked in air much faster than N/A, so things like what you're mentioning wouldn't matter as much as it would on an N/A.

But I do get what you're saying.... Hopefully more left-handed people chime in.
