CUSTOM INTAKE DONE AWESOME RESULTS W/ BLITZ HKS APEXi TRUST READ NOW WHY ITS BETTER!!
Wicked, isn't it funny that people call this a "ghetto mod", when in fact, you could claim it is 100% american built and ask for additional $$ based on this fact, in fact, I find that things you do to your car on your own (typically) you take more time and care to make it even better than a pre-bought piece.
btw, I was at autozone getting some brake pads for my wifes car and I head over to the ghetto section, and guess what they have??? AN adapter very similar looking to the one you make, but it is made out of "composite" (in other words "Plastic"
). I rushed home and it fits my K&N perfectly.
Now I just have to find the time to install it and figure out a good way to make a heat shield (if you have any ideas let me know, I and thinking about cutting up a bucket and painting it?? any other ideas??)

a VELOCITY stack uses the venturi effect. how?
well first you have to understand what venturi is. venturi is when fluid speed increases when the fluid is forced through a narrow or restricted area.
simple diagram.
[A]>=<[B]
if you have the volume of A to goto B. so if gas A, say like normal air, it has to speed up through a narrow passage, so that the same amount of air that went in, comes out at box . sorta like conservation of energy.
well your MAF is a 3" diameter hole.
you have a 9" diameter pop charger filter. how do you get air from a 9inch wide filter into a 3inch hole? simple a velocity stack maf adapter.
its smooth gradual shape allows the airflow around the top edge of the toroid accelerate toward the center. (Toroid/torus, its like the shape of a donut) place a marble on the outter edge of an upsidedown bowl, and see the marble accelerate. same idea.
air will speed through the MAF at a higher rate than if you just have a simple filter at the end of it.
so if you do your dyno test again, with NO filter, and slap on just the velocity stack, you should get some good numbers since its sucking air from everywhere.

OR B: Forced induction. Why don't you do the test so you can see that the whole velocity stack is somewhat tricky... I will keep saying this and AIR FILTER is just TO FILTER AIR, nothing more nothing less... Finding the less restrictive air filter isn't always the best... AS YOU CAN SEE FROM THE RESULTS, the CHINA filter made more power because it filters less and MORE AIR!!!! is getting inside. Plain and simple.

LOL, I agree with you. Actually this is funny. China tubing, MEXICAN inventor, AMERICAN WELDING IT, GOING ON A JAPANESE CAR... Yeah... GHETTO!!! LOL
But yeah, I do take more extra care and precautions and anyone doing anything custom normally does the extra steps to make that final touch, actually my friend who helped me welding it is now going to make his own. HE has an AEM intake and is going to make a 1 piece design. You know that plastic stock piece, well he is making that too all one piece! Creative, maybe.. UNIQUE yes! Good luck with your intake, E-mail me if you have any questions or give me a call i'll give you my cell phone.
GOOD LUCK!

Nice job...
This is good advice but for some, time = money (but that varies for each individual).
For me, spending over 2-3 hours on driving around, measuring, and fabricating this would run (in time spent) way over the $120 it costs to buy the JWT that includes the filter, cnc precision cut velocity stack adapter, mount, and heat shield.
But sounds like you had a great time putting it together... it's time well spent when it's a hobby. Again, well done on your intake/exhaust mods.

any plans for production wicked4u2c...? since i am the reason for your mad creation i should be privy to a small percentage of your profits
Installed, Actually was very very easy when I got the adaptor.
car sounds same at idle, at WOT sounds totally different, a lot deeper, meaner sound. My car use to have a lot higher pitch sound at WOT (and the raspiness at 2-3k rpm, from the test pipes) now it sounds totally different.
Is that what what the JWT and what wickeds sounds like>????

I already did the same thing and used a plastic heat shield I bought at autozone. I also got negativity when I first posted beacuse you were only saving xxx amount of dollars. I did it not only to save money but I enjoyed doing it knowing that i ACTUALLY DID IT MYSELF.

Just a question regarding the Venturi effect.
How exactly does a "velocity stack" improve flow? All it does is increase the speed of the air, but it will actually reduce the mass flow through the intake. Look at it this way - if you have a restriction (venturi) in your intake, we all know that the air will speed up. However, in order for the air to be accellerated, their needs to be some force acting on it. This force is the pressure difference between the one end of the restriction and the other. Now, the only way to create a pressure differential is to build up air on the upstream side of the intake. This means that in a N/A application, where engine vacuum is the only means of creating pressure, you are simply not allowing the engine to get as much air as it otherwise could. To me, this sounds like a bad thing.
I have not had significant experience with the design of venturis on car intakes, but from a fluid dynamics perspective, I don't yet understand how they would help. The only area I can see them helping is in the actual intake runners to each cylinder, where the air velocity can be used to help improve the flow into the cylinder. However, having a restriction right after the air filter doesn't seem like it would help.
Anyone have scientific reasons why these things are useful and how they work?
Thanks,
D'oh!

I am thinking of making one similar to this. Here is a link to how the guy made one for his BMW.

I am in the process of building an intake but frankly did not consider the different densities or mesh sizes of air filters. Something I am doing a little different is coating the tube (MAF) and heat sheld with a liquid ceramic coating. I have done alot of testing and the ceramic coating will decrease the tube at any temperature, and incresing the cooling effect of the metal over 50% once it exceeds 200 degrees. I don't understand why intake manufacturers have'nt taken advantageof this process. Also, I am using a used stainless steel 2-qt open container from a restaurant supply company as my heat sheild. If this works I will build a 2nd and have it ceramic power coated.

COMEON man! This is not a 70's DATSUN. I think your ceramic coating is a good idea, but a Restaurant supply container?
