Saw this on E-bay, what do you guys think about this intake?

i am gonna go with no on that one. Direct quote from their web site...
(someone needs a better translator)

"PowerChamber is an upgrade item only for NA. It is the anxious uselessness of a power down. And it can attach easily. Furthermore, PowerChamber has the effect of an upgrade of 5H.P. or more on the average. The secret of the power and a torque rise is in Chamber of worm form, and a screw type air cleaner. The internal structure is the crystal of hydrodynamics. It is filled up compressing air from an aircleaner to Chamber using air pulsation.Air with deep density is sent into Combustion Chamber like a turbo. Therefore, the upgrade which was not considered is possible until now.The functional design makes an engine room refinement more.

PowerChamber has adopted the exchange filter system which is excellent in cost performance. Maintenance is also very easy. When a filter becomes dirty, please exchange for an optional exclusive replacement filter. You then can maintain the performance of the wonder of PowerChamber."

For $4.50 less you can get the K&N delivered to your door.

Why not go for the many intakes CL members use? LMS, JoeZ, k&N etc..

 

I have the Fujita Intake and I am very happy with it, I was just curious of what you guys (who I consider experts) thought of this.

 

Yeah that kevlar chamber behind the air filter looks interesting.

 

An interesting design. The light swirling action of the air filter combined with an enlarged section that functions as a quasi-air box while reducing restriction normally found in a stock air box. However, the ends of that box shoulde be at a 45 degree angle to the rest of the pipe and not look like someone welded in a muffler. I would also add a heat shield over the top of the filter.

Another one I have seen that is quite interesting is this one, http://www.bmcairfilters.com/infoCDA.asp though I still think the ends of the box should be angled at 45 degrees to the rest of the tube.

There is another one I have seen that incorporates the air filter into that air-box like structure. I saw it in a HyperRev magazine, and when I get home I will see if I can find a link and photo for it.

 

What is a quasi-air box supposed to do? Lowering pressure to allow a higher volume of air to flow?

p.s. When searching google for quasi-air box only 3 links came up. One is from your own post. Nice air intake setup you have there. Did you end up keeping it?

I have gone through so many changes, (see page 6 of my site below), including one just this past weekend.

As far as that piece you see on that pipe, it serves partly for resonance, which can improve flow. However, in addition, it provides an area where air can gather, like an air box, but providing the least restriction possible. If you just run one long straight 3 inch diameter piping from your throttle body down to say the lower part of your vehicle, it can choke in low mph, idle situations. This is incredibly amplified at high altitude (I am at 7,000 to 8,000 feet in Mexico City) and I can tell you there is about 25% less oxygen here than at sea level.

By having this quasi-air box piece, you allow the vehicle to be able to gather up a sufficient enough amount of air so that the vehicle will not choke in low mph idle situations + in high mph situations it works to give a little extra power boost, by keeping some air in reserve, basically stored in this small expanded area.

A lot of my design for my RX are based on having an air entry or enlarged area upstream in front of the MAF, along with a bullhorn or air collection unit in the lower part of my RX300's front bumper.

This was my latest design last week (and I write more about it on my site).

Without a doubt, being at high altitude offers excellent chances to see just how far down you can bring your 1/4 mile times, with the ultimate goal of obtaining sea level times up here.

BTW, I found that other air filter I was talking to you about, but the site is mostly in Japanese, http://www.tk-tech.com/catalog11.htm

 

And then for my lower air intake, this is the latest design on the left with the old bullhorn design on the right. Basically, it uses a concept of storing air in either side (3 inches in diameter) as the vacuum created by the pistons goes to work, i.e. one side's air gets sucked up and meanwhile the other side holds enough in reserve while the other side gets replenished via ramming air front the front of the vehicle (next photo).

 

And this is what it looks like from the front.

 

For those wondering where the air filter is...there is none. I know this is a risk, but one I have been taking for more than 2 years non-stop. Reason being, MPG and power. This ain't Colorado, they have much better air and better gas. Putting a Lexus or any vehicle in this environment is like running out of oxygen on the moon and the streets are just like craters.

 

Your not kidding, lot of air box mods you did. You should keep a spreadsheet with a list of mods and track times you got with them. Nice website with lots of details. You should have an IS350. Perhaps you would be the first one to crack this engines power out of it without spending a fortune.

But it is so much bigger than the OEM ones we see on Lexus cars/suv. If bigger would be simply better don't you think it would come like that stock? Also when adding a Joe Z intake it removes one of these resonator box from the engine and so far this intake has always shown positive results on dyno.

 

WOW havent seen a MacGyver ram air in yrs, NICE

There is huge personal satisfaction when you fabricate your own mods, nothing like it.

 

When I get back to the states, I want to add an IS to my collection (no joke, always loved them). I still need to test my current modification at the track, but it is rainy season down here, so have been rained out thus far.

As far as the second paragraph, they can design air intakes that can have a larger air section and perform effectively. However, after taking another look at this, it is possible that it has an internal section in there similar to that of the Weapon-R secret intake because They make reference to a worm form and I noticed, "The internal structure is the crystal of hydrodynamics." It would be interesting to take a peek inside that structure to really know for sure. BMC air filters like I linked above does show some pictures of the internal structure and how it works so it is not necessarily a huge air box.

I have seen many pictures of the Joe-Z intake. The major thing that this piece corrects is that it eliminates the baffles/accordion like section of the OEM piece, you really want it smoothed out for less restriction. In addition, it has a mandrel bent. I take it that it has sufficient width to protect against heat, which is a major reason I like PVC if the width of the aluminium/other materials is not sufficient.

Resonators in most cases are just used to dampen noise, but in some cases they can help to prevent what I like to call a damming of air (too much air entering for the system causing a P0171 lean error/CEL). I keep one in my RX just by the trottle body (a triangular piece) just for this reason instead of removing it. Keep in mind, I haven't taken my RX down to sea level (best I have been is 5000 feet or so) in almost 2.5 years, so it will be interesting when I do get it down the mountain so to speak and run it in the 1/4 mile.

 

Thank you. It is a really joy to do.
