I've been had! My Fujita is actually Pieco****a

Sky Hi · 08-13-2007, 10:30 PM

I hate to admit it, but I am convinced that my Fujita CAI is a nice looking power reducing farce! I really wanted to believe otherwise, but with all the discussion about CAI's and air temperature I had to investigate things further.

I have always had very good luck on other applications using low restriction intake systems and K&N air filters. When I bought the Sky, I wanted to clean up the looks of the engine compartment, add some performance and gain a little intake sound too. The Kappasphere Fujita CAI looked great. They advertised Dyno charts showing a reasonable performance increase. This appeared to be a great product from a reputable company... I took the bait.

I removed the CAI and compared it to the original air box and intake system. I was very dissapointed with my findings and frankly am P O 'ed with what I have found. At first glance it looks like Fujita did a nice job of increasing the diameter of the intake tube, and necked it down for the MAF sensor to carefully match the original diameter, so the sensor would read correctly. They then increased diameter to a performance style air cleaner. Another thread indicated this was not the case and unfortunately they are correct!

This is what I found:
The throttle body is 65MM. The Fujita begins at 65MM, expands to 73mm necks back down to 65MM where the MAF sensor mounts, the expands back to 73 to the filter. The filter is in a similar location as the orginal intake, however it is not shrouded from the engine compartment and will draw warmer air than stock. ( how much warmer is debated in other threads).

The stock system begins at approximately 70MM and expands a little after that (coudn't measure inside). There is a large volume chamber that feeds into the side of the tube through a 55MM hole. The tube continues to the airbox. The MAF is located in the inlet of the airbox where the diameter is 70MM (vs. Fujita @ 65MM). The airbox contains a large flat filter. The inlet to the airbox is an oblong hole with an area that is a about the same as a 70MM round hole. There are 4 tuned chambers on the intake horn that appear to be for silencing purposes only. The intake air is drawn in directly behind the fake grille and is shrouded from the engine bay heat.

The stock system is larger than the Throttle body everywhere. The Fujita is the same diameter as the Throttle body where the MAF sensor is located. The sensor is rather large and restricts air flow. The diameter needs to be larger than the throttle body to flow the same air. The Fujita design is restricting air flow! Worse than that, because the diameter is different, the sensor will not read correctly, causing the computer to think it is flowing more air than it is, and injecting more fuel accordingly. This mismatch in diameters is a major engineering blunder in my opinion.

I then compared air filter elements. The Fujita is a conical competiton style filter. I measured the actual area of the filter material. It has 38 pleats x .7 in / pleat x 4.75 in length. This is approximately 126 square inches of filter material. The stock flat paper filter has 37 pleats x 2 in/ pleat x 8.2 in length. This is approximately 607 sq in of filter material. THE STOCK FILTER HAS ALMOST 5 TIMES MORE AREA.

In conclusion:
1. Fujita CAI has a more restrictive tube that is restricted smaller than the throttle body when the MAF sensor is installed.
2. Fujita has a much smaller filter that likely flows less than the stock paper filter.
3. Fujita has less volume, and will act more restrictive than stock.
4. Fujita draws warmer temperature intake air.
5. Fujita is improperly designed to use the MAF sensor without recalibration.
6. Fujita has a nice shiny appearance and makes more noise.

I have reinstalled my stock system. Performance measured by the Butt dyno is as good and probably better. I am opening up the intake side of the airbox to be a little more free flowing and have ordered a K&N replacement filter to be sure it flows more than the CAI. I am undecided as to force air into the airbox, I will take some temperature measurements and decide (Probably won't).

It is thoroughly disgusting to me that a company would market this product without doing some basic engineering homework. I feel robbed.

Interesting stuff. Makes me wonder though. While I'd expect the ECU can usually compensate, at extremes will the impact on MAF readings potentially cause problems. Guess I'm thinking about wideband input at wot...

My system eventually compensated for the more restrictive CAI system and different feedback it was receiving from the sensor. I don't know how long it took to recalibrate itself. I know it takes a while just switching gas octane from regular to premium. I ran the Fujita for over a year. My mileage was good.
Perhaps the Fujita dyno sheet reflected an actual HP increase because of richening the mixture initially before the system compensated for it. There is a big difference in flow at the same velocity (which is what the sensor reads) when diameters change from 70 to 65.
I share your concern about how much can it recalibrate itself, especially at WOT.
One thing is apparent, adding a larger throttle body would be a big waste of money when combined with an intake that is more restrictive than the stock throttle body!

Are you willing to sell your CAI and if so how much?

shabby · 08-13-2007, 11:53 PM

So fujita screwed up the 2.4L intake too? Whodathunkit, look what they did to the gxp/redline intake. I posted my findings on the solstice forum.

Sky Hi 4. Fujita draws warmer temperature intake air.

Based on underhood temperature measurements I have taken, the air temps in the stock intake area and the CAI intake area are the same.

Ag94Whoop · 08-14-2007, 04:45 PM

only once you are moving....

so the question is, do you like more "get up" from stop than you currently have?
If so, induction filters are NOT the choice.....if you want mid range power gains once moving they are a great choice

JRinKY · 08-14-2007, 06:26 PM

Ag94Whoop : only once you are moving....

CAI and stock intake temps are essentially the same as each other whether moving or stationary. Both are higher than ambient when stationary, but are essentially at ambient for anything above 30 MPH of road speed.

I don't drag race, so I tend to think of performance in terms of having the car in motion.

Regarding the different tube diameters measured for the Fujita and the stock intakes: Unless you have a flow bench and can test them, you really do not know which flows more air. Intuitive thinking will very often get you into trouble when looking at fluid dynamics, especially with the pulsed flow that we see in engine induction and exhaust systems.

Ag94Whoop · 08-14-2007, 06:44 PM

the stock air box works well when given a fresh air source

I have let several people with CAIs drive my car and all say it has a lot more jump from standing still and feels about the same when moving

1/2 price of new and I'll ship it.
It still looks new.
If someone on the forum doesn't want it I'll list it on EBAY.

I've noticed it doesn't have the power accelerating after a long stop as after it has cooled down from moving. It makes sense. Maybe I will go to a forced air design...

The GMPP intake is a good choice also. On our test car, although peak hp was lower than stock, you gain a good amount of useable power in the midrange.

Let me assure you that more then just some basic engineering homework has been done. This product was dyno tested (hence the numbers) and then some. I'd like to touch on a few topics you brought up to clairify things.

First, you mention the lack of a heat shroud. I am curious how heat is going to travel forward from the engine bay to the filter when the air flow is going the opposite direction. This filter sits in front of the radiator not on the side of the engine.

Also in regards to the diameter at the MAF, this topic has come up before. In fact another company, who's name I will left unsaid, tried a larger tube with a larger MAF section and ended up having to sell "adapters" (which were nothing more then inserts to neck it down the the size we use in the first place) in order to get the car to run properly. Just remember, it's not always the size of the boat that matters...

This intake was tested over and over again on a dyno to get the system we now sell. If there was any doubt in our mind that this product was a rip off to our customers, we would not be selling it. End of story. You can believe what you would like, but we stand behind the products we develope and sell which is why we have the loyal customer base we have for both this car make as well as the Lotus.

Do some searches on the forum and you will see all sorts of conversations on this topic. I have yet to see an argument that undoubtably prooves the Fujita intake to be a gimick.

Brian

Dear Members,

I wanted to take a moment to give you a little background of Fujita Air. We have all been in the industry for many years now. I personally was the VP of Racing Sports Akimoto and a founder and still owner of Injen Technology. I resigned from Injen and helped start Fujita Air in mid 2005. We have an in-house Dyno Jet 248C, also used by NASCAR. This is a well respected machine. Most of us at Fujita did come from Injen, Skunk 2, DC Sports, and several other companies in the industry. We are carried at Pro-Motion Distributing, Kappasphere, Saturn Motorsports, Arrow Speed Warehouse, Performance Tuning Inc., Nopi, Honda, Mitsubishi, Toyota Dealerships throughout the US and several other well known names in the industry. We are a SEMA member. We were chosen by Toyota USA to build their Yaris and recently chosen by Scion to build a SEMA 08 xB. We work with Greddy, Tein, Volk Racing, Hitachi, NOS, and Sony on all projects. We are serious about this business and stand behind our products. We are always striving to better ourselves and most importantly, offer great customer service. We are not perfect but I can assure you, we are improving everyday.
In regards to testing, we conduct many tests. We try different diameters, different size filters, we swage the pipes, flair the pipes, etc. We maintain factory air fuel ratios in regards to factory mass air flow sensors. We have countless configurations at our disposal, allowing us to offer the public a proven hp performance product. There is no reason to try to cut a corner, offering a smaller diameter. Why is your pipe for the Sky/Solstice not bigger? How can somebody with a ruler scientifically conduct hp tests? How can the visual eye be the reason somebody says a product does not work? We can't do that. We can't eye-ball something and say "Here you go." This is why we invested in Dyno Jet. This is why we invest in tooling, aluminum, filter testing, etc. It makes no sense for us to offer something that does not work when we have the tools to build something that we can back up. Our pipe was configured with our filter. We are not here to rebuild the tube with the same filter surface area as stock. That is not what we do. We use the data from all of the different prototypes we make and then mass produce the one that worked the best.
The members on this forum are smart, it is obvious. Don't let somebody change your mind based on theory and not on the facts such as dyno test results, air fuel ratios, etc. I see this all of the time. I especially see people that have strong opinions and they don't either a) have the part b)own the car c)have not done any tests.
Thank you for your time and support. Feel free to contact me through info@f5air.com.
Please note, I am not on this site daily so email me please, don't PM. Thank you, Ryan

cerberus · 08-15-2007, 06:35 PM

Please show us some INDEPENDENT dyno tests that resulted in an increase in HP. I haven't found any. If your product is good, they should be available.

F5airRyan · 08-15-2007, 08:20 PM

So if a company does not have any independent tests than there is no proof the product works? Our product is no good based on "You can't find any independent tests?" Hmmm?? We invested in a dyno so that we can prototype in-house and be able to make modifications on the spot. Most manufactures in this business that make performance products display their numbers using their equipment.
It would not help any manufacture to give bogus numbers because the customer can always get a dyno at a testing facility.
We have many systems that have been tested by customers for different vehicles and with some great feedback. All we can do is provide true data to current and potential customers. Each person can make a decision from there.

SpecRaceM5 · 08-15-2007, 08:24 PM

If you want independent numbers then feel free to have your car dyno'd. The numbers we provided from Fujita were using our car when the product was first developed. We are not here to lie and post false numbers. We are here because we are enthusiasts. Those are the actual numbers taken with the intake on our car. No tricks. Look at the other products you have from us. We have not released anything we wouldn't put on our own cars. Neil and myself were physically present when the intake was developed at Fujita. We have proved to be nothing but honest in the past with all of our customers and products. We have provided dyno numbers for the products. I can have 100 more dynos ran on the intake and this topic will still come up. That's just life I guess. I have given you responses on both your theory issue and flow theory. The dyno numbers and air fuel numbers are hard evidence that the diameter pipe

Most manufactures in this business that make performance products display their numbers using their equipment. It would not help any manufacture to give bogus numbers because the customer can always get a dyno at a testing facility. We have many systems that have been tested by customers for different vehicles and with some great feedback. All we can do is provide true data to current and potential customers. Each person can make a decision from there.
