Akuma Motorports 370z Intake

AkumaMS · 07-15-2012, 10:33 AM

Thanks for the interest guys. Let me clarify a few things. The group buy will be up for a while no worries. The Akuma Intake is a 2.75" 6061 Aluminum design. The initial install requires the bumper to be removed and the filters placed in the bumper area. Once it is installed, the body of the intake can be removed as one piece. The intakes have a symmetry by design, for performance and aesthetics. We are going with K/N filters at this time. If we can find a suitable replacement, I will entertain that option. The K/N filter media is very effective and the filters do not leave oil residue in the intake after 1000miles.

So why Akuma over the competition? The basic answer would be design(open radius bends, larger diameter piping, MAF placement), materials and customer service. We use USA made Aluminum and K/N filters. The engine bay couplers are Nomex, which is a better material than the silicone counterpart(higher heat tolerance, and a bit stiffer which aids in support). We will also offer a base calibration for Up Rev or Cobb(should there be any) users. Finally, we are easily accessible. If you have a question, you can speak with the designer or a technician that has helped on the design. So you know you will get any help you need.

The MAF is placed in the straightest section of airflow, therefore tunes very easily. The Z is nice in that you do not have to mod the MAF table, as I believe there should be 2 banks as the GTR has, but the tuning software provides for one table. However, this may be a function of the UpRev Tuning suite and be 100% correct(one table). You only have to modify one value in the tuning software, that provides a global effect to the fuel trims. You then modify the fuel target table to a desired fuel curve. The Fuel comp table(on the cars we have tested) does not need to be modified.

We have been a little slow on the release, and that is 100% my fault. I wanted to get 1000miles on the first set and take them off and see if there was any areas of concern...excessive wear, etc. I will have those off on Tuesday(possibly Monday if my wife lets me go into the shop...lol).
The next few sets will be finished up and shipped out. I want to try and get the first few sets to guys here and if they have access to a dyno that is really helpful. The other delay was the MAF sensor flanges. We got a few sets of the wrong size, so I needed to have that corrected before final welding. All of this will be sorted out and kits shipping this upcoming week.

I wanted to thank the community for the continued support. This truly helps us design a better product and keeps us in touch with the pulse of the community.

Regards,

John

Since Stillen is the industry standard(they have a good product) it makes sense to use it as a benchmark test... If someone has access to a dyno and has the Stillen G3, but does not want to buy a set, I can potentially send a test set out for 3rd party comparison, but they must be sent back after testing(assuming they do not want to buy them). We could go over the details off the thread...give the shop a call Tuesday or send me a PM during the week.

Dynos cost money as does the time to adjust the tune, how are you going to cover that cost for someone who has them both dyno'd back to back plus install time and tune time?

Aaaahh, yes. I reread how I wrote the offer. What we would do is give the intakes to the person doing the comparo at a very heavily discounted rate to offset the cost of the dyno runs and time invested. The intake install can be done by the end user, so there should be no shop cost to offset. If they chose not to keep the intakes, we could work together on a solution with the shop the dyno pulls would be done at to cover costs etc..

Hope that helps a bit.

Cheers,

John

That sounds very reasonable. I am interested as are a few others if you want to let us know what rates you are thinking about.

Again we are back to work on these intakes in order to ensure we have the BEST intakes on the market.

We realize the release of these intake have been long awaited and anticipated. But when it comes to engineering a product like this you can't just throw some metals together and call it a day.
We are now on our 3rd revision in order to squeeze everything we can out of these intakes. It is very important to keep improving the product you have and just as important for you guys to see the progress along the way.
We not only started this thread to gain some interest but also to show how the engineering of a product so simple looking can take so long. It requires a lot of testing and seeing what does an does not work. Its the small things that matter

We made some new revisions to these intakes which include the following
-More open radius bends
-2 inches shorter in overall length
-Longer straight tubing before the MAF's
-They will be offered mandrel bent with no welds!

In the picture below is all of the Rev Models..
Top-Rev1 (2.5")
Middle-Rev2 (2.75")
Bottom-Rev3 (2.75", with thicker walls for added durability)

LONGER TUBING BEFORE THE MAFS

glad to see the tweaks being worked out. what do these revisions improve?

All the improvements would most improve air flow. Zero welds means less turbulence, because the entire inside of the tube is smooth at a macromolecular level. Longer straight tubing reduces misreading at the MAF, and will deliver more accurate, precise voltage output, which prevents the ECU from tripping balls because the airflow changes. Straighter, longer tubing, again, reduces turbulence. Shorter overall length means less travel from filter to throttle body, lowering the resistance of the air to movement. It's easier to suck from a straw that's a foot long than 10 feet long (fun experiment, btw). I know what a bend radius is, but I'm not sure what "open radius bends" are. What I'm guessing is that the bends are less extreme, again smoothing airflow and reducing turbulence.

Basically speaking, smoother, more laminar airflow = faster moving, smoother, more consistent airflow. This means the MAF reads better and more accurately, and also provides a good intake charge into the plenum. All this means more horsepower across the band, although I'd imagine the biggest gains are at mid to high RPMs where faster moving air normally causes more problems especially with the stock intake tubing.

Of course, I'm only an engineering student, so these are the most likely improvements, but the actual engineer developing the intakes probably has more reasons which might also be more complicated.

I can't remember if welding or mandrel bending is cheaper overall.

Makes sense to me.

Please define 'tripping balls' at the engineering level.

Engineers are often said to be like this:

( Click to show/hide )

It is commonly joked about (and also proven to be true, to a degree) that engineers who produce something that is not perfect are tortured.

According to urbandictionary, this video is an accurate representation of "tripping balls" (not gonna lie this is pretty freaky):

( Click to show/hide )

So, I guess if you tried to define "tripping balls" at an engineering level, you'd arrive to the conclusion that it is some kind of painful, mindboggling experience. In other words, the MAF is confused and is subjected to watching that video over and over. It then produces something which doesn't make sense, which makes the ECU also trip balls, like watching that video while on shrooms or something. Would be a lot worse if it were a bad trip. lol

They do look better than Stillen G3's that's for sure.

Welding is cheaper, this is why Stillen is doing that. Mandrel bending is expensive, like you said:

XwChriswX · 07-20-2012, 01:51 AM

I just wanna know 3 things:

1. They will require NO cutting to the front dam correct?
2. What kind of filters will they use, Oiled/Dry?
3. When can I order the final revision!

Cafiax · 07-20-2012, 02:28 AM

Will these intakes have the AC line rub like the g3 does?
