Akuma Motorports 370z Intake

'10Anamoly

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

slynx

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

370Z Purist

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.

TonyBPD

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: ░░░░░░░░░░░░▄▄

Engineers are often said to be like this:


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):


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

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!

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

370z purist..... That video freaks me the f*** out. But i'm very fond of your explanation on how the MAF sensors "trip balls" hahah

They will be K&N Oiled filters
The only modification needed will be to the front bumper beam where the piping goes through you will just need to open those holes up a little
I will post up as soon as we are taking payments

AkumaMS

370Z Purist explained the changes quite well. The overall aesthetic is improved as well.

Mandrel bending is nice because it eliminates any seams, smooths the path of the airflow(with the aluminum, the seams are so tight that this is only a mild improvement, if any), and makes for a more appealing product to some. Actually, it will be a little cheaper for me to have them mandrel bent in quantity, then fab each kit on my own. For now I will be getting a few sets done here then I will have a place mandrel bend a run for me. I like to have a few sets out there before they become a stocking item. That way if there is any issues or revisions required, they can be addressed before final run. The quality will be there for both.

We are using a K/N filter at this time, and they have a small amount of oil in the filter, but it does not go into the piping and I do not suggest oiling the filter any more after purchase.

The intake does require trimming the front plastic area. It will require the same install as the Stillen unit. We will have instructions up very soon. the trimming is minor, and does not have a negative effect on the front end. Our car is tracked very hard and daily driven, and there has been no cause for concern.

The piping will go over the AC lines, however there is a fair amount of play in the fitment, and we will provide a piece of silicone to protect the AC lines. After 1500miles, the first set has shown no signs of wear.

I hope this helps a bit. I will get you final pics in an hour or two, I have to finish welding. Pics to follow.

Cheers,
John

I don't know if this is something that you guys would want to do, but I have Stillen intakes right now with a full exhaust. I'm gonna be tuning the car soon, and I would be willing to put your intakes on and do another dyno run after everything is tuned up to get a comparison with full exhaust. If the numbers are good I would keep them and sell my stillens. You guys can pm me if you're interested!

I like the use of the word "trimming" to describe what has to be done to install these intakes as well as the G3's. Using the word cutting is a bit extreme and scares people. All it really requires is shaving a few millimeters of plastic and is done in about 10 seconds.

The intake is looking mighty good guys, real nice work Def like the non welded look
