Tornado Intake by NRF
New "Cool Air inatke" is put on the market in Japan.
Near 3000rpm to torque becomes thick, and town riding becomes very easy.
From the Nakamura racing factory (NRF), it is due to put on the market in February.
It is just going to test the grade of a water temperature rise. It goes up by about 3degrees(℃) (it is cold) at present.

It is designing so that the air which entered from before may whirl around unlike the other company.
Since a wall is not behind an entrance, a smooth air intake can be obtained.

J, I suppose the only way to assess the effectiveness would be to have a number of drivers drive the car both before and after, in a blind comparison test, and see if they can tell the difference. My guess is that such a mod would be a completely subjective thing and we would never be able to really tell other than to try it for ourselves. We have the same argument, 4 years later, as to whether or not aftermarket intakes of ANY kind work. Strange as it seems, nobody has even placed a vacuum gauge in the factory intake box to see if it really IS an impediment to airflow. Perhaps, since I have two factory intake boxes, should I become bored one day, I'll do it myself and see what readings I get.

that's two pieces of duct work... 99 percent of the people on the boards could make that from things in their attic
hell, you can even see the aluminum tape they used.

When people make prototypes they have to modify things so for all we know the end product could look much more professional. Or are you just looking for a snazzy sticker on the intake to make it look better?

I kind of like the design. it's clearly a very early development stage but the air path seems much more fluid than racing beats. air doesn't like right angle bends and the RB one is full of them.

J,... Strange as it seems, nobody has even placed a vacuum gauge in the factory intake box to see if it really IS an impediment to airflow. Perhaps, since I have two factory intake boxes, should I become bored one day, I'll do it myself and see what readings I get.
If there is any benefit to these type boxes, pressure wise, IMO it likely would only become evident > 90mph where some small 'ram' effect would be "possible" (not guaranteed). I thought what might work would be a large bladder taking up the space behind the bumper. With the intake duct acting to pressurize a bladder it would provide a large enough quanity of pressurized air for the engine intake box to feed from. Too much work, but fun to think about. But I have too much time on my hands, obviously.

On the face of it, I like Jyariten idea.... and having a deeper box could be better, air flow testing would be needed to prove it out however. What seems reasonable, sometimes isn't or isn't worththe extra trouble. But I applaud you for the effort. And to those that say it looks like Home Depot, etc., so what? Any inventor starts with a mock up or for one offs, it may be the final that looks like it was made of cardboard or whatever.
But if it works enough to try out, who cares? If it can't be seen anyway, what's the problem? Bling/label envy or what? And I'm sure Jyariten had way.. way.. way.. more fun and reward from doing it his way than buying a Revi... which doesn't do much either...really

Spin, I am sorry as I had no idea you already performed this task. That was awesome and thanks for sharing your observations.
Guilty, myself, on the "Home Depot" variety comments. I was just poking a little fun at J and I am glad he took it in stride. Then again, I have endured my own brand of harrassment from others just fine and my stuff is still out there for others to scrutinize. Perhaps J could have his product injection-molded, eventually.

Jyariten, this picture is awesome. Show you really put some thought into the design. This roundness should put a good swirl into the airflow, like you said a Tornado! Why do you think that is a good thing BTW?
Will the final product be made of plastic/carbon fiber/? Cost?

Spin, thank you.
I think that it finally becomes black Colgate finish by FRP.
The price is planning about 25000 yen in Japanese yen.
+ Sipping 3500 Yen and Task .. ww

you'd be surprised at what asian people can do with shitty looking stuff, i couldn't believe my eyes in thailand, they put really wierd **** in their car that you guys would probably consider as "rice" "stupid" "shitty" but........they do go fast @.@ like home made turbo kits with F-con EMS for the rx8......idk how they do it -..-
