It still looks homemade. So how much is the price in US... $400? It looks like it was something that was made from some stuff found in home depot and a cheap immitation of the Revi. If it uses those materials, no one will buy it.

 

What is the point of having the airflow swirl around before it hits the filter.

Isn't it just going to get disrupted and go back to how it normally would flow after the filter?

 

he's baaaaaaaaaaack

 

Kinda like a bad dream!

Better get the turbo post counter all warmed up and ready to go.

 

wouldnt the screen(s)....if you have them, just straighten the air .....

 

Ahhh.... he said it was a prototype and the final would be black Colgate finish by FRP

 

also it would be 25,000 yen. thats $250. +$35s/h.

the duct is huge though. wouldnt it interfere with the radiator?

 

This TornadoIntake is the first step of an Intake system.

I consider an air filter box to be a silencer.
The air intake chamber of RX-8 exists near a throttle.
However, I think that its accelerator response will also improve if this air intake chamber thinks that it is small one and this is enlarged. Moreover, I think that intake manifold pressure will also be increased by this (dynamic effect).

Although it is expected that the filling efficiency of air increases by TornadoIntake although intake manifold pressure has RX-8 [ 0.05-about ],It is checking that pure 0.05 is going up to about 0.1 (it measures in the intake manifold pressure meter of Defi).

Intake Pipe to an air filter box is the same layout as Normal.
Although 80 phi etc. tried many things, since the thickness of Intake Pipe did not have the good rise of 7000rpm or higher, it is set to 100 phi now.

 

Ja, it looks like OD's hand made dryer hose and cardboard shoebox on the end.

 

im working on a new ram air.... ill verify it with a leaf blower on the dyno...

but it will be a racing design also.. sooo expect summer 2008, (if it works), same "tornado" concept...

except think along the lines of the inside the barrel in a gun..

"not the tornado fuel saver" hahahahaha

 

boy i bet somebody laundry room is nice and cozy with all that warm air coming from the dryer!!

 

My dad told me swirled airflow will make the engine run smoother. but i dont remember how it could be smoother.

 

Swirling air is suppose to atomize fuel better. A few years ago honda had a civic called the HX. It swirled the air at cruising speeds by allowing 1 intake valve to open normal while the other opened a 1/4 or so. This made the air swirl in the combustion chamber it's self and the car did get better gas mileage then a V-tec for about 5 hp less. At WOT the V-tec-e on the HX would lock the second valve on the same lobe as the first. That should work the best.
Now if you try to swirl air before the throttle body it might help but. The air has a really long way to travel. It has to get passed the throttle body (witch can stop the spin) then break up into other pipes bend and wrap around, then go into the combustion chamber and get fuel and still swirl it.
Only real way i can think to test this is by recording the air speed it's self before and after from various locations on the intake. I wouldnt expect mush if any gain in hp.

 

Still waiting for this to come out..Not the homemade one. Jyariten.. Where can we purchase this when it does come out? And any exact date as to when it is coming out? Thanks.

 

Airflow does not work like that in the intake. Laminar flow is the goal but you don't have to swirl the air to get laminar flow. I remember the stupid tornado infomercials where the guy used 2 water bottles to show that swirling the water allowed the water from the top bottle to flow faster into the bottom bottle than no swirl. This was a crap display as the swirl creates a void in the center. With a closed experiment like that 2 things are getting displaced, not one. Air has to move to the top bottle. Water flows faster when swriled because the air in the bottom bottle can now move unimpeded to the top. If you take just one bottle full of water and turn it upside down, it's the same experiment. It just makes a mess. Drill an equally large hole in the top of the bottle instead of swirling it and suddenly the flow is fast again. It's crap.

As was pointed out, air does not continue swirling through the filter. Swirling it after the filter means more of it is concentrated towards the outside walls and less so towards the middle of the pipe. This is effectively making your intake smaller and hurting flow. This is a bad idea and it doesn't work. If you look at "tumble generators" such as those in Subaru intakes, air tumbles. It doesn't swirl. Air swirling into a cylinder is a different matter altogether and it's still a different direction than swirling it in the intake in this manner.

In a carburated system, the point of swirling air like this may be benefical to helping fuel atomization although dyno testing proved on a 1st gen RX-7 that it actually lost power so go figure!

On the RX-8, swirling air in this manner is the result of a guess based by those who have never done any airflow testing and also by listening to the propaganda of every other air swirling product out there that doesn't work.

 

I think Rotary God just gave the middle finger to the NRF tornado... I'm assuming that's a +1 for that Racing Beat air flow part huh?

 

How much is the revi intake system and where can i get it? Any one selling 2nd hand?

 

Wow..His first post and it's definantly in the wrong area...Dude..You don't post looking for other people's products when someone is talking about another intake duct.. -_-;; and we're talking about intake ducts..not airboxes or the system as a whole (persay) you should read next time before posting...

If anyone is planning a move from stock to any aftermarket intake mod, can I please have some before and after data so I can look at (and post) the mod's affect on long term fuel trim (better known as MAF calibration)?
