I thought I saw a dual inlet airbox from gsrboy, but I think he was building a 3.5L ITB FI application.

I posed the dual intake question, my thinking was that once the box is sealed and the air is coming from both side's it can feed 3 horns at a time. for example the driver side intake path would direct air to the rear bank and the passenger side to the front bank. I'm not an engineer or have no back ground in engineering, so hopefully someone can offer positive comment's to help the topic.
I have seen most of itb set up's using the above air stream method, as in f1, jgtc.
Kakimoto used the oem intake location and a sealed intake box on their design.
I'm not sure how to measure the flow of air from the side's compared to the top ?

I live in Virginia and wonder if the 1TBs will pass state emission inspection? I suppose if they can in CA, then they should be good almost anywhere.

I think someone addressed this in other threads when they were developing an intake... They are in actuality just vents. The aero on the NSX doesn't allow much air to go through the vents that's why you see more of the Cai positioned near the rear wheel well. That's why the jgtc car utilize roof scoops to ry air because aerodynamically it streams the most air into the engine. I am by no means an engineer, that's just the info I gathered from reading the threads.
I also assume that the roof snorkel is the shortest air path to the ITB's.

Who said ITBs are legal in CA? Or are you saying you know how to make it pass visual?
I should stated, are 1TBs legal in California or that matter any US state? Hope that clears things up.

No it won't pass visual inspection. But if you really crazy about running ITBs that should not stop you as it doesn't take much to put it back to oem. Just keep the linkage synced. I'm also looking towards this setup as it's my long time dream (since my first s2000 actually). Aside from cost there is no offering for airbox to feed air from side scoops.
I've been looking at going ITB as well. We need to commission someone to build us an intake box.
Maybe Jeff@Carbon6 or Stephen (Sduff@Composites) can mold up something for us?
I really like the look of Kakimoto air box:

Looks like PhonyBoy may have a solution to air box -> http://honda-tech.com/acura-nsx-43/sweet-air-box-3187009/
It also looks like the setup is using a DF air filter.

NICE! Says custom made too...
Great Link, KSP ITB air box looks great, factory like appearance

Problem is that is photoshopped. IMO a proper ITB box needs to show the pipes.

My Plenum setup. Just need to get the trumpets set up inside the box.

wow ! Great job with the fabrication, I assume you made it all yourself. Can you explain why you went with a stepped intake box design from the fender to the ITB box?
gsrboy: that thing is a piece of artwork.
(So does that mean you're keeping your ITB setup?)

He's selling it to me.
No way I can do that by myself or anything close to it. That's actually a water to air intercooler connected to the plenum. I was going to do ITB turbo a while back but just haven't had time to pull it off yet.

Probably not, any news on the setup you were thinking about?
Are you willing to sell your supercharger?
I couldn't get questions answered, so at this point I'm more than happy to wait on your setup. If it happens, great, if it doesn't, I'll manage.
RYU: go away :biggrin:
For your setup? Are you kidding man?
That's like saying.. Am I willing to trade my 360 Modena for a Huayra!

This brings me back to when I visited you guys in SoCal 
Can't believe I got to see and experience those cars back to back!

Thought i'd chime in with an update on IAT's now that I have a scoop on my roof (The SOS).
With an ambient air temperature of 50 degree's outside, my IAT reading reached 77 at idle after sitting for 10 minutes warming up.
After about 3 miles of driving, the IAT was showing a 53 degree intake temperature. I am pretty happy with this for so little invested.
The ITB's are coming off my street car and moving to my N/A car with 11.8:1 compression. I'll let you know the results!
