Never mistake ARC intake with a short ram. 
the ARC intake is designed so that air will resonate inside the box, and when that happens, air compress itself, increase pressure and density, Yes, it is kinda like boost, but a really low one. I forget what this is called, but look up in the gas dynamic books, u will find it. Go measure the dimension of the box, it's in harmanic with air's natual resonate wavelength. I did use heat insulator on the back side of the box. Also look at the chamber design, it makes sure that there is enough air stored there, thus improve throatle response. I do admit the intake is a pita to put in, BUT it works great!
talking about short ram, ram air effects won't happen on the ground, period. ram air effect means that air slows down after shock wave , and with a carefully shaped chamber, air can be compressed and cooled down at the exit, it won't happen without shock wave, which does not come out untill it reaches the speed of sound. How the hell can u drive that fast
short ram intake is no where near the ARC's design.
the tanabe exhaust will go for an ARC single,
that's after my toda cams of course.
ARC all the way baby

Let's use some logic please, hot air=less hp? Correct? Where is your intake with an open filter in an engine bay going to be drawing most of it's air from?
OWNED? I think not!

I cant help but giggle at the concept... sounds absurd to me, albiet interesting.
Yeah...
Yeah...
as long as there is a harmanic condition, interference will happen. there what the box is for.

Wow and you believe that? I have a bridge to sell you in brooklyn, if you want, dirt cheap. Listen how come ARC can't produce any dyno numbers to back up your claim? How come ARC themselves can't guarantee any gains? FYI, I was offered the ARC intake for free about 3 years ago to promote it. Guess what? I asked them a simple question about if I should gain any hp and they couldn't answer it.

I hate to break your bubble but turbo_pwr is correct. He has been around the car long enough to experience just about everything that goes along with it.
The effect that you are trying to explain is the Venturi effect you can see a good explaination and diagram here:
http://www.ce.utexas.edu/prof/KINNAS/319LA...ri/venturi.html
You are begining to see more and more intakes with Venturi chambers the AEM V2 and the J's are both perfect examples of this. Some tuners are also making arms for the Mugen intake which includes a resonant chamber.
In sort you do see some benefit from this approach. However, I have not seen this effect yield more horsepower rather it has generally shifted the peak of the HP curve down slightly to lower RPM where it is more valuable for our car.
BUT in order to truely benefit from this effect it would help greatly to have colder air entering the intake chamber. Which on the ARC I am afraid is not happening. One of the rad plates like the GD may help but if it did come with some sort of heat shield I would strongly suggest installing it.
Also please fix that exhaust. Thanks.

yeah, for the most part that is correct, Air has to be moving for this intake to make power, when you dyno a car don't you put a fan right in front of the front bumper so air cools the radiator. Well the air is also being blown right into a CAI that hangs down low, so go figure why they make numbers on the dyno, sit one of those fans right in front of the ARC air box and it will produce you the same numbers. Either way, you are all talking about gains from simple bolt ons for the S2000 which are pretty much minimal to say the least.

Ironically how when someone posts their ride up in the gallery, it turns messy when the owners hear negative remarks. Seriously, if you aren't prepared for what's to come ... Don't publicate your ride.
Everyone is entitled to their own opinion, whether you like it or not. You're not gonna expect everyone to have a same opinion as you. I'll take the advice given with a grain of salt instead of believing everything a manufacturer has to say about their product.
Remember, those manufacturers are trying to sell you something. Worthy advice given on here isn't gonna benefit anyone but yourself. I personally say lose those stickers, unless you're getting sponsored for your efforts, it's absolutely ruins the car and makes you a stereotypical statistic.
