If you want a good laugh, go back and read the first post in this thread.
With him "speaking to us", sometimes "emphatically" using bold print on occasion, as though to make sure that we don't "misunderstand" him.
Then he gets to the end and "cautions" us, breaks it down for us:
"Language often plays tricks on us — especially when language is used by product advertisers. "Ram air" sounds much more appealing than "resonant airbox." Nevertheless, it is airbox resonance that actually generates a significant power gain."
The complete quote is:
" Language often plays tricks on us — especially when language is used by product advertisers. "Ram air" sounds much more appealing than "resonant airbox." Nevertheless, it is airbox resonance that actually generates a significant power gain. At snowmobile speeds, ram air is just words."
Then under the hail of applause, and "nice writeup", etc. he "takes a bow." Then does an "encore" by copying significant parts of yet another article

Step 1: I think you will see an improvement in power with any aftermarket system, be it the Vararam, Blackwing, or whatever. It's not hard to improve upon the factory's quarter sized air hole. Lower the air intake restiction and you will see an increase in power.
Step 2. COLD air is the answer. Pick an air system that grabs the coldest air. Does the Vararam pick up colder air than the Blackwing? Probably.

Well this went down hill quick...
...again if someone wants to let me borrow a BlackWing (I am trying to buy a used one now with no success) I will post some hard comparative data.
Like:
IAT vs. speed difference
LTFT effects
WOT (PE) AFR effects
This subject is dear to my tuning heart and a problem I have been fighting for a while... I have a funny feeling that there will be little HP difference (after tuning to the same parameters) and the BlackWing would offer (as I have said before) a more linear MAF scale, easier to tune and maybe a more smooth throttle transition...

I cut a window in my shroud and my Blackwing also gets ambient air.

Cold is a relative term in these context. Cold air is ambient air and vice versa if that air is "colder" than under hood temps. There you go with absolute statements again.
Ram air forever!!!!!!

I just got an LC1 and plan to log as much data as I can over the next few weeks.

With an untouched tune after Vararam install (and 50ish miles of driving) my WOT (PE) AFRs went .6 to .8 point more lean... .8 being in the higher rpms.

SideStep this would be interesting and I would like to see the results. But for me there really is only one test that matters and that is trap speed and qtr mile ET's. The two comparisons that come to mind for me is EB's comparison with the blackwing which showed significant gains using the vararam, and Tracy's comparison between the bottom feeder CAI and the vararam. But like I said your test would be very interesting and could help people tune there vehicles better I would think.
300 you are a little off track I think. It is good to research things but the people that are telling you their results with the vararam have actually used the product they are not in any way going by their advertised claims. The reason some of us get aggressive when someone posts these scientific type arguments is we know from personal and practical experience that they are in error. I have read several articles on air box resonance but like I said before the vararam was designed to utilize cold air, high flow filter, and ram air. I don't think they hit upon a majical air box resonance frequency by accident. And if they tuned it this way on purpose they would advertise it.
So here is the thing, I tell people about the vararam because I have used them on two C5's, which I drag raced two-three times per week for close to 3 years. I know what it is capable of. I have seen posts of people who have put on the Summit LS1-LS6 conversion package and not received the gains people have gotten with the vararam. So anyway if you have not tried it you probably should I can assure you that you will probably delete your post. The reason I say this is after you use one and gain 3-4 tenths over the OEM box and 1-2 tenths over any other CAI on the market you will feel a little silly using a math equation to prove there is no ram air.

Theory has it that at zero kelvin individual molecules, atoms-all matter, exists as a big "blob" of uniform indistiguishable uniformity. Actually experiments have proven this to be true in our limited knowledge of the universe.
I hope you don't mind that I put that in lay-mans terms for you. I don't exactly have my scientific papers in front of me right now.

Yep, ram air is a myth.. one can obtain access to cold air but not under pressure. This has been discussed on this forum since 2/99. Thats why I went FI... lots of Ram air there... as my S/C setup rams air under 10 lbs of boost right into my engine any time I want it too.
