I run a RN Racing "Twin Flow" open element system with twin conical filters plus drilled-out fog light shrouds and Z06 screens to let in more outside air. Certainly not a "cold air" intake- but I like the look and the sound improvement over stock.
BTW, I know EB20003 personally and he really knows C5's. I have no doubt that he saw real performance gains with the Vararam.
C5 aftermarket Air intakes are like cat-back exhaust systems. Beauty is in the eye of the beholder.

When I was a kid I had a silly straw. Fluid and air had no problem flowing through that. Of course I was not an engineer at the time so maybe I really was not able to drink through it after all.

BTW I saw your car at the recent Cruise in and it looks fantastic
On another note, my wife is holding you personally responsible for my becoming a Zaino Zealot
But alas, try as I might, I still cannot get my car to look as good as yours.

If anyone here does not believe that air can flow around corners and bends, just take a trip to downtown Chicago during the winter and you will experience this truism up close and personal

On a 95 degree day, after driving, has anyone taken the engine compartment temp to see how much of a difference there really is?? Not just a guess.
95 degree hot air is still hot air entering your engine, that's not "cold" air by any means. Yes, it's "not as hot" as your engine bay temp, but it's still 95 degrees...that's not "cold" air. Maybe the problem here is the word "cold" air. Cold air to me is 65 degrees and cooler consistantly.
By the way, I have the Vararam B2.
For the drag strip, .02,.03,.04 is a big deal. You're trying to win a race. Please, you drag racers, put into perspective for all of us just how much of a difference that really is. By a nose maybe.
If you aren't drag racing, any intake will work fine.
Chances are, the guy next to you just might be a better driver...no matter what intake you have

And the Great Ram/Cold Air Debate goes on. Too bad we don't have an Aerodynamics or Fluidics Engineer onboard to give some credence to this dialog. The only way to truly prove which is better is to install each system on the same car and driven on the same track by the same non-bias driver.

Also, does your manifold hold more air just because you are allowing more air into the engine...

Still plenty of space for air to get through, especially at high speed.

On my previous Vette I had the Breathless Vortex with a WCC air bridge. It worked well and the quality was good. Since then I've paid particular attention to the Callaway Honker. Having seen it in person I must say the quality appears to be as good as OEM. And according to a recent magazine test it works well,too. It also relocates the MAF near to the throttle body just as the C6 now does. Initially it may seem expensive but add up the individual pieces involving an intake and air bridge duct and the price is reasonable ($490). It will be my next mod.

I think I'm one of the oddballs here, no vararam, halltech or blackwing for me. My girlfriend got me a granatelli twin cone intake for my birthday. I really like it, nice SOTP increase and it looks really cool. All these systems are probably within 5 hp of each other and all are better than stock, just pick one.

Not true, if you provide ram air to the intake this will reduce the parasitic HP loss associated with the engine intake. The HP gains have nothing to do with compressibility. Sometimes we need to use plain old common sense to solve the problem. Do ram air setups on motorcycles and cars work, of course they do.

It was a highly respected science, and an alchemist could write his own ticket, back in the day.
Sir Isaac Newton started his career as an alchemist. And wrote extensively on the subject.
Of course Alchemy was and is, nothing more than bull$#!+, but the practitioners and believers liked to wax proud and show off their knowledge of this "science" to the "lay public".
Why do I bring this up????
Because most people here care as much about Fluid Mechanics as they do Alchemy.
You never did show us how the principles of fluid mechanics run counter to what the Vararam offers.
If it is violating the principles of fluid mechanics.............................ho w come it works?
And don't say the filter. If the ducts have such severe, significant, performance crippling kinks and restrictions in them as you seem to imply that they do, then why does the Vararam give the results that it gives?

This is a stock 02 Z06 with a Vararam. I have seen this car run deep in the 11's.

So, if an engine has to pull air from static, compared to air allready traveling at 60/100mph, which would you think makes the engine more VE (or the engine breathing easier). This, along with the colder ambient air, is why the Vararam makes it's best gains, proven over and over, at the drag strip. Now we may call this ram air, but I like the Parasitic Loss/ VE to actually describe what's happening. I have mapped stock and Vararam on HP Tuner, under the IAT, and Vararam for sure keeps the intake air much, much cooler.
(Z06) As my only power adder(Vararam w/K&N filter) I have several 120 MPH + traps, with the highest being at 123.61. In the cooler weather this system had such a multiplying effect, that I gained 1 - 2 tenths on others not running Vararam. Now that the summer temps are up, my traps have dropped to the 114 MPH range(90* + temps). But still, the Vararam has worked well for me with proven results.

When you become proficiant using HP Tuners you'll see what it does to the PCM. Also be advised that fluid dynamics is used every day in various industries. It's not a theory.
