Definitely... The ideal setup would have the air charge coming from the coolest place possible, which would be as far outside that engine bay as you can get. This is why blackbenzz's intake setup most likely works better than anything currently being offered by any of the tuners.

cons: the diameter of the piping has to decrease to fit thru to the front. the cost of fabricating this setup was quoted to me at about 850$ while the setup with shorter intakes is 1/3 of that price made in the same place.

To get the benefits of a true cold air intake the filter has to make it out front somehow. Maybe at the fog lights dual setup? Or replacing the light like blackbenz did. The pro is lots of hp being lost with your current setups. The con is sacrificing looks of all that pretty carbon fiber.

To answer the OP, the reason the whine is gets louder under load is A: your opening the throttle and letting more air in which creates compression of air, hence this makes the rotors hot and they mesh more. B: The sound carries back through the throttle and air filter which almost amplifies the sound. When you change to a cold cone intake the sound is louder, its down to the design of the cone and the sound insulating properties.

I've noticed that if you get the car to upshift to second or third gear at a slow speed and slowly bear down into the throttle so as not to get the car to downshift, the symphonic whine begins to magnify under engine load. Music to my ears!

The Maggie'd C6 Vette whine is extremely prominent & NONE have restrictive styled airboxes, all the E55/C32's w/VERY loud whine like the Maggie's have modded the OEM airbox, airbox is obviously acting like a muffler. Placing the Airfilter out front away from the TB intake is key here in making prominent whine..
I've modded multi N/A engines over the years as well, installing CAI w/Airfilter away from Throttle-Body intake will have a similar effect whistling sucking noise. (although nothing as loud as a Blower)
Your link above is for Centrifugal blowers, a bit different than Positive Displacement blowers in the E55/C32 in question, they spin way faster & higher in RPM band & the whine is different almost sounds like an Electric car on steroids.. The Vette Centrifugal versions sound like garbage disposals w/silverware stuck in it @ idle
If you click the Twin-Screw Supercharger link this is @ the end of page....

The compressed air exiting the discharge outlet creates a whine or whistle that must be subdued with noise suppression techniques.

I found this on the net and though the filters look nasty and I wouldn't utilize the UFO-looking filter covers, the polished aluminum tubing and heat shields would work and should connect right up to some K&Ns. This is what I was considering having fabricated and for the price they are asking, I could get it made and ceramic coated. The website layout looks remarkably similar to Jerry's!

An intakes purpose is to suck in as much air as possible. I would take a higher volume of air even if its slightly hotter rather then a less volume of air that is only slightly cooler. After the air enters the motor and reaches the intake air temp sensor it will get heated up anyways. Sure, a cold air intake will make a difference. But IMO it is the job of the intercooler, heat exchanger, IC pump to cool down the charge temp. Not an Intake.
What I am trying to say is Let the intake does it's job. That is to draw in as much volume of air as possible. Let the intercooler do it's job lowering charge temp. Just my 2 cents.

I think you fail to notice that when the car is moving the air flow over the car will also have some sort of cooling effect on the paint.

That's why I said parked in the sun.
MB Engineers probably think past 6 years. I've seen cars as early as 10 years old start that have hood fade.

Oh btw here's the video of it from inside. From outside I heard it rather well when I had my buddy do a fly by.
