MG MGB Technical - Anyone tried Spiral Max?

I stumbled across this web-site for a gadget you stick in your air filter to swirl the air around and it piqued my interest: http://www.spiralmax.com/
It also seems a little too good to be true... Anybody have any opinions/experience with this thing?

Tony,
As you said "sounds too good to be true" and probably is.
I am surprised it is still around. I came across it a few years ago on another board and the item was old then.
So far as I am aware it is a waste of money.
The range of "improvements" are interesting 05 way up to 35%, whoa! That is some improvement.

Now if this thing really did work GM, Ford and everyone else would have latched onto it years ago.

BTW though if you do feel adventurous enough to fit one please post whetever you discover here so the rest of us can read it too.

Cheers, Pete.

Did anyone note that the VA Tech article thanks SpiralMax for their support but doesn't mention anywhere that the device is in use on their bike?
It's true that in some applications such as the GM vortec design, swirl is an important factor. However in other apps, such as tunnel ram intakes, and some throttle body injection systems, swirl has a negative impact and contributes to inlet charge reversion and fuel puddling.
I'm just an undereducated engineer who might be missing some of the finer points relating to the Laws of Thermodynamics, but I don't see how swirling the incoming charge across an 89-93 Ford mass air flow FI inlet would produce the exact same beneficience when impressed across the earlier 87-88 speed density sensor... by design, the speed density system actually reacts adversly to improvements in airflow because the increased airflow is invisible to the fuel management system resulting in an uncorrectable lean condition.
HOWEVER....
It's a well known fact that nearly every one of those miracle mileage improvers DO WORK, as their warranties expressly imply. Simply follow the installation and product use instructions to the letter:
INSTALL PRODUCT. MODIFY YOUR DRIVING HABITS AS FOLLOWS: NO JACKRABBIT STARTS, NO EXTENDED IDLING, REDUCE YOUR CRUISING SPEED 5 MPH, DRIVE LIKE THERE IS AN EGG BETWEEN YOUR FOOT AND THE THROTTLE..... ETC....
AND IN CLOSING
I'd like to take this opportunity to announce my new, patented miracle GASMYZER, the ONLY product on the market that YOU need on ALL of your vehicles, boats, aircraft and construction equipment. One size fits all, use 2 for V8 applications. Send $29.95 to ME at MY ADDRESS. Act now and you will get TWO for the price of ONE!!! Results guaranteed!!!!
