Lets actually say it does what it says and turns turbulent air into a "tornado" of air coming in your engine.
As soon as it hits the TB butterflys at non-WOT the air is just going to get turbulant again! Am I right or am I right?

this thing is a waste of $$$ , I find one thing funny though, at the mall they have what i call the "import perf store" they are selling the tornado thing for $65+ I wanted to rip the guy a new *** hole but ya know id get a harassment charge......

Personally I don't KNOW if it's junk or not (although I am skeptical like most others), but I'm open-minded enough to find out if they will fess one up for testing purposes.
I think it's a good item to debate.....I like debate.

This was posted not long ago by Mindgame...
A good friend of mine who use to work with Dale Eicke (famous pro stock head porter) did a test on the Tornado about a year ago. A group of guys in our dragster club got together and decided to chip in and buy one just to see what the hell it'd do. So we all pitched in a few bucks and ordered the thing... having it shipped to my buddies shop. Here's the e-mail I recieved on the tests.....
just did a very quick initial test of Tornado on
SuperFlow SF-600 flowbench
test was just on flowfixture mounted ontop of
digital Swirl-Tester ...no carb or air cleaner , test was
just to see effects of Tornado only
Results = immediately "ClockWise Swirl" was achieved
gradually raised test pressure in inches of water to
2.000" H2O where clockwise swirl maxed out my swirl meter's capacity at 16 to 18 inch/ounces of torque coming in at 2.00
thats 2.000" inches of water , swirl will be tremendous at
2.000" inches of Mercury Hg., beyond my test capabities
to measure any further increases in swirl -torque past
18 inch/ounces
quick initial flow restrictions with ONLY Tornado were NONE
no flow losses , CFM readings remained unchanged
next will begin flow testing with carb, air cleaner, intake manifold, head as total induction system
results to follow later tonight
_______________________________________
just finished more "Tornado" FlowBench tests
flowed Tornado on QJet and Holley 750 double-pumper
attached to Edelbrock Victor "E" SBC intake
on a GM #041x Super Stock max-ported head
Results=
absolutely "NO" difference measureable with
Tornado or without Tornado , when entire
induction system path was flow tested !
The overwhelming cylinder head's intake port
bias influenced Swirl-torque and orientation
(Clockwise or CounterClockwise)
...with or without Tornado in place made no
differences in swirl-torque or flow CFM
--------------------------------------------------
Next, removed cyl. head, intake manifold from
flowbench....then flowtested the carburetor
by itself to see if Tornado would create
measureable swirl
Results=
at most the Tornado created Clockwise swirl
approx. bouncing between ZERO and .20 inch/ounces
of swirl torque,..when measured flowing thru carb
I was pretty amazed when i 1st flowtested the
Tornado by itself on just the flowfixture
the amount of swirl torque was amazing !!!
it maxed-out my Swirl-Meter at only 2.000 inches of
H2O test pressure !
However when the entire induction system path was
flowtested with the Tornado as a "UNIT"
the extreme swirl-effect of the Tornado vanished,
completely unmeasurable on my flowbench !!
I increased flow test pressure to as much as
36.0 inches water..still no increase in any measureable
swirl induced by the TORNADO ...very disappointing !
i then had the idea to flowtest the Tornado just
on the carb by itself....i thought surely i would
see very large swirl readings with the Tornado .
Again, very disappointing, the swirl increases
were barely measureable , bouncing between
0.000 inch/ounces -to- 0.20 inch/ounces of swirl-torque
even if test pressure was increased all the way to
6.000 inches of water !
the carb bores, venturis, throttle-plates/butterflys
overwhelmingly canceled out Tornado's swirl !
even with carb butterfly all the way opened,
no changes in Tornado swirl effects.
if the carb itself is just about totally
"negating" the Tornado's swirl effects,
i can easily see why when the entire induction
path was tested , no recordable Tornado swirl effects
were seen .
Very disappointing 1st flow tests .
Will still try out Tornado on 3 dyno test engines
this coming weekend and 1/4 mile drag tests
and mileage test to follow in next weeks .
Will post results as they happen .
PS- about the only good thing i can say so far
is the Tornado did not cause a flow restriction
in all my tests . Flow CFM remained unchanged.

Thanks for the info Franker. I like those types of hard facts on paper. Holds more weight than "XXX is garbage".
I got an email from a Product and Planning Manager today offering to send me a tornado for testing purposes. Sorry but I just HAVE to know the results in front of my very own eyes. Once the dyno testing is done, I will make an effort to run several tanks of gas with it installed also to prove any gains/losses/no change at all.
If anyone else is remotely interested, small donations would be nice to help fund the dyno time. Either way, I'm testing it regardless of any help I get, and plan on posting the results here, good or bad. 
I am still skeptical like most of you, but I'll feel better knowing the facts on paper in front of me before I automatically assume the worst.

Cool! Be sure to keep good track of the results. And, if you don't have access to a web page server and would like to do a permanent write-up on this, I'll stick it on mine for you... just do the write-up and email it to me and I'll stick it up for you.

Sorry, i didn't take the time to read all yours posts but this is official: The air in the intake takes exactly 15/1000th's of a sec to make it from the air filter to the motor... tornado your trailor park but 15/1000 is fast enough for me and besides the TB would make it turbulent again anyway.... don't bother

How would you feel IF I actually just tested it on the dyno and this thing actually works?
"don't bother" - meaning, you don't wanna know and just want to sit back and be an armchair engineer/tester? ok, I won't tell you then.

on a camaro there is absolutely no chance the thing could produce more power anyway because it would have to be situated directly after the MAF sensor and BEFORE a bend in the elbow. this of course would stop any swirl that you may get with the tornado. the only f-body that would have any hope is a WS6 because of it in-line intake system but then of course it has to manuver thru the TB wher all swirl is again lost. im just happy some real science has finally proven that POS wrong instead of theories!
