OK before i state this i know there are going to be quite a few people who state, "if a little faned peice of metal would increase performace and mpg then cadillac would of installed them at the factory." Well guess what they didnt and it really works. My boss at my one job bought a new H3 Hummer installed it and is getting an aditional 2 mpg as for "performace increases" that im not sure on. Before you ask what does he know about cars? he has owned a garage in West Homestead for over 30 years. He has restored several cars including a 70's Impala, 56 T-Bird, 50's Plymouth etc etc etc. I know he convinced me to go and pick one up for my ETC will probably be getting it today because my led foot and 15.2 MPG aint cutting it.

I hate to burst any bubbles but, if the tornado does cause an increase in performance and fuel economy it will have defied the laws of physics.

Placing that in the air intake will cause turbulence that is certain, it will also reduce the volume of flow as it will be a slight restriction. Since we are talking about a normally aspirated intake as opposed to forced induction, the restriction may actually reduce performance. Also, it is questionable as to whether the turbulence is a benefit in an intake system.

I hope it doesn't cost you much to purchase.

you might see an increase in mpg, but thats because its restricting air, which requires less fuel, which also kills 'performance' so as stated, you cant have both without defying the laws of physics.

Well, I can tell you from personal experience that the Tornado will not increase your performance. At my school, we tried one out using multiple vehicles including a Celica GTS, Civic SI, '04 GTO, 1999 Z28 Camaro, and 1994 Z28 Camaro just to name a few. Each time, the dynojet read the exact same HP and TQ reading with and without it. The concept behind the Tornado is sound, but not possible where it is mounted. Once that swirl hits the various plenums inside the intake manifold it's broken down anyway, not to mention that if you have a MAF sensor with a screen, then it's completely useless since the screen is there specifically to "straighten" the airflow as it hits the MAF sensor wire.

In order to properly road test a car before and after the install of a Tornado, you have to have someone drive the car who doesn't knwo it's in there. Otherwise you'll end up with the same situation as the K&N filter, where it "feel" faster, or "sounds" more powerful or what have you. The Psychological aspect regarding what you see, and what you think you see can easily scew the data you get from a modification such as this. It's best to test it without the owner of the vehicle knowing. Keep in mind though, that this is just my opinion, although it just so happens to be shared by many other here. Good luck with the hunk of metal in your intake.

at 70 bucks for the unit how long would it take you to recoup the cost?

this is not unlike what some doctors call the "placebo" effect , i bet if i measured his throttle useage before and after the unit was installed i could tell you that he is actually "babying" the hummer without knowing he is doing it ....

any "swirl" effect is lost after the air passes by the throttle plates , and intake manifold , not to mention the valves ...

a lower restriction air filter will net you a bigger gain on MPG than the torando , while i dont recomend the k&n and copy cat filters , the cost savings over buying a filter every few thousand miles and mpg gain make it more worthwhile than something i can have Kev make for me in his spare time at work (right proud unoin tinner buddy?)

im just basing my finding on what i was told and he is a very reputable source so i trust in his findings and he is no light foot he enjoys trying to climb anythign he can with his truck

Not only does the Tornado work, but if you combine it with Slick-50, fuel line magnets, a K&N air filter, the Turbonator, Z-Max, DuraLube, Prolong, the Fish carburetor, and Splitfire spark plugs, you will get such awesome mileage that the engine will actually MAKE gas and you'll have to drain all the excess fuel out of the tank when it gets overfull! (thanks to our old friend Rob for that last reference)

As has already been mentioned, the MAF screen will take most of the turbulence right back out of the air flow, and even if it didn't, the throttle blade would do it, and even if that didn't do it, the shape of the intake would. The Tornado is as useless as mammary glands on a billy goat unless you're the owner of the company that sells them. Think it through. Try real hard. If you want to put more air through the engine, install a high-flow exhaust system and one of eldorado1's 80mm throttle bodies. The Tornado isn't going to get you anything but ridicule.

Why don't you put that money somewhere useful, like in a savings account or a college fund instead and stop trying to re-engineer something that was designed by lots of people much more knowledgeable with test equipment a little more sophisticated and accurate than some dude with a Hummer who likes to climb rocks. If your car is getting crappy gas mileage, you have to fix whatever problem is causing it, and that may very well come down to your driving habits or how much air is in your tires.

I am not joining any any type of abuse here, but realistically your boss or whoever he is could increase his mpg by 2mpg just by changing his driving habits. The fact that he installed this device to improve his mileage may have subconciously caused him to drive in a different way just to see if he could increase his mpg.

There is no scientific study based on ONE person. Just because it may have "worked" on one vehicle doesn't mean it will work on all, or for that matter another one just like his. If he drove it like a maniac before and now he's trying to get better mileage, as I said, just changing the way he drives could give him better than a 2 mpg change.

Not only that but I question the way most people calculate their mpg. Is he using the trip odometer and the amount of gas he is putting in or is he just watching the little trip computer that tells him his mileage. The direction of the wind could affect his mileage!

You beat me to it. :histeric:

CadillactETC1997,
If your boss owned a garage, one would think he knows better. Either he is very naive and gullable, or he is pulling your leg and you took the bait.

I haven't looked but maybe there is a ebay sell on them, from what I can tell once most people have came to visite this site, they might be selling theirs for some kind of refund. Not that any forum member will admit it. I considered it but after searching this forum decided against it. It's your money do what you feel regardless of what other's say. Experience is the best teacher.

And just to think that there are ads on this very site promoting the 'Tornado.'

I am all for trying it for yourself, yes, experience is the best teacher.
I just wouldn't recommend it to anyone.

I'll admit, I actually had tested it on my 97 Eldo long ago. I drove 2 weeks, and did indeed pick up about 1 mpg. However, I also went to the track, did 4 runs wi it, 3 runs without it. The runs wih it were all 15.x usually .1 or .2... The runs without were all 14.8 .9 So, the Tornado saves gas, steals power. Enjoy. Mock me for testing it, but I experimented with a lot of things in the search for power. Nitrous was my biggest gain and problem. The tornado was relatively harmless. :p

I'd have to agree with the statement that the Tornado is "The tornado was relatively harmless." It's mass isn't enough to choke an engine into not running, yet it is mass, equaling an obstruction. I've addressed this subject here before and the only way a "swirll" could be effective is to build it right into the intake tract runner, and end right at the back of the intake valve. This has been tested over the years and shown to be benificial to power, yet prohibitive to production. The cost of producing an intake manifold of this type would be astronomical and would not guarantee measurable results on a production basis.
The Tornado just turns out to be one of those automotive kitsch items that attracts attention enough to be viable for producing revenue, period.
cadillacELDO1997, have you tried this Tornado along with the addition of acetone as you have propitiated in earlier posts? Nuff said.

EXACTLY - every test needs a Control as well as the Experiment. Otherwise, the result of the test is invalid and subject to the subjectiveness of the tester. Better yet, it's better that the tester doesn't even know what he's testing. This is called a Double Blind Control. The drug industry as well as many, many other industries use this to validate the results of their tests.

Did we not all learn this back in frickin' Grade School??!??!?!
