Tornado Fuel Saver?

The principle of operation is in the mixture of fuel and air. Fuel injection does not permit a pre-mix prior to combustion. The cyclone is the air duct prior to the manifold or plenum chamber. The chamber distorts the flow in order to route the air on demand to each cylinder and by design kills the cyclone. In so doing it has been rendered counter productive and therefore of no benefit.

If your injectors are clean and the air path is not obstructed the only benefit is to the gas station because of increase in sales. And the inventor of this scam.

I work in a garage, and I get asked this all the time. It doesnt work. Its all a mind game, it creates a different sound and your mind automatically thinks more power. About 95% of the prodcts out there that "will save you money on gas" are pure and utter BS. Like the magnets over the fuel line saying how it aligns the ions and helps the gas burn better or whatnot, Its a hoax. The best way to increase you fuel saving abilties, is to drive a completly maintained vehicle. A healty vehicle runs better and takes less fuel. A sick vehicle takes more fuel to get the same result. Keeping you oil fresh, your vehicle tuned up, leaks under control, and fluids healthy, the engine will not have to work as hard and you will save fuel.

As for the Tornado, I have heard that all it does is change the pitch of the air going into the engine, it makes a throater sound. I did that too, and it cost me the time of cutting some holes in the side of my air box (where the air goes into the filter, not where the air goes into the engine) and it made the same nosie. I know its a hoax.

If your truck is only getting 6 mpg with 2:38 gears, there's something SERIOUSLY wrong with it! I would verify that high rear end ratio and make sure that's what you've got; it sounds very unlikely that with a rear axle that high would get such poor mileage on the highway in overdrive. I think you've probably got 3:73, 3:90 or lower gears in there, in which case you might try something a little higher, like 3:50 or even 3:23.

By all accounts the Tornado does nothing for mileage; the only people making money with it are the people who sell it!

I've used them and they are junk on electronically controlled vehicles. Your computer just compensates.

If you Chevy is carberated, it should do wonders. If it is fuel injected, it should help, but probably not.

But it sounds to me that you'd be good just getting a tune up, using an in-tank fuel injector or carberator cleaner and a new air filter. Your Chevy should be doing better than 6mpg with proper maintenance, not gadgets.

Garbage. Independant tests show either no improvement, of slightly worse mileage. Anything that restricts the airflow os not a good idea. Don't worry about the so-called "dyno proof" - a dynomometer can easily be set up to tell you anything you want it to.

they do nothing at all. If they worked, they would be put on cars stock. Do you think the brightest minds in the auto industry just magically overlooked it? No.

all they do is restrict air flow and thats it. Total waste of money and they dont do anything.

I saw a test of these on TV. I think car and driver did it. Whoevr did the test said that they did not work at all and did nothing. MY friend put a throttle body spacer on his civic which is kind of similar and it just made the car run like crap

I had one on my 97 Ram,it did nothing for it.Waste of money.

I got better milage from the K&N filter i put on.

Just remember.....everything works on tv.

I had 1 and did get a few more mpg

Independant tests prove that it does not work save your money.
