Does tornado fuel saver work??

I have an 86 f350 dually eith a 7.5 liter gasoline. I know it is a big motor and truck, but I am looking for something to help on gas mileage. i get about 8 mpg now. I saw something on the tornado fuel saver but I was wondering if it is worth the investment.

save your money and get a good k&n filter. also do a good tune up plugs,wires, cap/rotor. i assume this has a carb. clean up the carb, adjust choke, idle mixture & speed,timing, tire pressure. make sure the fan clutch works. that tornado this is a scam you could fill your tank for the same price.

Just so you know. I'm also trying to increase MPG . But the EPA has found NO aditives or aids that do much or any thing that increses MPG, They recomend a good tune, regular mant, and better driveing habits. and the last is the most important. I was diving a 92 f-350 460. and it got 10, my advice, which I would follow my self if I had the cash would be to go 6L diesel, seems the best of both towing power and fuel economy

I would not use a K and N filter, there are better setups out there. On another forum which i post on, a person had a construction company, and would spend approx 1000 dollars in air filters a month for his fleet. He tried K and N and sent in an oil analysis before and after the change. Silicon levels ( dirt ) in the oil almost thripled. Tymar makes a nice intake. Is your truck carbed or injected? My memory is a little fuzzy on when ford switch, i have heard 86 and 87 both. If it is carbed, maybe get a better carb, such as a edelbrock 750. I know this sounds strange to put a larger carb on your engine, but with the use of a larger carb, you are not opening your secondaries, only primaries, thus saving gas. Plus if you get a cold air intake, and throw on dual exhaust with headers, you should expect better MPG. Also a good truck cam would not hurt. The easier the motor can breath, the better fuel milage you will get. As for the exhaust, if you decide to put on duals, have the installer install x-pipes. For then you can run dual 2.5 inch pipes and still have tons of low end torque. The reason for this is exhaust scavenging. Here is the easiest way i know on how to explain this. When a semi is going down the road, there is higher pressure in front of him and lower in the back. When your exhaust valve opens shouves air out, it goes down the pipe, then by the time the next cylender blows out the exhaust, there is a low pressure area right where the exhaust valve is making air come out easier, more torque and engine power on low end. Well with larger pipes, more volume, so less pressure, making better top end power and better MPG, no low end torque. With the x pipe, it makes 2.5 inch pipes scavenge like they are 1 7/8 pipe, best of both worlds. Good low end torque, good gas milage, good high end for passing power. The RV cam will be open longer than the stock cam, making the cylenders breath better, making more power, and with more power for the same fuel, equals better MPG. Hope this helps.

thank you all

on two different vehicles i have used the tornado and gave both of them saved on fuel and pep

I found a video, see www.youtube.com/watch?v=bWFvBG6CUHk (http://www.youtube.com/watch?v=bWFvBG6CUHk)

The air is metered by the MAF/IACT sensors, the ECU/PCU controls the fuel pluse for the injectors!

It might work better on a old school car, were the Air/fuel mix is in the carb.

The Tornado is nonsense. It's a direct sales gimmick, which does not work. It is a re-hash of an older idea. 30 years ago, an almost identical item, sold under that brand name "Swarup" was sold. It also was proven not to work.

These products do not work because a swirl or turbulence is not required to atomize fuel. Theoretically, too much turbulence is detrimental to carburetor venturi function, imo.

Another issue is the presence of throttle blades. Even if turbulence is helpful int he intake tract, throttle blades would eliminate it.

Turbulence is valuable as the intake charge goes into the combustion chamber, but in a specific way. Cylinder heads and combustion chambers are all equipped with shapes and features to achieve desirable turbulence. Imo, a primitive device placed up by the air filter will make no difference here.

K&N advertises that their air filters provide the same benefits (mileage and power) by, in part, reducing turbulence in the incoming air, just the opposite principle as the Tornado.

hello magic rat and daniel satur the tornado worked with our vehicles were new

I'll go along with MagicRat. It is a total scam.

So u calling me a lier davescort97 and until u try it davescort97 u shouldnt knock it, i have had it in two new vehicles.

Nobody is calling you a liar. But personal opinion does not mean much in an objective sense. If you say it has improved things, let's see some numbers.
How much faster is your car? Have you done some acceleration runs for comparison?
How much has your mileage improved?

There is much evidence, both in terms of engineering theory and in real-world results to say this product is a scam. Based on that evidence, davescort does not need to try it. Others have already done so and objectively reported on it. So, if you believe it works, please cite other websites or objective research information to back you up, before accusing us of calling you names. :)

i am giving my opinion i am allowed to do that and as it was .there was some difference special with the 4clynder we had a v8 u can either take or leave it but if u dont try u wont know will uthat is my opinion.

You are more than welcome to give your opinion on this forum. But the fact of the matter is, seat-of-the-pants testing means very little to us. To prove your point, you'd need to provide before and after mileage averages, even dyno results. Without this, I agree with the above posters arguing against it helping anything.

Now I'd like to give my opinion as to why. The tornado is a restriction in the air intake system. Turbulence does have benefits like MagicRat was stating above. A turbulent airflow has less friction against surfaces as compared to a laminar airflow. But the distance the air travels between where the device is installed and the throttle plate would create a minimal difference. The tornado takes up space in your air intake system, reducing the maximum throughput of it. You won't notice this at low RPMs, but if you went WOT, you likely will. The device has angled blades which, when the air strikes them, slows the air down - therefore, it is counter productive.

I am no scientist, but I am a pilot and have been trained for the last 4 years how airflow is affected and much oof the science behind flying a plane is involved in cars (i.e. venturi effect in a carb is what makes wings create lift).

If you really want to improve gas mileage, see if there are any underdrive pulleys available for your truck. These slow the accessories down, reducing parasitic drag. Do proper maintenance, use the recommended fluid specs, and drive at a reasonable speed. The faster you go, the parasitic drag is increased exponentially requiring exponentially more power/fuel to keep it going at that speed.

thats the point both vehicles did have intake systems in it and i am sorry i am not a michanic i am going by what me and my husband felt sorry.

Nothing to be sorry about. I just don't trust advertisements that sound too good to be true - they usually are. That's why I generally won't buy something unless there's statistical data backing up the claim. And for me, seat of the pants is not enough. I've fallen for it before. Do so and so to your car expecting more power and you think you feel more. Then you do a dyno and compare it to the old and realize you've gained nothing but a lighter wallet.

Turbulant airflow is not needed until after it goes through the throttle body. Any restriction before the throttle body will cause the airflow to be changed. Less air will actually go through the throttle body therefore making more fuel actually be used as the fuel is metered by the MAF. The more air goes in, more fuel is added to compensate for the air. More fuel, more power. More fuel, less mioleage(??) Just my opinion. Glad to have your input into the forum.

The Tornado Fuel Saver has been around for years now, claiming to give you an increase up to 24% in gas mileage.

The theory behind this device is that is will swirl the air coming in from the intake, which when mixed with gasoline will increase combustion and make the combustion more complete. In theory this means you have to use less gas to achieve the same speed and power, resulting in higher miles-per-gallon.
Many independant magazines and websites have tested this device over the years, which have all concluded that this device will not work, especially on modern fuel injected cars.
Even though Consumer Reports, the Department of Energy, the E.P.A, and countless other resources have tested this and other similar products with no positive results, people still convinced that this item may work.

Below is a review of the Tornado Fuel Saver from amazon.com (http://www.amazon.com/exec/obidos/redirect?link_code=ur2&camp=1789&tag=filamexperien-20&creative=9325&path=http://www.amazon.com/)

The Tornado Fuel Saver is a great idea for the patent holder and anyone else making money from its sales.
As an automotive technician I have encountered many devices that claim to improve performance or gas mileage. The Tornado is nice and shiny and makes an excellent paperweight or doorstop.

The theory of swirling the air/fuel mixture into the combustion chamber is nothing new; many modern vehicles are able to attain this with intake valves that open at slightly different times. There is very little doubt within the automotive industry that the better atomization of fuel within the combustion chamber yields better performance and as a result efficiency (mileage) for each unit of fuel and air that is taken into the motor.

However the Tornado Fuel Saver does not work for most modern cars and here is the reason: <br>
When the tornado is placed before a Mass AirFlow Sensor, otherwise known as a MAF, all that swirling air will be turbulent once again after passing through the sensor. Most MAFs have screens protecting the fragile wires (Hot Wire MAF) inside. If you have a Vane style MAF, then your airflow is even worse. No help from the Tornado before the MAF.

Stock intakes these days have a whole lot of ridges and baffles built into them, some are for strength so the intake piping doesn't collapse under vacuum, some are there to help quiet the roaring sound of the intake. If you place the Tornado after the MAF, but still within a stock intake, you are unlikely to see any improvement as the ridges and pockets will cause turbulence.

A modern vehicle with Sequential Fuel Injection will not see much benefit. Usually the fuel injectors are pointed towards the intake valve(s) meaning that fuel is squirted on top of the valve seat. This is where the swirling is the most important; however this is well into the intake manifold where a Tornado cannot be installed.

Fuel injectors on a modern day vehicle are designed to atomize the fuel as efficiently as possible. The atomization of fuel is in the design of the intake manifold, the fuel injectors, valves, and head.
The vehicles that it may have a positive effect on would be the older carbureted cars with an air filter that sits directly atop the carb. The swirling may help atomization a minute amount as the air passes through the carburetor's venturis. However, the benefits in that case are still minimal and not worth the lighter wallet.

Tornado Fuel Saver's infomercial mentions commercial vehicles while showing large 18-wheel big rigs. The mention of using one of these on a Diesel engine is laughable. Diesel engines compress the incoming air before fuel is added to it, once again the gains are minimal, assuming there are any gains using this product in a Diesel engine.

Some vehicles these days, especially European cars, are equipped with turbochargers (Kompressors for you Mercedes folk). A turbocharger unit forces more air (measured in Cubic Feet) and pressure to the engine. That extra pressure, commonly called "boost" helps atomize any fuel that has collected at the valves. (Fuel injectors running at a low 50% duty cycle are still spraying on a closed valve about half of the time). The "extra" air forced into the engine allows for more fuel to be burned during the combustion process. This creates an engine with a higher volumetric efficiency, meaning more power/liter for that particular engine. If you have a turbocharger, you don't need a Tornado, because you already have something much better.

The mileage gains that people see are likely to be from driving habits. This claim is backed up with anecdotal evidence, someone explains that their first tank of gas with the Tornado went a long way, but after a while it dropped back down. How can this happen? Its the right foot.

When gas prices jump, everyone is easy on the gas. Mileage is on your mind every time you pull away from a stoplight, the same happens when you install the Tornado. The first few days you are easy on the gas, improving your mileage, after a week or so you get back to your normal driving habits and your old gas mileage.

On John Matarese's &quot;Don't Waste Your Money&quot; website, he found the Tornado Fuel Saver to offer no more than 1% increase. Read about it here (http://www.wcpo.com/external/dwym/c3b519.html).

The bottom line is that if such a simple device really worked, it would come pre-installed on all vehicles from the manufacturer. If you insist on spending this money on your vehicle, you would be much better off getting new tires or perhaps buying a bicycle to use instead of your car.

RahX thanks for the informative article. It's the old self-fulfilling prophecy. You think you are going to get better mileage. You have a feather-foot on the gas and you get better mileage. btw the Tornado that sold for $70 you can now get for $16. Remember when it was the magnets on the fuel line that sold for $18. How bout the tablets you put in the fuel tank? From the 80's there was a device that allowed you to burn water by injecting it into the intake manifold. The list goes on and on. A fool and his money are soon parted. Any reference to a previous post is entirely coincidental.

The water mist in the intake works pretty well on supercharged/high compression engines to keep the combustion temp down and they actually make a tad more horsepower. If you want to spend the time setting it up right so you don't make a mess of the bottom end =)

Water misting actually did work like stated above. If shot in the proper amounts, it won't bend the piston rods. It cools the cylinder while expanding into vapor which increases compression in the cylinder = more horsepower. It was used on alot of WWII fighter planes to both cool the engines to effectively increase the octane rating of the fuel (decrease pinging) and add that extra power in combat.

Because of this, jet engines perform better and with more power on heavy rain days than on dry days.

But the Tornado thing, I think most of us agree there's no proven science behind it that is effective in a modern vehicle. Or any vehicle for that matter.

How about a urinal, or toilet!

yea but i am still going to do it my way and use the tornado.

Good for you magnum357. Stick by your guns.

sure will way thank u

sure will way thank u
He drank the Kool-Aide! :runaround: What the heck. he's doing his part to stimulate the economy! Let us know how that works out for ya. When you really want to increase your performanse & MPG at the same time, remove your SPOUT Connector Plug and advance you base timing 4 degrees. Put the plug back in & your done. You can even keep your turbulaterater thingy if you want. A shop will usually do it for $15-20. Takes less than 5 minutes. The next Mod is about $2oo. Ignition System upgrade that allows you to increase your plug gap to .054 from stock .044. My 87'302 gets 17/23 mpg. At 80mph, I still get 18-19 mpg w/ a 1200 pound payload.

For one thing i am a woman and second we are not throwing a way our money for us it does work and every vehicle we put it in so far it has given more power and race car drivers are using it too.

For one thing i am a woman and second we are not throwing a way our money for us it does work and every vehicle we put it in so far it has given more power and race car drivers are using it too. All Race car drivers are doing this! Long before the Turbulatorator was even a recycled Coke can. If it works , fine. I'm just offering you 2 more MPG's & increased performance that works on any engine. Free if you can time an engine. $20. if you pay to have someone do it! 10 BTDC is skock. you want 14 BTDC.

Me and my husband like what we are using right now which is the tornado.

Magnum, he's not saying don't use it. If you like it, great. We just feel the need for more of a "proven" method which includes both dyno and real world numbers.

What he is suggesting will save fuel and add performance, though. It's rather easy to do if you have a timing light. Just advance the timing of the spark a few degrees and you burn fuel more efficiently. I advanced my timing enough to make the best use of 93 octane fuel (87 is recommended for stock). The advance in timing gives me more performance since the fuel is igniting earlier and reaching the piston at just the right time on the power stroke to make the most efficient use of that energy. It's free to do if you read how to do it. If you have a car with Coil-On-Plugs (COPs), then it's even easier, but may require computer software to do it, like in my case.

i dont have to prove to u anything we find it works for us.

Nevermind, you seemed to have missed the point of my post. I wasn't trying to be offensive, just giving you and anyone else reading the forum an additional way to gain power/mileage.

ok what ever

OK Y'all. Lets not get in an uproar. Personally I do not think the things work. But if magnum357 believes they do, then they work for her. So please do not get violent in here. Please agree to disagree. Thanks and enjoy the forum. way2old

I am sorry but i am being nice

I am sorry but i am being nice
And w/ a screen name like "magnum357", it probably wasn't easy!

I am sorry but what does my screen name have to with it i just happen to know how to shoot that weapon.

He was joking that the .357 Magnum usually involves not-so-nice encounters. But they are nice revolvers. I've only had the opportunity to shoot one once a few years ago.

ok know problem:rofl:
