has anybody used so called "Tornado Fuel Saver?" Does it really works as it said? or is it just another scam...

They don't tell you how it works on that site so it's hard to know. Looks like it is suposed to increase air intake which you can do by installing a $30 cone air filter and $10 adapter rather than $70. Looks like a waste to me but I can't say for sure.

Save your money.

OR you could send me the money and I'll send you valuable information on a dangerous chemical called dihydrogen monoxide or DHMO for short

pssst.. by the way

WATRD

Send me the $80 that you would spend on it, $69.97 + $10.95 shipping and handling. I will then kick you in the shins and you will have received more for your money than you will get from sending them the money

Worthless.

ooh ooh, do you take paypal?

I watched an infomercial on it...

...the fins are supposed to make the air that comes in spin and create a "tornado" affect and thats supposed to increase hp and mpg.....

Tacoma Dude

Not scientific by any means but try looking at these reviews:

That is the same theory behind a thotle body spacer isn't it? Thoes are suposed to cause the air to roate and increas hp and from what I have heard, those catually work. There might be something to this devce but I'm pritty sure you could do a lot better with an air box mod or something which is free of cost.

I researched the Tornado fuel saver this week. It looks like it is a scam. Check out these sites:

This quote kinda says it all:

rimpainter.com

The spacer doesn't do crap - on Toyota's anyway. Can someone explain to me how one vortex of air can get itself into six different runners?

I have owned the Tornado. Didn't do squat.

I have owned the TB spacer. Didn't do squat either.

Don't make the same mistakes I did.

(The Tornado was on my 79 Supra)

I did have a friend that managed to suck his tornado into the Throttle Body of his VR6 Jetta, causing it to stick open at WOT. That was interesting.

I had the tornado in my 4runner when I got it. First mod was to remove it. If anyone is still foolish enough, i'll be happy to sell it to you for 15 bucks shipped, but I promise they're worthless.

SoCal4Running

If any designs like the tornado or the fuel magnet ect worked period the auto-manufactures could and would add them to increase economy for mear pennies.

ChickenLover

If I recieved one for free, it would be tossed into my pile-o-things for the 12 guage.

PirateFins

Always have a thirst for knowledge, I must check out that chemical. Anyone have the MSD on it, you know, in case I swallow some?

Yes its a scam, and yes it does work. Lots of folks here have one and don't even know it.

It works in lawnmower engines. Briggs&Stratton has had a coil in some of their intakes for years now, decades in fact. A long intake runner coming from a sloppy carburetor has problems with fuel dropout. In this specific case, having a tumbling intake keeps the gasoline droplets suspended so the engine can run.

In a car, particularly a fuel injected one, it's a total waste and a scam.

Their gimic display of the two soda bottles joined by a little tornado device is a trick. The reason it "works" there is because by swirling the water onto the sides, an opening is made in the center for the air to rush up from the bottom as the water flows down into it. No special "flow" increase for the water at all, just a faster escape for the air. Vent the bottle and it does just the same. Don't swirl the water in the vented bottle, and it will flow down even faster. You can do the swirl thing without the tornadeo by just swishing two bottles joined with a piece of duct tape.

X-AWDriver

People on this board have $70 TRD shift knobs in their trucks and they add about the same horsepower as a Tornado.

The Tornado may cause a swirl in the air stream but as soon as it hits anything (curve in the pipe, throttlebody inlet...) that stream is interrupted/broken up and no long effective....its a waste of money and you are just adding another restriction in your airflow.

Headers increase fuel economy and power. Larger exhuasts increase power and fuel economy. A supercharger marginally increased my fuel economy and dramatically increased power. DOHC engines are far more efficient than SOHC engines. A K&N or Amsoil air filter increases air flow and filters better. Ceramic piston rings create less friction than conventional rings. Why don't auto manufacturers install all of these on every car?

rimpainter.com

I will give these a shot…

I think this comes down to cost and reliability. It also has to do with where they make more power (a higher RPM). Most people need low-end torque for daily driving. Cast Iron is cheaper to produce and it dissipates heat and reduces under-hood temperatures better than a standard header without a coating.


Generally speaking larger exhaust is louder and the cost is higher. Again, people want low-end torque for daily driving.


True if you mean power, but for gas mileage the SOHC Honda Civic HX takes the cake.


I think it all comes down to one word: Cost. Not only are the tool set ups more expensive for these parts, but labor is more intensive and general procurement would cost much more. If you start adding these things up, the cost would be notably higher in a lean production operation.

Besides, we wouldn’t get to mod anything if they all came this way.
