Default Tornado fuel saver

Has anyone used this?

I ordered one but have yet to get it delivered. It will be interesting to see if I see any fuel savings or HP gains. It does have a $ back policy if not.

I had one a while back. It's sitting in a parts bin now because I have a different intake. I'm not sure if it did anything or not.

Question

How can it possibly help a fuel injected engine.....?????

More air in......the vortex thingy has no validity aft of the throttle body??? How do they possibly get away with selling this GARBAGE?

OK......you buy one and share your results

The thing I love is that they claim it helps turbocharged engines, when installed before the turbo

The tornado is crap. If you ever see on in person you will see why.
You know what would reall help, a bell shaped opening on top of the carb (the only cars the tornado "could" work on).

Do you realize how much research goes into the intake design? Why do you think the intake has a tube sticking out the side on newer subaru engines and how the snorkel has such a whild design.


BTW, I keep every single gas receipt I can for my cars. Right now center console on my legacy has a ton of them, each with the milage written on the back.

I did this with my supra, while it was NA the tornado made no difference in fuel economy. Actually after installing it my fuel economy was a little worse, but it was such a small difference I didnt count it.

Dont fool yourself, oh and dont you find it weird that they have a link to bible messages as the FIRST link on the menu bar?

Just save yourself the time and effort and send it back as soon as it gets to you. The Tornado is nothing but snake oil.

Why does the intake have that tube? I've always wondered.

I'd venture to say that the bizarro snorkel is all about packaging and silencing capability, and nothing to do with good airflow. And what the hell is with the "torque box" or whatever you want to call it? That thing is pretty asinine.

I'm hardly a proponent of the Tornado- those things are absolute garbage. But I'll argue that the stock Subaru intake is a bastard child of noise reduction + placement + uneccesary fears of water ingestion + wacky throttle body design + a bunch of other useless crap. It appears to be an airflow nightmare...

HIHO, most infomercials are like that. That darn sleep thing cuts into my infomercial time though!

Sidenote: I'll save my money for something more substantial like new tires or something.

This man is a genius. How many millions to GM, and Ford put into making their full-size SUVs earn one more MPG so they dont have to sell as many fuel efficient cars, and therfore keep their CAFE (Corporate Average Fuel Efficiancy) numbers ? And all this time, all they have to do was spend Seventy bucks (+ ten on shipping) to get a twenty percent increase in Fuel Economy AND 4-13 more horsepower ?

No wonder OPEC has been so nervous lately and has done nothing but drop fuel prices all year ! No wonder George Bush has been working so hard to keep oil companies from messing up Alaska with all their refineries !

Tornado Fuek Saver <---- Click that, OPEC !!!

Seriously let us know how well your car does after 2-3,000 miles with this special Swirl induction... Be sure to keep close tabs on your fuel milage.

Well with two days of use I have no hard numbers on HP or Fuel savings. The thing I did notice right off is there is no hesitation or jerking in 1st gear. The car use to lug really bad in slow city traffic. I had to keep my foot on the clutch and the give it gas at the same time. If I didn't the car would just jerk and lug forward. Now it is as smooth as the wifes MR-2 Spyder.

I'll take it out today to make sure it just wasn't a loose vacume hose.

Power does seem to come on a more effortlessly now. Maybe it just seems that way since it runs smoother in 1st.

Default Has anyone every broke the 400 mile mark on a full tank of regular gas with mixed Hig

Results are in..... You tell me if you think the Tornado makes a difference.

After two weeks of testing and a long trip here is what I have noticed. Keep in mind I have new tires and the oil is due to be changed (2 weeks ago). I currently am running Moble 1 Synthetic and always use regular unleaded gas. My 2.5 has 83,000 miles on her.

I have managed to get 375+ miles out of a full tank of gas. This was city and freeway driving. Half the trip with the A/C on. While on the freeway I set the cruise set at 73 mph.

When I did fill up, the gas light was on (The needle sits way below the E before you will see the light). It seems funny that the car only took 13.5 gallons to fill though. This means I still had 2.5 gallons left! That would have taken me a minimum of 50 more miles. Has anyone every broke the 400 mile mark on a full tank of regular gas with mixed Highway/City driving while using the A/C?

As for the HP increase..... I have no clue. The car does seem to pick up much quicker on the freeway in all gears including 5th. It also seems to run much smoother. Especially when pulling away from a stop light or when in low gears in heavy traffic.

Does the thing work. It seems like it. You tell me?

I did 400+ Miles driving up to see the Maine Forrest Rally last year (2001), although that was largely highway & empty seconday roads... So far your results are very impressive.
let us know how it stands up over say 2,000 miles ?

Yeah there is a sucker born every minute... If you keep posting such positve results, I guess I am likely to take the bait as well.

Thumbs down

Nope...not buying it! Cannot work on a fuel injected engine....

If you want to believe then believe.......but you will have to ignor all technical/engieering principles and any basic understanding of how a fuel injected gasoline engine works.
More air is good (CAI).......tornado= rip off

lakepop, you said it yourself..... "More air is good". That is exactly what the thing does. Forces more are through the intake.

I'm not the most technical person in the world but I do have better miles per tank then before plus the car runs much smoother.

On my next long trip I will take it out to see if I have any negative results.

I'll let you all know what I find.

Default huh?

Now wait a sec....There is no way this thing "forces" more air anywhere. It does not move. Infact, I think they advertise the reliability due to no moving parts So, even if the "tornado" effect takes place, there is no way that it forces air into the engine. If anything, the tornado restricts airflow because it is an obstacle for the air to pass by. How about this...if the Tornado "forces" air into the engine without moving, how about mounting several to the roof and sides of your car. Following their theory, the Tornado's should "force" air through themselves, causing the car to haul ass down the road. Someone try this and let me know if it works...if so, I'll take two for my foglight holes

THE TORNADO DOES NOT WORK!!!

Learn some more about cars before you buy into the lies. You will save yourself alot of money.

BLZ2DWL: Hey I know, you could attach a bunch of them to the side of the car and have the angle adjustable. If you need more overstear just point the rear ones upwards and the front ones down

On a side note, someone verify this for me. Im fairly sure that the injector is activated once before the intake valve is opened in order to

Cool the valve
Atomize more fuel



Anyways in order for the tornado to make any kind of difference the "swirls" it creates would have to travel through the throttle plate, down the runners and past the injectors. There is so much turbulance on this route there is no way any swirl effect would be left. ESPECIALLY PASSING A PARTIALLY CLOSED THROTTLE PLATE. How much throttle are you using when at cruise? maybe 15-20% at most? The throttle plate has two different pressure areas around it. The lower portion becomes higher pressure and the upper portion becomes lower pressure. Just this alone would destroy any swirl that took place over the entire intake piping.

It would be cool if somone made an intake out of clear plastic and ran smoke through it, sort of an internal aerodynamic demonstration. Then we could really see the effects.

It claims to help the air fuel mixture. There is no possible way that a angled metal circle can do that.

I believe that it swirls the air coming through the intake. To get the best air flow you want to get rid of ANYTHING that makes sudden changes in the way the air flows. That is why people get rid of the factory intake and replace it with a smooth strait tube.

Well guys if the Tornado does not work (your opionion and I assume lack of testing) how do you explain the fact my car no longer jerks in low rpms in a high gear? Also why has my freeway milage increased to almost 400 miles per tank before the fuel light comes on?

Did you get these new tires at the same time you installed the "Tornado" crap?

If so, there's your answer. If not, your mileage increase is due to something else.... Did you put on a new air filter? Switch gas stations? Jiggle a vacuum hose? Pull a dead bird out of the airbox? Rolled up your windows on the highway? Stopped driving with the pedal crushing the carpet all day,

Whatever the reason, it isn't the Tornado.

Actually, this same thread occured on a 4runner board that I used to frequent, before I got my subie.

Same responses - everyone telling you why it doesn't work, and one person actually using it, and reporting a mileage gain. I'm not saying that it works, but all first hand experience I've seen reports a small mileage gain in conjunction with installation. Certainly, this could be corollary, not causal.

At a basic level, though, anything that alters the airflow pattern has the ability to alter performance, for either good, or bad. It is a fact that a vortex will create a vacuum, at the source end. Whether the increased air volume created by the suction of this vacuum is greater than the constriction caused by the tornado thing, I don't know.

jacksonww: Perhaps you didnt read my post. I tried the tornado in my supra and there were no differences. My fuel economy had decreased slightly compared to previous but the change was small enough that I just had to count it as a sampling error.

Here is how you can prove it. Fill the car up until the fuel is outside of the little trap door, wait a second as sometimes it bubbles down.

Now go drive somewhere, say 50 miles and back to the station. Fill the car the same way and you have the amount of fuel used on the first trip. You can write down the miles and the exact fuel used down to 1/1000 of a gallon. Take the same route with the tornado removed and return to the gas station. Fill up the same way (just above the door) and you will be able to tell pretty acuratly how much fuel was used.

This is EXACTLY what I did. Except my trip was about 80 miles total.
