Anyone out there ever try these gas saving devices that you put in the air intake..."tornado" or something to that effect. Any success? With the price if gas these days I would even consider voodoo if someone said it would work. | ||

Its voodoo - do a search | ||

how many woodoos does it take you to accept the present gas mileage? | ||

more like doodoo. Remove your maf screen for a better effect. | ||

You know what P.T. Barnum said "a sucker is born every minute". I wish I would have invented that thing. I could a have an infomercial at 2:00am selling those things along with quarts of the mystery oil with the "special lubricants" that coat the inside of your engine. But wait that's not all I'll thown in some of those deer whistles too. LMAO | ||

I suppose it's possible. It seems simple in design, but so are most modern conveniences. Perhaps this guy was just the first to market it. Benefit of the doubt, i guess... Even if it did work and saved a couple pennies a tank, how many tanks of gas would you have to go through to cover the cost of the device, let alone save money? | ||

The previous owner of my 96 RR put one in. I pulled it out, it was very cheaply made and looked like it cost about a buck or less to manufacture. Looked like pieces of tin tacked together, I was afraid that it might break apart and get sucked into the intake. Didn't see any difference in performance. | ||

Throw in a "Pocket Fisherman" and a set of Ginsu Knives and it's a deal. Well, think about the path the air has to travel to get to the combustion chamber - between the MAF and the spark plug, you go thru the plenum, which is larger in volume than the plastic duct the MAF and 'Tornado" fit in. At that point, the velocity slows down, so any whirling action disappears in the plenum. Then the air goes into eight different air horn, thru the intake manifold airways, into the intake side of the head, where the fuel is squirted in, thru the valve seat and finally into the chamber. A single "tornado" inserted that far forward of the spark plug is as good as a deer whistle. IF, you got eight "tornadoes' and somehoe put them in each of the intake manifold airways, it might do something. Be a test mule and report back. Awww, come on. | ||

what about just installing a mini electric fan into the intake. kinda like a mini supercharger? this would work better then a tornado in my opinion. | ||

I have actually tested this POS on my truck. The good news is that it really doesn't do any harm. I had a Tornado installed on my '96 D1 for one year. I keep fairly meticulous gas/milage records. There was absolutly no change of any significance in my milage between the year before I had it installed, or the year after I had removed it. During those three years my driving was consistent, including the same number of cross-country trips to the same destinations. If you think your truck will do better, I will be willing to try and find it. You can have it for shipping, and a contribution to Dweb. (E-mail me for specifics) My next test project, is to test one of those magnet thingy's for a like amount of time. -Reed | ||

Reed, you are a glutton for punishment, and I appreciate it. Report back on your magnet adventure, It also looks too good to be true. My only test project so far is the K & N Airfilter. I am resonably sure I have no advantage except the fly sticker in my window, and a thinner wallet. I also feel I will switch to paper again if I get into real dusty conditions. | ||

We tested a tornado in a new blazer in our emission lab at school. Results showed no gain, or loss, and this is using certified emission measuring equipment. | ||
| Jan Smith (Smithj) New Member Username: Smithj Post Number: 5 Registered: 03-2004 |
Also just a little side note on K & N airfilter. A new NAPA gold filter will out flow a K&N on a flow bench. Most other quility paper filters will flow about the same. As soon as a paper filter is used in the dust it losses the advantage. So in the long run a K&N is cheaper just by the fact it can be cleaned and reused. But if your going racing put in a new paper filter  We ran these tests on new style square filters for a Chevy but don't think it would change much for similar size rover filter. | ||

I was enjoying the comedy of this thread and the suggestion to stick an electric fan on the intake reminded me of a DIY Forced Air Intake story/hoax from a BMW site. Just think how efficient it could be made with a tornado too! http://www.bimmers.com/m3/hoax/ | ||

Reed - Be careful, if you use the Tornado in combination with the magnet your engine will actually create fuel when it is run, causing the gas tank to overflow! | ||
| Reed Cotton (Reedcotton) Senior Member Username: Reedcotton Post Number: 322 Registered: 01-2003 |
Rick- I am also extremely lazy. that is why I was able to test it for a whole year. The Paper vs K&N saga goes on, with hard core advocates on either side. If you are really getting into dusty conditions, get a snorkle first, so the air that the engine picks up is cleaner to start with. (If you don't believe this, after a dusty run compare the outside of the truck with the inside of the engine bay. It has been my experience that the dust is thicker in the engine compartment.) If ti is still really dusty, then use a prefilter at the snorkle intake. then go back to figuring out if K&N is better than paper. Ken- I actually saw something like that on e-Bay. For anyone wanting to try this, you might look at some of the beefier computer cooling fans.   - How about a cyrogenic plate in the intake to precool the air? Now nobody's Engle will be safe! (For you cheap guys, use a CPU cooler.) Pugsly- With high octane approaching $2.50/ Gal. around here, I can only dream about such miraculous solutions. But, I like the thought of having an "overflow" hoise sticking out of the open gascap and running up to an open jerry can rapidly filling on thew roof rack. (Kids! Please don't try this at home! The people on this board are professional humourists, and are fully aware of the dangers of laughing too hard.) | ||

Well to start with in order to get power you need to combine intake with exhaust. Overwise there is no place for all that air to escape afterward so it has to be two fans - one in intake and another one in exhaust | ||
| Reed Cotton (Reedcotton) Senior Member Username: Reedcotton Post Number: 323 Registered: 01-2003 |
Sergei- Youv'e almost got the right idea with the two fans. However what you need to do is to use the fan in the exhaust as a generator and use the power from that to power the fan in the intake. How's that for a really CHEAP (anyway you look at it) turbocharger.  Now put a kit togeather and sell it on TV and e-Bay you'll be rich beyond avarice. | ||

Reed...I agree with the snorkle (higher the air intake the better) with one exception...the engine bay is subjected to many types of sticky films (water, oil, grease, etc) which is most likely the cause of it "collecting" more dust. I don't think it would matter much if the air intake was inside or outside the engine compartment. But if it was higher, well that changes everything (except of course if you are in an Arabian dust/sand storm...then I hope you packed a spare paper filter or have time to wash the K&N). SandMan | ||

My disco is parked, and my motorcycle is getting all the use now! 45 miles per gallon is pretty darned good! And it has much better pickup than the disco! | ||
| Reed Cotton (Reedcotton) Senior Member Username: Reedcotton Post Number: 324 Registered: 01-2003 |
Ed- The only point I disagree on is that about if the intake was the intake being inside or outside not making a difference. In the engine compartment you have two front driving wheels kicking up a lot of dust, plus a very active fan to keep it in suspension. If you normally keep your engine bay clean the dust layer should only be a sticky film thick. It is my experience that the dust in there gets alot thicker than that. Of course dust stuck to the engine via oily film is no longer in play for the intake to worry about. If you are in real dust like described above, and have the infamouse K&N (like I do) you actually might be better off re-oiling the filter without washing it. This is good for about two times before it gets really choked, and the effect may be better filtration in the short time. Then was it when you are in camp and the dust isn't blowing. (Again most of the dust in the engine compartment is caused be two front wheels, and unless your life depends on it you shouldn't really be driving in the low visibility of a full blown dust/sand storm. In those conditions you will really want that prefilter even with a snorkle. (If you need to drive in it. Otherwise shut off the engine, and seal the intake for the duration of the storm.) James- My very next project is getting my bike ready to help me commute. On mine I would need 4 little Tornados to not do any good. | ||
