gets the dust to go to the outside of the casing and fall out before it hits the filters.. that is what ours do in the heavy equipment we have.. that is my guess

 

Hmmm, I'd say his truck is reacting positively to the cut up soda can. He's got numbers in miles and gallons to support that HIS project works on HIS truck. He's not saying it will work on everyone's truck every time. We've all read the popular mechanics testing that it is a scam but maybe his truck is one of the exceptions. Lets not forget Popular Mechanics has promised invisible jets and hotels on the moon for over a decade(I'd pull the issues if I still had them).

On a dyno you test horsepower across the entire rpm range. With a driver focusing on fuel economy you wont be going there so maybe at low rpm/load the intake blockage is not as significant of a factor. I know for my truck the gotts mod did not start having an effect until about 2500 rpm at WOT but did have a peak efficiency increase starting at about 30 g/s (only seen at low rpm and low engine load).
...so I would not expect the tornado to be beneficial during a WOT run because it blocks air from being pulled in. That may be why you dont see them in production vehicles. You gain a small amount of fuel efficiency but take a larger hit on performance, especially with larger engines who's air requirements are much greater. You also introduce another object that could possibly break and get swallowed by the engine. No company is going to want to fill a million engine warranties just because of a slight increase in fuel efficiency.

 

A couple of tanks isn't enough. At best its causing a false MAF reading and he's running too lean, not yet enough to throw a code. Data logging the fuel trims and a wide-band will verify it. Also, don't forget that people often change their driving habits ever so slightly, often its not conscious, when making mods. For instance, you'll often see a significant mileage drop after adding a tuner because you get more aggressive on the go pedal for the first month or so.

As to manufactures not putting it in because of warranty concerns - not so. They wouldn't have it built like that, it would be part of the intake tract plastic so there's no possibility of it breaking off. The manufacturer's aren't using them, the EPA says they don't work, dyno results show they lose power, logic about how engines work says they won't work, etc.... there's not an ounce of credibility that this case is any different than people's butt dyno's saying a bs electric turbo works. The only way to increase power via the intake is to increase thermodynamic efficiency. Two ways to accomplish that: reduce friction (the Tornado does the opposite) and reduce temperatures for a denser air charger.

 

That's a very good observation. The fact that it's mounted toward the motor had me thinking though. Knocking the dust down and keeping it from swirling and blocking airflow is probably right.

Not enough for you. I dont think he really cares what everyone else thinks because it is working for him. Why dont you send him the equipment to monitor the fuel trims and wideband O2. If he is willing to try a cut up soda can I'm sure he'd be willing to try that stuff.

People at every respectable audio shop (and a few at Best Buy) told me I couldn't use the headphone signal straight from an MP3 player to power the RCA inputs on my speaker and subwoofer amps...well they told me that AFTER I had it work. Popular opinion can be wrong in some cases.

 

very nice i'm lucky if i get 10mpg

 

First off i never told anyone to buy this, i thought it was kinda cool that i got better mpg's with it then without it so thats why i posted this thread, just because it didnt work on your bro's truck doesnt mean that it wont work on someone elses vehicle.

Guess my truck is the exception , Now remember 2 of the 3 calculations was all flat highway cruising for 200 straight miles. Ive had the truck 2 years and put some 37,000 miles on it and it usually avg 17.5 mpg mixed driving and 18.5 highway driving. Put this tornado on and its went up the last three trips. Now im sure if i lived somewhere with alot of stop and go traffic the tornado wouldnt do squat. The worst mpg ive seen with the truck was 15 mpg and that was pulling a trailer down the highway.

 

Lucky S.O.B.

 

I'm not here to lend out expensive equipment to people I don't know. I have the equipment, tuning software (several), years of doing this stuff... why should I lend out equipment I use for things that work to a stranger to use to monitor something which doesn't? If the guy has a SCT or Diablo tuner he should be able to monitor at least the fuel trims.

Ignorance and the desire for something to work can be strong in many cases. Hence the number of these placebos sold.

 

Now that we have established the merits of the Tornado,
I would like to present for your consideration...The Turbonator!

This is like adding a turbo to your engine for only $69.95
No moving parts with gains of 12 to 65 hp, depending on who you are.
Money back guarantee (minus shipping and handling and misc)

 

Memory failing you, old man?

18-20 mpg. Holy cow I get 11.25 if I drive like a grandma

 

I forgot about this thread, but what was the update..

 

Update "When testing, if the results differ from the theory, BELIEVE the results and invent a new theory".

 

I wanted to try one, the guy at autozone said they have a bad habit of coming apart and getting sucked down the intake.
