Does anyone has this $70 gadget on his/her Durango? Apparently it can save some fuel and it is just installed in the air intake before the throtle body without any bolt.

Mmmmm I don't know. Any opinions / experiences out there?

Regards,

 

Someone posted something about this before and to sum it up it is worthless.

 

I agree the tornado is worthless. Also before you ask don't waste your money on a throttle body spacer either. Dodge engines are not the right type for any of this junk to work.

 

Thanks for your opinion. I tried to search but nothing appears under "tornado" or "turbonator" at this Forum (2nd gen). A non-moving part playing with air before the throttle and the manifold doesn't make any sense. The "tornado" will disappear a soon as it gets into the intake manifold.

I will better try the K&N filter which better feature is durability an no system modifications.

i just did a simple k & n replacement drop in filter and saw approximately 1mpg gain in fuel economy. I purchased it from http://www.ajusa.com great price and quick delivery

 

Yeah the Tornado things are a load. Anything you put inside your intake track that takes up volume actually reduces the "free flow" of air and should actually reduce power. You actually want to aim at reducing turbulance (or spinning air) rather than creating it when your trying to get maximum air into the throttle body. They don't even try to hide the fact that it is BS in their commercial on tv. You can see them dyno testing an LT1 Impala SS with it. Notice the first dyno run ends at a lower rpm than the second one with the tornado installed...giving those amazing power gains that they claim. The best intake is a large, straight, internally smooth air intake tube that has as few bends as possible, protects the air coming in from the heat of the engine (cooler air is better), and having an oversized filter like a K&N cone mounted on the end of it that draws in ambient outside temperature air. Headers, a high flow cat, and a free flow catback may help too. I went from the factory 28mpg highway mileage to 32 mpg highway with intake\exhaust on my Grand Prix.

 

That was a great explanation! When I saw the additional boxes attached to the air hose I suspected that they were there to get fresh or coldest air into the TB instead of hot air. So, in resume, cold air and volume is the best thing for the TB.

true, cold air is more dense per unit of density. Therefore more O2 per unit of air with a lower temperature.

 

Well I do not have a 2nd generation D but I do have a 5.9L 1st generation and while at the junk yard helping my friend find a part for his Ram, I found a 2002 Durango there so I walked over to inspect the damage, while looking under the hood, I seen his air filter housing had been cracked open, I looked inside and seen a Tornado sitting there!! I was like a kid in a candy store! I pocketed that thing quick and couldn't wait to get home so I could install it. It was a little bent from the wreck but I straightened it out and slapped it in my K&N CAI and waited for results.....

and waited....

THIS THING IS A POS.

I am glad I wasnt one that actually paid for it, do not waste your time or money!!!!!!!!!!

 

Fuiuf! Case is now closed. Thanks everyone for your opinions! specially the last one who was able to live test one of these devices.

Drive carefully.

PS: I'm not looking for more power... just for gas economy.
