Tornado Fuel Saver

Toranado fuel saver

I got one of these for the wifes 2002 Dodge Durango... 5. 9...

Did not run one bit better nor did it get any increase in mileage.

It still passed everything on the road except "gas stations". .



Traded that in on a 2004 VW Touareg... !!!!! This is a NICE car !!

TAG

Anyone interested, I dynoed w/ and without TAG. Major difference - No, Difference - Yes. Turbo spooled 200 rpm quicker which I like a lot. Under heavy load - no more hp, but no less either (for those who suspect reduced air flow).

Did a fairly extensive controlled road test. Noticed one major difference. With a TAG it takes less Boost to hold a chosen speed than without TAG. Not a lot less-but less. This fact translates to more efficient engine operation, IMHO. Suspect difference would be greater if towing.

Tag also reduces turbo whine. Some don't like this-I do.

Anyone with Excel who wants to see the results - PM my your e-mail address (don't know how to attach data to a PM).

Towing is where we have seen the best gains from using the TAG and everybody likes the quicker spool up. Thanks for posting your results. We are cutrrently testing a second version of the TAG for the 2003-2004 Cummins which moves the TAG about 1/4" farther away from the turbo. Moving this little distance increases turbo sound noticeably with performance virually the same or just slightly better than the current TAG.

I think P. T. Barnim said it best. There's a sucker born every second.

Congratulation Mad Bomber

Not only did you manage to mis-spell and mis quote... . You managed to put a negative comment and a cliche all in one tiny sentence.

Your obviously not interested in a TAG. That's your right. I bgt. one to see if it worked for me - it does. Why don't you save your money for the leather and save the mud slinging for another web site!

This piece, along with the secret 200 MPG carburetor, are what makes crooks money. If you think about how it is supposed to work and how an intake system is designed, you will answer your own question. save your money.

Hohn,



I understand what you're saying. I did say that I believe that the TAG is based on sound engineering principle. Regardless, I stand by my comment. If there was a SERIOUS design flaw in the turbo inlet pipe it wouldn't have been built that way. As you say, OEM's are always weighing the cost. Wouldn't cost Cummins much to have a different shaped turbo pipe, or to install a factory TAG, for that matter. To be clear: I believe (based on my experience) that the TAG concept is sound engineering principle, but I don't believe that you will see 4 mpg or an extra 25 hp using it!

Cummins has spent some serious dollars redesigning our engines lately in 2003 and 2004. 5. If a big advantage would be gained from a redesign of the turbo pipe, I have some faith that they would have done it.

Anyway, my original response was to the "Tornado Fuel Saver" and nothing has changed my mind in that regard.



As I said before, if I experience some of the full load/full boost turbo noises that others have reported, I'll order a TAG right away. But I won't expect to notice a significant change in fuel economy or performance.



Cheers

The thing I see here is the fact that we have one engeneering department (Cummins), putting their product in anothers engeneered product (Diamler Chrysler). It is probably not how Cummins would have engeneered the intake. But, somehow they have to squeeze everything under that hood, without lengthening the vehicle to accomodate a straight air duct. Thus aft engeneering comes into play (Diesel Dynamics).

Also I believe what Hohn said about bean counters has definate merit. Just my $0. 02

What are you referring to in this post?

Are you talking about the TAG 111, or are you working on a newer model than the TAG111?

200 mpg carbs probably do work!!

This piece, along with the secret 200 MPG carburetor, are what makes crooks money. If you think about how it is supposed to work and how an intake system is designed, you will answer your own question. save your money.

However, they are so dangerous that it could not be trusted in the hands of the general public. I vaguely remember reading the 200 mpg material. And if I remember correctly, I think they were telling how to do it, not necessarily trying to sell you anything. Also, I think that the big oil corporations may have something to do with squelching the technology. I am sure that I could be wrong on this subject, as I was wrong once before :-laf :-laf

I have found this to be fun reading, if nothing else.

 

[Car_nut57]

I say to you, Cummins seems to be pretty much up on things. If the TAG was so dang good, why isn't it installed at the Cummins factory? Or better yet, Let me know if you see one in the new 600.

If you remove the intake hose from a 600, you will find air directioning vanes in the elbow just in front of the turbo. Its not enough to condition the air like a TAG does, but Dodge must have felt it was worth doing.

 

[Car_nut57]

Are you talking about the TAG 111, or are you working on a newer model than the TAG111?

Yes, its the TAG-III which is currently available although a little different than what we were experimenting with in Feb. 2004.

 

[DieselDoghouse]

OK here's my worthless 2¢…Physics class was a long time ago BUT. A device that 'aids' charge air entering the engine I think would be worthless—like Tim said—its charge air. A device that aids the turbo in collecting air, where the system isn't charge but a voracious induction system (TAG?)—that should work! That's cause the 'pump' (turbo) pushes better than it pulls.

 

[ARARAR]

?'s about the Tag.

Straightening ou the air sounds ok' but swirling the air in the opposite direction of the turbo wheel seems to make more sense to me. But what do I know?

TAG and Tornado

I installed a Tornado 3 or 4 months ago. I did the install along with several other things so I can't say what good it did. Yesterday I had a little spare time so I removed my intake air tube from the stock air filter to the turbo. I have a 2004. 5 ... After hearing a few guys talking about removing the silencer ring and baffle. All of this tube being aircraft quality space age plastic... I was very careful in taking the tube apart. It took a hammer and flat blade screw driver. After removing the plastic ring I took apart the inner tube and removed the baffle. All the hipe about smooth air flow it is no wonder the stock baffle and tube might be a problem. The inside of the inner tube has 6 or 8 large rings around the inside. It is no wonder the air flow is disrupted. After removing all this baffle I put the ring back on the air tube and used PVC cement to glue it back together. I hear a slight turbo spinup and it seems to breath much better. This TAG folks are speaking about straightning out air flow. ?? The space age rubber 90 degree elbow that is connected to the turbo has a 2 bladed plastic fin that helps turn the air around the elbow. How does the TAG help air make this turn?

Tornado...?

The "Tornado" concept has been around for decades. I remember a similar device being touted just after WWII. It had a propeller that "swirled" the fuel/air mixture (as if the throttle body and manifold weren't enough) to provide a better mixture of the two. Another that came later was of an almost identical design of Tornado's and while I believe that Whitney sold them for quite awhile, I hadn't seen them since... . until this latest manifestation appeared on the scene. The part that p*****s me off :-{} is the fact that the "Two Guys Garage" show touts this product as it does a lot of other questionable stuff as being used by them and tested for quality..... ?? Caveat emptor!!!

 

[Warpig]

TTT you paint these pictures of doom and gloom, trucks burning to the ground, turbo's exploding with fierce fury. My gosh do you walk around looking for airplanes that are going to crash into yourself? You were probably exaggerating to prove a point, but i know someone who acts like that and it's a rather strange feeling to be around.



LMAO..... :-laf You ain't seen nothing yet.

Tornado

I'm keeping my Tornado.

 

[rbattelle]

Just saw Sam Memollo (sp?) in a commercial endorsing the Tornado.

tornado dyno results

Tested one once on a chasis dyno. our car was a stock z28 camaro 98 i think, it had a manual, and a k&n filter thats it its been a few years so i don't remember exact numbers but i know no horsepower was gained and we lost around 5 ft lbs of torque. tried it a couple of runs and same result. cant tell you anything about fuel milage though, thats a whole different test.
