Anybody towing with the TAG device?

Turbo Air Guide, as offered by Diesel Power Products.

They claim a reduction in EGT's and a gain in MPG-- was wondering what your experience with it was??

 

Do you have a link......I don't understand what this device is

As you guys know -I am opionated and wrong at times mabe this time too........But I dont think so or they would be on all the racers allready.
Also they would be in the front of every fan jet .......I think some INDEPENDENT testing would be in order for this snake oil............

 

Doesn't everybody?

The way I see it, this thing has to reduce the overall size of the air opening just by being there. It may be small but it still takes up space. So it has to reduce the amount of air that can move through the opening, even if it is only a little.

I can't imagine the air turbulance is that significant to begin with considering the amount of vacuum these turbos can generate. Seems like one of those things where the benefits and the disadvantages would just cancel each other out.

 

Ok I looked at the link....looks like smoke and mirrors to me if its such a great item and reduces emissions the OEM's would be installing this item

"This test shows a 45% reduction of emissions using the TAG. Which helps to explain the reports of less smoke while towing and increased mileage under loaded conditions".

Wonder why they don't use dyno numbers to prove their point

"The stock trucks have gained a noticeable seat of the pants power increase just as the modified trucks".

NO MORE TURBO NOISE !!

"Turbo whine is way down, if you're the kind of guy who likes to remove the silencer ring forget it. Mpgs were about the same. Seems to spool up faster also"

Think I'll save myself $149.00 and not buy one of these

 

i'm with pappyman, if it won't move the numbers on the dyno, it won't move the buckfifty out of my wallet

 

I think you guys are very opinionated!!

But I think you are right!!

 

Straightening vanes are usually found on stationary water pumps and such that see constant flow and are at constant speed. The theory is that the fluid in the inlet tube begins to spin as it enters the pump impellor and causes in some cases caviation.

If the engine was set to run at 20 psi boost at 2100.01 rpm all day, then I think this device may work.. But on the open road the inlet air doesn't have time to develop this swirl effect.

I haven't seen it applied to anything in the industrial sector with respect to stationary generators etc. that are at a constant load and speed. So I too am a little leary.


There is another opinion...

J-eh

If you go down on this page, you will see test done.

Hmmm...
Seems everyone thinks it's all smoke and mirrors.

I think there are a lot of good products that OEM mfg's don't bother with, just to keep the overall price down.

I mean, look at the 3rd gens compared to the mid-2nd gens--no rear fender liners, no underhood insulation, etc,etc.

Guess I'll be the guinea pig for the group and try one of these out. I tow pretty heavy 19,000 GCW in the Rocky Mtns and have high EGT's pulling the longer passes.
Want to try something other than a $1000+ larger turbocharger.

 

You are 100% right. And I think TAG is worth to try. If this statement is right, it is not so expensive for the gain in power.

The dyno run above is a 2002 24 valve truck which has been modified with injectors, 100hp fueling box, 315 tires, 4" exhaust, 6-speed and aFe intake. The red lines are with the TAG and the blue lines are without. The vertical line at approximately 1,600rpm shows an 8hp and 27.7lb-ft increase using the Turbo Air Guide.

 

I'll note that K&N makes this same claim for their air filters -- they straighten out "turbulent" air. How seriously do we take that claim?

You might be able to get a very minor (read: hard to notice or quantify in the real world) benefit from designing an inlet that is straight, uses screened cell-columns to improve the laminar flow, and is baffled to cut down on backpressure pulses. I've read that the device would have to be at least fifteen feet long.

So I'd have to see the TAG dyno results in "real life".

To be fair, there are people on TDR who swear by the TAG. So try it out, and tell us what you think. I'll try to keep an open mind.

 

THERE IS only one thing to note here -in torqconverters and turbin eng. there are things called' stators' which staighten out the flow of things........they have direction built in them and are very hi tech.
So I am back where I was, PROVE it, there is nothing wrong with that request. Period.
same dyno.
Same eng........the only change will be the what ever you call it then I'll shut up.
