TAG ?? Anybody know about this ??

[Mundgyver]

Does anybody on the forum know anything about this system or have any experience with it??



The dyno chart looks interestingOo.

Check out this thread . It sounds very interesting.

SCAM!

I don't know about you guys, but it looks like total BS to me.



Reminds me of the EBAY scam a while back. . some dude was claiming to have an "electric turbocharger" and was aiming at the ricers. It was actually a plastic housing with a DC electric motor and fan inside, used for ventilating boat engine compartments!



That honeycomb contraption looks like a major diffuser, and a possible FOD (Foreign Object Damage) item for the compressor!



If you bought one of those stickers for your cellphone claiming to act like an extra antenna and believed it worked, then go ahead and buy one of these too. You deserve it! (Humor)

Um Chris, you have to stop beating around the bush. This having to read between the words with your opinion is getting tough

 

[KEarnest]

The idea behind the TAG is to increase the efficiency of the compressor by reducing the turbulence of the intake air entering the compressor. This equates to faster spool-up which = less smoke.



Here are a couple of installation photos I made the other day after installing the new TAG into my PDR HX40/16. So far, I have noticed faster spool-up (seat of the pants meter AND boost gauge), less smoke and quieter turbo whine (and I have a PDR40 that was machined for a silencer ring). Any of the noise-conscious CTD owners out there will love the TAG if for no other reason than it greatly reduces the turbo whine even with a silencer ring in place.



I haven't driven enough with the TAG to provide any fuel mileage data. BTW, the honeycomb material of the TAG is very strong and it is highly unlikely that it would find its way into the compressor wheel. Dave Meheen (inventor of the TAG) gave this matter considerable thought as he went through several iterations of design changes during the development of the TAG.



I went to a dynojet dyno center the other day so I could compare before/after dyno graphs of the TAG but my truck was too long for the dyno lift (they had an above-ground dyno). Hopefully, I will be able to dyno soon elsewhere and post results.

We are in the early stages of testing with the new TAG for the Cummins and very much in the collecting data stage of this concept. Most of the test trucks are 2003 with little or no modifications and couple of 98. 5-2002 trucks. Even though we do not yet have the dyno information available yet all the testers have reported quicker turbo spool-up, less smoke while pulling and turbo noise reduction. We have also been told of some mileage increases which I will not quote at this time.



Since the TAG is still in the testing stages we make no claims of any kind regarding its performance, but will report what our testers tell us and post dyno information when it becomes available. Testing is going well and we do expect to introduce the TAG for general use in the Cummins in November provided all goes well.

Car_nut57,





What would I have to do to become a tester for you. I do not live too far away and I have very detailed base line readings for fuel usage both loaded and unloaded for 99,233 miles with my 2001 H. O. Six Speed. My background is 18 1/2 years of of 21 in Marine Aviation as a wrench turner and 8 years working hi-vacuum manufacturing issue with molecular turbo vacuum pumps. I have a sinful knowledge of laminar air flow issues.

My intent is not to get a free one but rather to help out with my experience and buy a certified tested and quality machined product in the future.

WOW only 120$ for straight air . How about a straight air intake hose with out the bumps? If it sounds to good to be true... ... ... . Ron in Metro Louisville KY

I saw something very similar on a turbo car that was racing at our race track once. The car was a Supra with a massive turbo that ran in the 10's. Pretty neat car.

One TAG type discussion I read was the length of the tube needed to be 5. 5 times the diameter of the tube. The honeycomb seems fairly small diameter of each tube. Is the thickness of the TAG about 5. 5 times the diameter of each honeycomb structure?

Actually our cell length is 7 times the basic cell diameter to achieve laminar flow.

I've had a TAG on my '03 for about 2 weeks now and I like how my truck drives with it. It is more responsive toolying around town and gets off the line faster. I can't give more than an SOP impresssion however since I don't have gauges. In terms of adding power I can't tell that it's added any at WOT but it gets there quicker.

A good test for this would be to set the cruise at 55 on a strait road going up a steep hill. Pick the same point to start the acceleration. Make a 10 second full wot acceleration and see what your speed is at the end of the 10 seconds. I would do this at least four times. Two without the TAG installed and two with. The seat meter might tell you one thing, but a timed acceleration should be a nice definitive test. This is the method that I used when I installed my first EZ and then the 275's and then when I put the comp in. It is a good test and if you throw a load in of say 1,500 lbs it becomes a better test.



A dyno would be nice, but this works just as well because you can and should see a speed difference. without having to pay money for a dyno.

 

[Tardog]

OK, I am always a skeptic until proven different (or I just change my mind) What I don't get is company's showing products or putting them out there with out numbers to back it up. Don't get me wrong, I am a firm believer in companies making things better and I as a consumer benefit from this, But would it be so hard to get one of these things on a Dyno? or other test that we can relate to. Numbers and dyno print out sheets speak volumes to me and others on this board, and I know it is not always the final word. But numbers we need numbers!! (Sorry if it seems like a bit of a rant but it's not meant to be). Cheers,

 

[GIT-R-DONE]

Yeah, I am with Tardog on this one... ... ..... why would a company introduce a product without giving us the performance numbers. I am not saying this wont or dosent work, but, won t buy one until the numbers justify the $$$.

TAG Numbers

Tag numbers are coming as soon as we get some of these testers on the dyno. So far only one 2002 truck has been on the dyno and that was the end of last week. As soon as I have the print outs we will get them posted. Hopefully we will get some more dynos later this week and be able to post more info. next week. Please keep in mind the current Cummins TAG is experimental at this point and the production parts with support rings are not expected until early November 2003.

Will the TAG fit other configurations like Kurt's B1B? The B1B is probably a small subset of users though.



I for one would be interested (and have a KSB1B). Anything to get the air flow more laminar.

Car_nut57,



If you get this before you send the package to me, my turbo is the HX-35 on the 2001 H. O. I am not sure if you knew that or not. Hopefully this will not cause a problem.



As discussed per our conversation, I will base line everything out prior to testing. My goal will be to provide you with about 5 to 6 pages of data points for power, mileage and performance gains at each level of selection from stock with 275's to level 5.

I will also look into running dyno test to back up my G-Tech findings on the street.

Bob Weis

Bob, We have made some custom test TAGs for other turbos such as ATS and Cat, but these did require some machining of the housing to properly fit the material. If you are interested in trying a TAG in your turbo, give me a call to discuss it and keep in mind it may require some CNC machine work for us to fit the honeycomb into the housing.

Dyno Testing

We're having a dyno event in the next month or so and I'm sure we would have all sorts of motor combos with willing drivers. Send us 1 or 2 to Dallas. We'll test them out for you.
