Has anyone had success or improvements using the TAG honeycomb insert to direct air flow into the turbo at a perfect perpendicular angle? They are claiming quicker spool up and more horse power. Even drop in EGT's. Any help or feedback would be great, positive or negative.

 

Spend your money as you wish, but the "tag" reminds me of this little jewel. I like to think of it this way. With the enormus competiton between engine mfg's to make the most fuel efficient engine with the lowest emissons wouldn't you think they would have already installed these things? The "tag" claims IMO if this was the case why did the engine mfg's spend billions to meet the new standards?

I could be wrong but......

 

Try a Google search on "honeycomb flow straightener" if you want to determine if the technology is hype or not.

I bought my TAG I (1.) to correct a turbo compressor instability problem when towing and (2.) to reduce turbo noise after installation of the BHAF. It has done what I bought it to do.

Actually, Dodge did address the situation when they added the turning vanes in the curve in the inlet duct of the 3rd generation trucks.

I have had two TAGS, with different turbos! Like them.
Quietier (which means more efficient, IMO)
More responsive spoolup, on a big single turbo
Requires 2-3 less psi boost to maintain a set speed when towing or climbing steep grades... which also says to me.... laminar air flow and efficiency.
Not an earth shaking, real noticable kind of difference, but it's there.

My thoughts, too. Noise is energy. That energy has to come from somewhere, at least according to all the science education I've been able to get thus far.

I'd love it if they had TAGs to fit the bigger singles-- like the 66-class turbos. I think they would complement each other nicely.

I had one with my KSB-1 and it quietened it down a lot. It works pretty good. If you hold it in your hand and blow across the top of it you can feel it straighten the air out when it hits.

 

Does the silencer ring have any effect on the TAG? Is there any difference with or without it?

 

The TAG is designed to fit up against the silencer ring. Not sure, but possibly the silencer ring is the only metal in there which would act as a stop for the TAG. It's too cold here for me to go out and look.

I don't remember what the effect was when I installed my TAG-2, it was a long time ago. I do recall it wasn't dramatic because I didn't have my camper on and the benefit is supposed to come with a load and higher boost.

 

Not a big step for a machine shop to open up the S300 turbo throat a bit to fit the Tag I. Worth doing IMO.
The closer the TAG gets to the compressor baldes the better! But I have not done it yet on my secondary turbo. Mine rests against the front edge of the turbo... held by a clamp on the connecting boot. The noise reduction was still very noticable.... enough so that I reopened my Scotty II cowl hole.

TAG yields lower peak power on the dyno

 

I have a TAG in both my trucks and wouldn't be without it.
Where you really see the difference is loaded or towing when you are running 20 plus psi boost for miles on end. I recommended TAG to several friends who tow heavy. Every one of them says they get better mpgs in hilly terrain when the boost is high than they get on the flats.
The TAG will work without a silencer ring but it's sort of senseless since the TAG will quiet down the turbo whine anyway. The TAG is held in place inside the intake hose.

If you're just racing between traffic lights with no load a TAG isn't for you, works best highway cruising with a load.

 

Sounds to me like the Tag acts like a restrictor plate. It chokes the turbo a little so it makes less boost and lower cylinder pressure. Any thoughts? Why else would it make lower numbers on the dyno according to ?? Member. The Tag website shows an increase in HP, but only show it with a Banks Garbage Tuner. Does anyone have real numbers, Dyno or MPG?

 

I ran one with the stock intake hose and found when loaded, it pulled better on the hills. It did seem to make the spool up when empty a little jerky. I changed to an AFE torque tube and the Tag doesn't fit the same. I've got to get a longer lower connector boot or modify the torque tube.

 

Nope! Takes less boost to do the same work! That equals greater efficiency (more power to the ground) in my book.
I've experienced no lower #'s at the 1/4 mile track with the TAG. Dyno results...unknown.

I just saw this thing yesterday and was going to post the same question, but you beat me to it. Glad to hear some real feed back.
