I'm just wondering about this product. Has any one ever had one or have one now. Personally I think that it would restrict the air flow into the turbo but then again I don't know much either. So any one who has used one please let me know.

A great paperweight, possibly a good sinker if you fish....It also might fly well from a skeet thrower.

Honestly, that's a heck of a lot of uses from just one little product. Seems like a bargain!

 

Try a Google search on "honeycomb flow straightener" - which is what the TAG is. The engineering standards governing installation of the industrial engines manufactured by our company require 5 diameters (5d) of straight pipe before the turbocharger inlet(s) to ensure non-turbulent flow. Should this not be possible, flow straightening devices must be used.

Obviously, the inlet duct used by Dodge doesn't meet this requirement, so the 3rd generation trucks use turning vanes to reduce turbulent flow into the turbocharger inlet. The TAG serves this same purpose in 2nd generation trucks that didn't use the turning vanes.

I bought the TAG for two reasons:

1. To reduce turbocharger instability that I was experiencing at high accelerator pedal positions around 2300 RPM in 6th gear when towing uphill.

2. To reduce turbo whine which becomes objectionable after hours on the road towing our 5th wheel.

The TAG eliminated the turbo instability and reduced turbo whine by probably 70% to 80%, so it did what I bought it to do.

All it did on mine was quiet the turbo down some which is all I wanted. A ksb-1 with a scotty 2 with the hole cut is a very noisy turbo.

 

I did a little reading and discovery also. Installed the TAG for all the reasons mentioned by RustyJC. I also e-mailed DC engineering and asked the reasoning behind the entire structural design of the intake with regards to the vein air guiding system and the silencer ring. Their reply was that the veins helped to control turbulence and the silencer ring , while it does serve to cut down on turbo noise, actually kept the incoming air off the extreme edges of the blades, which tended to create a better balance of air pressure against the blades. BOTH the veins and the silencer ring INCREASE the life of bearing wear in the turbo with regard to balancing the inlet flow against the blades.

As I considered the honeycomb structure of the TAG, my only thoughts were that it provided even better, more efficient air direction into the turbo OVER the stock setup. I also noticed that after the installation of the TAG my egt's were lower. Win-Win.

Is this TAG easy to install, uninstall??

The TAG is easy to install, tried it on mine and really couldn't tell any difference in power, but I lost solid 1.5 mpg!

 

Im thinking that I might try it, just to reduce turbo noise while towing, but otherwise remove it for everyday use,, thoughs on this?

Kevin

 

Thanks for all the info guys! But keep it coming!

 

The tag II works good on my 06 I go up hill on the highway with less boost, smooth take off all up the power band. it does work
