Surprising result worth noting (Turbo Air Guide)

[BigGunZ]

For those of you reporting "black soot" inside of your intake plumbing... do you have a habit of tailgating? C'mon... you can admit it out loud.

 

[Matt400]

My only fear about the cool blue hose now is the excessive turbo scream that Matt reported. I like turbo whine, but not TOO much turbo whine.

Then you would be ok. I just didn't want anymore noise at all and it was a constant high pitch whine especially while towing that annoyed me. Its possible the TAGIII would quiet it down.

Can't believe folks are still using these restrictors. Have two for 12 valves real cheap

tag 111

Just ordered mine should have it Thursday . If i don't see any change send it back Oo. Oo. Ski

Anyways, my TAG is no longer installed, since I no longer have the o-ring (I'll get a new one). I'm also in the process of re-evaluating my stock intake plumbing and looking at making some changes which might result in an inability to run the TAG anymore. I like the looks of the cool blue hose, but DPP should really consider making one with a TAG permanently integrated in the straight section of the hose... Dave, are you listening?



It will be interesting to see if anything changes with the TAG gone.

I am listening. The Cool Blue hose fits 03-06 trucks and the TAG-III fits into the Cool Hose just fine. The Cool Hose has the advantage of being one continuous hose and is very resistant to under hood heat.



Also the TAG-III has better performance characteristics than the old standard TAG and can be used on 94-2006 trucks. If you would like to upgrade to the TAG-III, we do have a credit for TDR members returning their original TAG in exchange for the TAG-III. Feel free to give me a call.

Hey Ryan, I too liked the looks of that hose and bought one. Cleans things up nice and looks good too but I took it off after just one week of use. The high pitch turbo whine was just too much, especially while towing.



It has some flex plus with the air box rubber mounted I don't see any trouble from engine to fender movements. I would rather use the Cool Blue than a steel pipe for sure but the noise! maybe it could be wrapped with something but then you are covering up that pretty hose.

Did you try the Cool Hose with a TAG-III? The TAG-III should help to reduce noise traveling up the intake tube.

 

[Car_nut57]

It looks like they did away with the O-Rings on all the TAG's. My TAG II came without one. The original TAG had one. I didn't reinstall the O-ring w/ TAG II. See the pictures @ Diesel power products. None of them show an O-Ring anymore.

You are correct, we do not use O-Rings anymore on any of the Dodge applications.

It's been awhile since I have read anything about the TAG III. I would like to hear about anybody's experience with them (especially the 05's) now that there should be a few more on the road.



Also, has anyone taken a bone stock truck and added one these to see what the difference was (if any)?

 

[DPKetchum]

They must work just great. Just like a tornado for gassers!

 

[Money Maker]

But if the TAG is so good I still wonder why it isn't used in a jet intake.

I assume your refering to commercial jets since you seem to have already covered military hardware. Though keep in mind most military jets have to be able to deal with supersonic air traveling into their intakes, those jets use all kinds of trickery to reduce the speed and turbulance of the incoming air.



Commercial jets have very large openings with fan blades exposed a lot like our turbin blades, however there is one component our systems do not have to account for... DRAG.

 

[JApol]

Jet engine intakes do not go through a filter, turn 90* in a big square box, turn another 90* in a roundish tube, go through some air baffles, make another 90* turn in a roundish tube being directed by fins to help the air make the turn and then into the compresor blades. I bet its smoother going over the cascades in a winter storm in a Horizon Air Dehaviland-8 than the intake of our trucks



A jet engine is more like the setup on a sled pulling truck. Look down the intake and what to you see? Nothing but blades.

 

[CBrahs]

I have an 07 with 700 miles on it with auto transmission if you need a test bed for the new trucks. I do have 5 inch turbo back exhaust, 5 1/2 in lift with 37's everything else is stock. I am in Albuquerque and at 5000 feet elevation. My parents are wintering in Prosser so I can have the old man swing by your shop if need be.

Also, has anyone taken a bone stock truck and added one these to see what the difference was (if any)?

I did. I noticed no change in performance. Fuel records indicate no change in economy.

I was reading an article the other day in a magazine that was doing a comparison on stock verses after market intake systems on a 06 model Dodge. They found no advantage over stock and in some cases a loss in HP and Torque. This was done on one truck and the intake was the only mod. I will try to find it again and let every one know where they can read it.

Please correct me if I am wrong but if you increase the intake flow but do not do anything to increase the exhale then you would have a loss in HP/TQ.

 

[Matt400]

No, it was military. I just remember models that have turns in the intake before the engine. I only said that because in theory it sounds like they would benefit if the straight air was so much better.

You wouldnt see max potential, but you should at least see a gain of some sort. I have done research in other areas and with out a potential gain its not worth the money or effort. The conclusion they reached for the 06 was " Dodge had done their home work and produced a very efficient intake system down to the air filter.

 

[Car_nut57]

Air flow is important, but its not the entire story. Air temperature makes a lot of difference as well and the stock box is good for keeping intake air temps down. Here is a little information about that http://www.dieselpowerproducts.com/cold_air_intake

 

[AMink]

I understand the theory behind the TAG, but have some questions. First, how much surface area does the honeycomb take up, and does it actually reduce air flow? EDIT-I found the answer to this in an earlier post. Lots of math!



Other question is a little longer.



I'm thinking that if air was being shoved into the turbo, it would be pretty squirrley, but if it is being sucked into the turbo (which it is), wouldn't it be pretty stable? Kind of like trying to push a rope into a hole as opposed to pulling it through the hole. If there was a Turbo Rope Guide, you could push it in more easily, as it wouldn't wad up. However if you're pulling it, you don't need a guide.



Am I over simplifying this? Bottom line, do these things work? I'm close to saying yes because they are recommended by John Holmes, but I'm having a hard time wrapping my feeble brain around the matter!
