Cool Blue Hose & AFE Stage II Intake System

[nauidvr1]

Question for other member that have performed this MOD.



I am interested in the Cool Blue Hose (actually in gloss black) and want to install it on my trucks. However, I already have the AFE Stage II intake system. I was wondering how the Cool Blue Hose attaches to the AFE PG7 filter, or if it even does in a mechanically sound mannor.



I was thinking that if the Cool Blue Hose would not attache directly and mechicanically sound to the filter, that a short piece of 4 inch? metal tube (like SS Exhaust pipe) between the AFE Filter and the Cool Blue hose might do the trick and then just use a clamp on each side.



So those that have done this or have a Cool Blue Hose - How did you do it????

Better get a measuring tape out... ... ... ... . my AFE inlet is more than 4"

BTT -



Back to the top - 60 views and only one partial answer, thank you for joggin my memory on the diameter - and I will go measure it ASAP.



I was hopeing that someone, that has performed this MOD, would chime in to assist me on this.

I am very happy with my AFE as is no need to change it You will find the hose will be too short and you will have to make a cone to increase the diameter of the tube. To let you know, the tube is not a restriction,the turbo inlet is. All this has been tested on a flow bench already.

Bob4x4,

Thanks for your info. I also like my AFE system, but I was looking for a way to lower (or keep as low as possible) the incoming air temp, especially while towing in hot weather. It has been tested that the Cool Blue hose only allows a rise of 5-6 degrees over ambient while the plastic AFE tube has increase of 41+ degrees over ambient temp. I do understand also, that the underhood temps will be higher than ambient, but the cooler you can keep the incoming air to the turbo the better (denser) the charge air.



As an added benifit, by changing out all my hoses to the silicone, they should last a life time at the pressures I am exposing them too - i. e not everything I have on the truck is listed in my signature, for privacy reasons ofcourse!

I would be interested to see that iat testing. I have a monitor on my truck for iat that is on all the time. I regularly see about 10 degrees above ambient with the AFE.

I have all silicone hoses on both my trucks also.

Bob4x4,

I searched for 3 hours tonight to find where I that read the test data at, and for the life of me, I can't put my finger on it now. That is usually how it happens, when your looking for it - you can't find it, when your not - it's right in front of you.



I'll keep looking and post up the testing data. I do recall that it was an independant (TDR member I think) that had done the testing on several torque tubes, stock, metal, plastic and such.

 

[Bob4x4]

The air flows so fast through the intake tract I don't see how any material will be able to transfer any significant heat as it passes through. I have asked this question to a fluid dynamics engineer and he agreed with my general thinking.

I agree that the tube temperature probably has very little to do with the air temp at the intake. I also think the turbo compression will probably heat the compressed air to about the same going into the intercooler anyway. Of course I could always be wrong.
