exhaust and turbo wrap?

[Jed]

After some research I have tried wrapping about 2 ft of my exhaust down pipe from the back of the turbo.

The idea as I understand it is to keep heat in the exhaust side of the turbo so it is more efficient. (more heat =more pressure =more spool)

The question is what can I hurt by doing this?



The results are very good; faster spool up, a little more boost, cooler egt. I am sure that some of this can be attributed to cooler under hood temperatures being sucked into my bhaf.

I have not seen any references to this before.

Would I also benefit from wrapping the turbo or would I be asking for trouble.

Thanks

I thought the benefits of exhaust wrap were pre turbo and the housing itself. You gain energy from the heat that is going to the turbo. Not sure the benefits of the downpipe.

try wrapping the manifold that is where you should see the gain in spool up

I had to wrap my downpipe cause the firewall started on fire.

The only downside to the use of exhaust heat wrap is that it tends to promote rust. I wrapped a set of Stan's headers on a modified IHC Scout and they rusted through in 18 months. I have several friends running Stan's headers for years and mine are the only one's to rust out.

Thanks to all who replied.

I think that most of the benefit is from reduced under hood temps. This should help with summer driving with ac since the 4" pipe is very close to ac parts.



I think I will hold off on wrapping turbo and manifold because of cool down during summer. Right now it is not much of a problem, I just have to idle a bit but it has been rather cool for so cal.



I think that I will look into a cool air intake or at least a heat shield for bhaf. I may follow this up with an intake horn such as the stainless one available in the marketplace section.



Thanks

its not rust. its thermal fatigue. header wrap is grat stuff for race cars, but can lead to premature failure.

Hard to belive that the stans headers were the only rust problem on a IHC scout...

had a traveler one time whent through a curve near home leaning on the door...

IH sorry door came open and the seat i was seatbelted to had rusted out around the base so me and seat whent out the door

only thing that saved me was I had my right hand at 2or3 oclock on the wheel and when I started out the door I pulled the wheel a good half turn to the right so that the unmanned traveler missed my body, just ended up with some road rash.

ain't GOD good ???

Check out ATP
Advanced Thermal Products
I ran into Tim the owner about 8 years ago when he did some thermal wrap for a generator exhaust I was installing on a project, I'm a GC.
My truck was a couple years old at the time, he pulled up in a Dodge 3500 and I kinda ignored it. He asked me how I liked my cummins and I said I loved it expecting to get in the conversation that normally follows with gas owners. What he said was me too, great engine. I turned and looked closer at his truck, it was a cummins but I didn't hear it when he pulled up. Very impressive.
I've always liked the NOISE my truck makes and the expense of the full kit always seemed like way to much. But I'm thinking about getting the exhaust and oil pan portions of the kit now. must be getting old

So is there a downside to using ATP products. I mean obviously some services and engine component replacements will be more intricate, but what about increased temps affecting parts and overall longevity??

Tim of ATP installed the entire kit on my truck 2 years ago; oil pan, valve cover, exhaust manifold and turbo heat shield. The oil pan and valve cover reduced engine noise while the exhaust and turbo wrap reduce engine bay temperature. I have noticed any downside with ATP products except the Now my CTD sound like a Prius. :-laf

What about servicing different compnents. . does the ATP cover come off for a valve job, etc??? And then go right back on again??



I like the idea of a quieter truck.

Yep they are removable as they are held by friction (tight fit) and safety wire. You've seen this old thread you you posted on it. https://www.turbodieselregister.com...on-discussions/200758-quiet-your-ctd-atp.html

It is wired on, if you are a shade tree mechanic then you can probably do it yourself.
I think some mechanics would look at it and tell you "have it taken off then I'll do the work".
