To wrap or not to wrap.
So I have been thinking (Weird huh). Is warping the exhaust manifold/down pipe/blanketing the turbo, beneficial? This may centralize the heat but, does it help a performance power-plant in the EGTs? I am confused by the information. thats why I ask the question "To wrap or not to wrap"? I read and talked to Bruce at Pittsburgh Power He says (I am paraphrasing) that it helps lower EGTs by increasing the velocity because the heat energy stays in the exhaust manifold and housing of the turbo where it can make the most boost. I have also been told by some of the locals here in redding that it is not needed, they say just get a better flowing exhaust and turbo, combined with a good flowing intake system and your set from EGTs (this is with the understanding of a slightly modified street/tow rig not a true performance truck). I am leaning towards Bruce. I just wanted to read some opinions on the subject. While I am at it, how about wrapping the intake from the filter to the turbo? Then from the air to air heat exchanger? I know, I know, it's an overkill idea, but just another thought that needs some experimentation. Just to see if there is any change in performance at all, I mean even if it is just small. if there is no change then it was an idea that did not pan out. Thanks again for allowing me the privilege to start another thread.

Heat = Energy.... The more energy you can put from the motor through the turbo the better spool and more or less the more boost you can make.....

Diesel motor needs 1000* air to be efficient & combust/fire ect but... Drop ambient air temp 1* and gain a whole ass load of power (100+ HP) |
Thanks for posting Brice. I Knew you would help confirm my info. :c:

totally thought this thread was about something else.

i tore mine off an painted it with heat resistant paint
|
for me wrapping a truck like a body wrap
|
Please take the poll! while your reading. :tttt: :bat:

I was thinking "Is this girl hot enough to risk it and not wrap it?"

LMAO

Wrapping the exhaust also depends were you live. Humidity or rain does soak the exhaust wrap with water and even if it evaporates real quick it will accelerate corrosion if stainless isn't used in the dump pipe.
High combustion temps behind the turbo keep up the speed of the exhaust gasses resulting in a better scavenging effect. Resulting in lower backpressure and better turbo spool-up. In front of the turbo it definetly keeps up speed and lowers underhood temperatures drastically. Is it measurable? In a stock engine? Barely not. Overall losses are to high than to expect any gains. But the overall mods will sum up. I wrapped mine and I did it to lower underhood temperatures and to release the intake from the radiant heat. Performance gains? Not really caused by the heat wrap... Wrapping is more a gasser thing because effi is a lot less and heat in the exhaust rises up. The advantage of a ball bearing turbocharger will have way more effect than an ordinary wrap- or different expressed: a wrap won't turn the performance of your ordinary turbo into a ball bearing unit... Wrapping the intake? Hell no, just make sure you get fresh ambient air from the outside. That means no open air filter. BHAF with a sealed box and large openings to the outside to ensure fresh , cool air supply. Wrapping the exducer housing? Seriously not! |
I had to wrap a little of mine but thats because the Ford A/C box is gettin pretty well acquainted with the turbo. when it comes time for a bigger turbo/twins its gonna get interesting.....

I'll be wrapping my manifold and hotpipe when I add my S400 this weekend. If I had exh housing blanket I'd put that on too.
|
:tu: hell ya, take some pics :pca1::c:
|
I'll try to get a few pictures in for sure. Planning to get it all done this weekend.
|
This is good stuff! thanks for posting pics RA
|
i never will. i've seen some exhuast wrap, though it looks cool, the pipes turn brittle really quick. lean on them to do some work, and they bend. took the wrap off, and the pipe was flaking apart. it was a gas motor, but it sticks with ya.
|
Sorry I have no pictures from the work done this weekend. Time was tight and little extras like that would have put me too far behind. I still have intentions of wrapping, and will put pictures up when I have them.

To wrap or not to wrap.
I'd pop for ceramic coating if it was me. Yeah it's more pricey but you don't realy have to worry about them. Got ceramic headers on my 96 dodge and like them. Either way I don't see it being a bad thing. I'll be coating my manifold, turbine housing, and maybe even the downpipe when I get ready to change a bunch of stuff out. That's just me though.
|
thats the way to go IMO as well and its not too bad $$ wise either I dont think for what you get
|
Anything you can wrap/blanket will help. There are multiple benefits, besides lower underhood temps, you lower intake charge temps, faster spool and lower EGT's. The bigger the turbo's the more pronounced the results but even stock turbo trucks there is a noticeable difference in COVERING JUST the exhaust housing, leaving the manifold and downpipe exposed. Anyone who tells you differently or that it doesn't work on a diesel more than likely hasn't done it.
