heat shielding/wrapping

[staubs]

Anyone have experience with heat wrapping their cars? I have been thinking about doing this for a while to help reduce heat soaking. The parts I am considering wrapping are: intake y-pipe, turbo inlet pipes, turbo outlet pipes to intercoolers, apr bi-pipe, and ssac down pipes.

i vote just wrapping the down pipes i think the other pipes, i.e. bi pipe intercooler piping should be left alone to dissipate heat on keep in heat.

+1 for the SSAC downpipes. Even if you're retaining your heatshield, these are made with a fairly thin metal and should be wrapped regardless, IMO.

I have never seen any of the other parts you mentioned wrapped in header wrap on our cars or others. After all, it's called header wrap for a reason. If you're concerned about heat dissipation elsewhere in the engine, consider having your exhaust manifold ceramic coated (generally reserved for a high performance application). Other than that, I would suggest leaving things alone.

I hate getting fiberglass shards all over me when working on a car that has heat wrap.

Ceramic/swain tech coating is the way to go. My b5 track car is getting my 605 hot sides ceramic coated with a turbo blanket and the rest of the exhaust is getting the swain tech treatment

I'm all for the coatings and I would have had my frankenturbos and inlets coated ,but it would have taken a few weeks to get that done and I needed my car. I can easily wrap the down pipes using my neighbors car lift, but I'm not pulling my motor again just so i can coat the manifolds. I had the Idea of heat wrap from a build thread I read a while ago where a guy with a red s4 from colorado heat wrapped all the same pipes on his rs6 turbo build.

OP, were you thinking of doing something like this:

That ^^ and regular header wrap on the exhaust down pipes

And thinking of getting these for the turbos

I had always been curious about if there were any mild gains to be had from gold heat wrapping some of the intake parts, but have not seen any data or info on it

I used the DEI Titanium header wrap on my downpipes, it had a higher direct heat rating, doesn't require "wetting" the wrap to install, and doesnt require any special coatings afterwards that other header wraps recommend/require. I ditched the factory head shields at the same time, and I have zero complaints, things stay 'relatively' cool back there (you can work around them shortly after cool down without too much radiant heat from them), and the subtraction of the factory heatshields makes working around back there a breeze. Not sure if it helped insulate the cabin noise at all from the thinly walled downpipes, but i think my car is pretty quiet inside compared to others' videos, so maybe it did help.

Here is what i am pretty sure i used:

Turbo blankets, ceramic/jet hot coatings, and header wraps all work well to keep heat where they it's supposed to be. Mostly to utilize all of the thermal energy possible. Wrapping intake piping/intercooler pipings with heat reflective wraps will help avoid heat being absorbed.

Unfortunately lack of space and air circulation will always hinder heat soak.

Doing things to prevent heat from escaping and being absorbed will help but you still need a way to get the ambient air that's stuck in the engine bay out and replaced with cooler air.

The OEM belly pan actually helps with this. Venting the hood properly is another way to get excess heat out, along with ducting to draw in cooler air.

I hope this helps!
