Inconel heatshields
 
2 Attachment(s)
Hi all,

On the topic of heat management, preventing the LIM from getting heat-soaked as quick/much, and with a dusting of 'cool' (ambiguous) on top; would there be a major benefit to running inconel heatshields as shown below over just an aluminum plate between the intake and exhaus manifolds (with or without reflective tape).

I personally love the look of this, but if the benefits are minimal i'd not invest

cheers!

edit: FC, non-boosted application, half bridge n/a on standalone

Inconel's main advantage is that it doesn't lose strength as much when it gets really hot. For a nonstructural application like a heat shield it makes zero sense.

If that shield really is Inconel (I doubt, it's not all that malleable) it probably cost $1000 in materials, too!

Plus if you need something with higher heat resistance than simple aluminum, you're doing it wrong. Air is a wonderful insulator, the purpose of a heat shield is to not just prevent radiant heat from heating things, but also to stop hot air from around the hot thing from heating up the colder air around the thing you don't want hot. With that said, with the airflow you should be getting through an engine bay and the relative openness of a non turbo on that side of the bay, you pretty much don't need a heat shield at all.

Okay, well.. any proper performance guys wanna chip on what this stuff is then? Its pretty prevalent on modern day cars like higher grade Audi's and such 🤔

Anyways, Peejay, I thought any form of shielding against radiant heat from the header would be a good thing, and this looked kinda neat and contemporary, that's why i asked

Thx for the input! 😁

Looks like stamped aluminum (or aluminuminum), a pretty standard heat shield material used by everyone in the past ten or twenty years. I have a very large piece that I scavenged from the underside of a Ford Focus, and part of my radiator fan shroud used to be a heat shield from a Mini. It's very formable by hand.

Peejay,

Thx for sparring with me, you were correct, after some googling it turns out the stuff you see on regular civie cars is indeed dimpled alumininiminum.

Now i know its affordable, im deff. gonna get me some 😎

There are inconel versions you can put directly on exhausts. Obviously more expensive.
