And then I went and looked up Peer Reviewed Scientific Journals on Yttrium Stabilized Zirconia, and it is an effective thermal barrier used in a verity of industries...

It's not a replacement for a heat shield, but it is effective especially for its thickness and resilience to base material expansion.

So yeah. Science Bitch indeed.

 

I am editing this post because it is uncalled for. I have no personal beef with you so i feel its more appropriate to edit my post and remove my comments. I have no need or desire to insult you. We disagree on certain things and there’s nothing wrong with that

 

I did see your original comment and kinda wondered what I had personally done to you. No worries, we all get carried away sometimes.

If you decide you want to look into it more..

honestly, it did make me laugh but then I remember them back from 30 years ago in the local central Florida scene so I might be biased. Yet the way the test was conducted indicated that maybe things hadn’t changed much.

The turbo, manifold and downpipe here is coated in a white plasma applied coating - no cracks - endurance, track only car. I notice one of the indycar parts resellers in the last few years had it on one of the EFRs they were flogging - sourced from Penske most likely - plus the inconel shielding.

The stuff here is not the usual suspect supplied, but it's much the same I'm sure, used in industry, mining, etc, locally for heat control. Biggest advantage, you can touch components without 3rd degree burns a few minutes after shut down. Still use stainless heat shields, air gaps, foundry insulation and ducting. The steering unis, we do run stainless shields there too.....grease in the needle bearings is probably the next thing to depart after the accordion boots cark it.
