Got the custom Inconel hot side shield on today and, it fits beautifully!
Was built off a high resolution 3d scan I did on the turbo, directly to a 3d print to use as a templet.
This should also fit a factory 718S, so I will offer these as a product for those guys as well.
If you haven't experienced the FANTASTIC functionality of these units, it is SHOCKING how well they insulate. The radiant heat is effectively reduced by 90%+
I've run countless dyno tests with these, you can literally touch the shielding after. Try that with a uncovered housing - you'll be leaving skin behind! They also hold up to many, many thousands of miles of use without any issues or any signs of wear.
If you want one of these, and it's not currently available for the turbo you are using, feel free to reach out to me. They can also be made to cover exhaust manifolds, downpipes etc.
These are far superior to the soft fiberglass "blanket" style heat shields. They fit much more tightly, work equally well (or better), and are reusable (the soft ones generally fall apart if they are removed after a few thousand miles). They also wont promote a fire if they are contaminated with oil. This does come at a higher price, but I find it well worth it.
Here are some pictures for your viewing pleasure:
