Yes: the suspension work and fan shroud are both extraordinary. Both are different from anything else I've seen.
For example: the fan itself looks just like an original Carrera fan. But the shroud doesn't. And it predates the Kuzu shroud by decades.
Let's compare. This is an original:
One of the things that sets off the 547 shroud from imitators is the fan center offset. From the back, it's slightly to the right of the engine and transaxle's centerline.
Now here's Anand's Kuzu-engineered facsimile:
See how clever this adaptation is? The fan itself is dead center, but the shroud is shifted slightly to the left! So subtle I didn't notice until yesterday.
Here's the long-promised CB Centermount overlay by Bic Green. I don't know that this project ever shipped. Someone said @chines1 had one for testing a couple years ago...
This one used a VW doghouse fan with a nosecone of Bic's design and manufacture. You can see it's perfectly centered all around, and the fan is lower than a 547 fan. Still very similar to a real-deal 4-cam shroud on first impression, but not in the same league as Anand's shroud.
And finally once again our new contestant: Again, dead-center. And there's no separate velocity ring. But the fan itself looks "right."
This looks to me like a cross between the Bic shroud and the Kuzu shroud. But keep in mind it's on a Type 4 engine.
