Good point, David. Just the fact that there is a dissimilar metal interface is going to complicate issues. I'm running Al flywheel on NA app but may certainly rethink this for turbo app. So the question of weak point probably comes down to the durability/thickness of the steel working surface. I wonder what kind of mechanical contact the two materials have, though I suspect its just two machined smooth surfaces that are attached with fastners.
I wonder if one increased the surface areas and maximized the contact....
