It looks like a flywheel substitute for a redrive. Please enlighten me here.

I first tried to make a casted aluminum piece. That failed. I was able to make several small parts, but trying to cast this big plate resulted in a paint can sized chunk of aluminum stuck in the furnace. I ran out of fuel at just the wrong time. So, I ordered a 12"x12"x1.5" block of 6061-T6, chopped off the corners, chopped off then new corners, tapped the center for a 1/2" bolt, and started turning. The pile of shiny stuff is aluminum swarf. The lathe was kicking it out like a web out of a spider. The Harley-Davidson rotor bolts onto the front. I turned an alignment tool to center it. The clutch plate snaps (literally clicks when it goes in) into the back of the plate, and the whole assembly snaps into the flex plate. The only step left is to rivet the impeller blades onto the plate, fill the pump body with foam and carve a volute, then glass it in.
