The problem is not the machining, it's how cast iron behaves. A few quick points, do I doubt it matters
Cast iron VS "billet". A cast iron atom have a much weaker link to it's neighbor compared to a "billet"
( forged ) iron atom. This is reflected in how a cast iron and a "billet" flywheel behaves. Cast iron will not
stand up to serious abuse. Please read my first post in this tread, it's fine behind a stock engine with a
stock clutch, everything else I would not recommended, nor risk, and I do speak from experience.
Let me try an analogy. A wooden boat is a vessel floating on water, the problem is it's not homologous,
I'd call it a collection of pieces of wood floating, ( more or less ) in the same direction. The different
piece of wood is not to well linked to it's neighbor piece.
A fiberglass boat is homologous in that the hull is made in one piece, the different pieces
( fiberglass tread/mats ) is "linked" better to it's neighbor
Why would car manufacturers use forged "billet" flywheels on some models if a cast iron flywheel will do ?
Ford with all the Sierra and Escort Cosworth engines and BMW with the M series engines comes to mind.
Finally, can you do me a favor and read up on cast iron VS forget iron behavior and characteristics ?
This is not me being difficult, I'm trying to save somebody else from a lot of pain. What you do to yourself
I can't do anything about, but you trying to pass off a cast iron flywheel as "just as good as a billet,
forged flywheel" I will not have any part of, and I will speak up against it.
