awwww SHIT - I just wrote a reply, then mistakenly erased it somehow... damn computers!!!

Blake, your real name is nested in your profile; I was looking to see what car you had listed, so I could get an idea of what you were working on. So I just threw your name up there. Don't worry about it - I'm on the other side of the globe, and I'm just another clown like the rest of them...

As for a flywheel, I agree; cast iron just plain wrong for high performance, and skip right past the various aluminum alloys; the necessary friction face is a big pissing contest of silly fiddle-fuss hardware. The proper material to use is 4140 Cro-Mo low alloy steel. Buy a short bar-cut of "4140 HTSR" (heat treated & stress relieved) and you can't go wrong; it is available as round bar in increments like 10, 11, 12, 13", and most suppliers can cut you off a 1" thru 3" piece no problem. It comes tempered as spring-range martensite at Rc 28-32, and it holds tolerance very well when being machined. As long as you don't have an interrupted cut, machining it is not a problem. When you see reference to a "chrome molybdenum" flywheel, this is the material they are referring to.
