Ok, I'll try this one more time and then I'll stop since i don't want to clutter Josh's awesome thread with inconsequential banter.
Second word, post #44 - PROPER. That means the ENTIRE rotating assembly, with flywheel, clutch, and crank pulley. Once you resolve the balance issue(s) in your target RPM, the flywheel/crank pulley will do no damage to your pump.
Next - even the guy whose opinion you so dearly embrace says that a proper lightened flywheel is CNC machined, which Josh's IS. He was probably dissing on some of the ClutchMasters sintered iron FWs, but even those will work fine when properly balanced.
Finally, you're making your argument with a car where oil pump failure is a known issue - here is a quote from the very website your source runs (though I am usually a bit suspect when someone makes a claim about a product whose replacement he's selling):
Both of those statements (going past redline, and significantly increasing the torque output of the engine) will take the balance out of the range it was designed for (not to mention that with age it will naturally become unbalanced due to uneven wear of components).
How does hitting a flywheel with a hammer (while stationary) verify its resonant frequency under load at full tilt?
Most race engines use solid crank pulleys and light flywheels. You might want to stop by their shops to tell them they're overrated.
