After the 15% discount which I should qualify for, it would be about $150 before shipping and taxes.

I'm pretty sure my current flywheel cannot be turned down anymore.

Forging is a much more expensive process. I can understand why factory would use it from a product liability standpoint (also may use same forging for higher HP applications?).
Depending on the alloy and impurities in the metal I could see how a cast part could become a grenade if quality was poor. However, if a hardening process was used on a high quality casting, at least for a low HP application it may be appropriate? Because if it's aftermarket, I'd bet it's not forged due to the cost (and what you paid).

What are your thoughts?

My thoughts are this:

High quality castings....centrifrical or other methods are very expensive nowdays and a tyoe iv flywheel...in my mind wouldn.t be justified

They used investment castings in the old days prior to the advent of larger billet steel sizes and cnc equipment.

I highly doubt that the part is cast....it is either machined billet steel or forged. Most likely forged.
