Thoughts on Engine Sound at High RPM's (kinda long)

Hahaha, nope, still a mechanical (just as I was two post ago). I have not used ANSYS as of yet, but I do see it in my near future (just for my general understanding of the software). My job provides me with resources if I need any CFD done (i.e. a group of people who do nothing but CFD). I more or less use the results to make decisions regarding design. Keep in mind, I am not coming up with any brilliant, new concepts ( at least right now haha), I follow strict design procedure that has been proven with decades of experience and data.

I understand your point about losing engine response, as I think we all do, but some of use who are not tracking our cars may be willing to make a tradeoff, but first we would have to know what that tradeoff is. Minimal performance loss for decent decrease in vibrations, Ill take that all day, because I dont and wont ever track this car.

However, a heavier flywheel may be way out of the question, I dont know the answer, thats why I postulated the question and asked! Wanted to open it up to others who may have more experience and stimulate some outside of the box thinking. This may not even be an option, seeing as the flywheel seems to be fairly heavy to start with. However, if more weight (like less than 10%) could signigicantly decrease the vibrations and sound, I would be a buyer.
