There are certain set-ups were it would. 8000rpm low geared race cars.

I researched this topic very heavily last year and asked the opinions of some very smart guys and they all said I would run slower.

I then Googled the hell out of results for light weight flywheels and I found an article that totaly made me against doing it. I found a post were a guy built his motor with a lightweight flywheel and was unhappy with his 1/4 mile times. Thinking it may be the lightweight flywheel he reinstalled his stock flywheel and cut a much better 60ft and picked up 2 mph cause the rpms didnt fall so bad betwen shifts.
