Allison's has a $ 409 aluminum flywheel for the 850, to increase revs etc. Anyone here buy it and install and can give us an idea as to performance improvement?
 
John Edwards, Fiatnutz on Youtube has one on his sedan. Not sure how it performs and have not heard from John for awhile. I have a stock steel one heavily modified. I think it's about 2/3 the original weight. Took a bit to get used to at first.
 
The car in the youtube video is mine. I wish I could give you a better idea on how it compares with the stock flywheel but I never drove it with the stock one. It does rev pretty freely though. I'm still in the process of gettin my 850 tuned correctly. It was sitting since 1984... it's running now but idling rough. Still working through it all and trying to gain more knowledge. (also that radiator setup did not work out; had to go back to stock)
