I've read a post on the Focus forums of a guy who had a aluminum flywheel who went slower in the 1/4 than with the stock flywheel. Lighter flywheel sounds good, but in accelleration, the heavier flywheel may take a bit longer to spin up, but when it's spun up it uses it's heavier mass to help keep it moving and you'll accelerate faster than with a lighter flywheel. It's all in the momentum, a heavier flywheel has more.



and that's the never ending debate on go lighter or stay stock that is talked about with every car.



I had alittle over 3lbs shaved from around the center of the flywheel. Made (I think) a very slightly noticable difference in 1st gear, no changes anywhere else, not that I was expectinh much. But I didn't want to go with a full light weight flywheel, I wanted to keep as much rotational mass along the outer areas of the flywheel as possible.
