All that inertia is one of the only things that makes my stock 4kq
fast.  Quick shifts from 5000 rpm throws the car forward with authority
that my old GTI never had.

Even the lighter flywheel doesn't totally solve the quick rev problem.
I weighed the crank on the KH motor I am rebuilding and it was 60 lbs.
Now this is closer to the axis of rotation, but still very significant.

I am looking for the 200 flywheel option when the KH goes in my 4kq.
