- And what about stress of crank or moving parts WITH a lighter flywheel !
- Does anyone know how this affects the milage in the engine ?
- Competitive engines does not care, as they recieves new parts regulary

- is allowed to spread into other parts in the "block"
- I recall "dampers" are used but do they take care of all vibes?
