Pros/cons of lightened flywheels on stroker engines Options

[Tdskip]

Good morning. On big Type4 engines that are going to be used on the street, it appears that keeping a stock flywheel is a plus for drivability but I’m also wondering if the bigger engines have enough torque that they can handle it lighter flywheel for a bit more zing of an experience.

The one that was on this 2.7 L motor I’m sorting out was shaved down to 12.3 pounds which seems a bit to light for street use.

EDIT - did some researching it appears that too light of a flywheel will make the car a pain on the highway, so maybe just stick with stock weight?

Correct they are also known for when the engine spins down at a stop light the motor might die and you have to restart it. I remember that from my bug days with lightened flywheels.
I thought the highway issue was hills. Its easier to keep a heavier flywheel spinning on a hill or grade.
The advantage of a lightened flywheel is they spin up faster.
