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?

We have run a lightened flywheel for years. It is not a detriment on the highway, and it makes the initial launch from a stop better.

The downside is you have to use more RPMs and more slipping of the clutch to get it to take off from a stop, which will make the life of the clutch shorter.


I have not found any reason that would keep me from running a lightened flywheel.
