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?

Funny thing is have you ever felt how heavy a 930 clutch and fly is?
If you like I can weigh a 996 clutch and dual mass fly, I'm guessing 30-35 lbs. Raby won't build a 996 engine with a lightened fly, LN will void any support, as well IIRC Jake doesn't build T4's with lightened flys except maybe for some special projects .

Balancing is way more important. Even if you're sticking on a balanced fly that's not a full assembly balance, in fact it can make the balance worse. First spin on a balance machine you might get 500rpm, after balancing it will almost instantly spin at 1000.
Balancing is especially important for stroked engines, as you're moving a lot of weight further out from the center. I have and will never build a stroker engine without a full assembly balance. Factory balance is for a stock engine period, even then I try to talk peeps into a full balance on their engine.
