The Ford Barn - View Single Post - When going for SCAT crank should you lighten flywheel? If so, how much?

just my $0.02

The question should be what is the intended purpose/use of this vehicle?

Some of the opinions here are to change the characteristics to make it easier to drive, higher performance and even just to keep it stock.

Having the flywheel too light can make driving a heavy car a little more difficult requiring slipping the clutch more and feathering the throttle. Some may or may not want that.

Depending on the modifications to the engine, the best you will get is a compromise between simple to drive and more temperamental.

If you are involved with a club, take a few test rides in cars with some of the modifications to get a feel. J

FWIW, yes, I have had a couple broken SCAT cranks come to my shop. Obviously abused and well, not the correct application.
