I may make a really heavy shop clock out of it.
Shop just emailed, they're going to make it right. I'm going to bring them a spare flywheel tomorrow. Will make sure to mention the radius to them, too.
A shop that does high performance automotive work would never have done that. I hope they do a better job the second time around!
I'm semi fearless having run a number of lightened OEM flywheels but that is pretty skinny around the bolts. You'll be good when they do the next one. Big fan of saving the rotating mass on low power animals.

This is a pretty good sized shop, they have around 100 engines in process. Hundred of reviews, mostly good. Everyone screws up sometimes. I'm willing to give them a second chance.

The stock flywheel is something insane, like 15 kg. That was basically how they made old non-balance shaft pushrod 4 bangers not resemble cement mixers back in the day.
There are some downright frightening lightened Volvo B18 / B20 flywheel pictures out there. Most extreme I've seen was claimed to be around 5 kg! Don't try to get that car going from a stop on an incline with 4.10 gears!
