Butcher crank. Safe or not?

You didn't even read my post, you just responded, what did you expect? Who else have you talked to that has a butcher crank?

I did read your post, i just saw it from the point of view as you just build and tuned the car, you most likely haven't spent nearly as much time it in as he (him being the daily driver). so you probably haven't experienced every bump in the road like he has. But i could be wrong.
I havn't "talked" to anyone that has one. Reason for starting the thread, I've read a few posts scattered here and there in a few different threads from people that have them, they are always either/or.. I know you said you didnt notice a difference, but has he? how does he feel about it? what setup does he have? 2.0, 2.1, 2.3 or 2.4? This might be a stupid question, but could the different strokes have an effect on any of this?

don't upset the wisemen... They know the moderators!

Anyway, I had on in one of my many built 2L motors, they're fine. If your car stalls because if the crank, it's not because of the crank it's because whoever tuned it doesn't know what there doing. The cranks work just fine. Get a fluidamper too...

I know the moderators but I'm not going to report people for misunderstandings, it would need to be a clear violation of the rules.

I've spent almost as much time in the passenger seat of the car as my cousin has in the drivers seat, there are no negative side effects. It's a 2.0 Eagle/Wiseco bottom end, FP2x cams/dual springs, ACT flywheel/2600 clutch. The flywheel has more weight removed than the crank does, we noticed the difference in the flywheel when we installed it.

A butchered 100mm crank would probably be even less noticeable than a 88mm crank. I wish I knew more about physics, but it seems to me that since there is more mass further away from the axis, it's not going to have as much of an effect as it would on a 88mm crankshaft.
