Real stats on engine failures?

In a SE airplane w/ an engine powered vacuum pump and w/out a backup

gyro failure in a minute or so.

Not true unless the engine seizes. If it keeps windmilling, the gyros
will keep spinning.

I could be mistaken, but I don't believe windmilling will
produce sufficient vacuum to keep the gyros spinning reliably.

FWIW, my engine at idle won't keep the vacuum gauge in the green, but the AI
and DG appear to work properly. Would a windmilling prop produce as much as
1,000 rpm?
