Now, I am at the extreme end of the spectrum, 489 Ci BBC, but given the choice, today I honestly believe it is easier and cheaper to run a pair of hair dryers.

Exactly. Blowers are great for lower power levels...but when you really start asking a lot of them, they slip or break like you said, and they put a LOT of stress on the front of the crank, causing breakage or crank flex.

A turbo engine that makes 1000 hp at the crank makes 1000 hp.

A blower engine that makes 1000 at the crank, might really be "making" 1200 hp, with 200 hp being consumed to turn the blower, to net that same 1000 at the crank. The bottom end of a blower engine takes more of a beating for sure.
