With a maximum continuous RPM of 2475 I cruise my C90 at 2300-2350 which leaned out at around 3000ft gives me about 100kts and 17-18 litres per hour in my D117. It has the standard C90 Jodel Evra prop and although I have never measured T/O distance, I have comfortably flown into and out of 300m in nil wind. I don't think I would be happy in anything less.
