I've been testing out the Sr22 in the circuit as per the Cirrus Flight Ops Manual and I think the performance is a little out. The feel of the aircraft is great, no complaints there!
According to the FOM, the SR22 should be 30% Power / 15" MP Downwind for 100KIAS. I'm finding it needs more like 44% power to maintain 100KIAS in ISA standard conditions, no wind.
Beginning the descent at the mid-downwind point should be 15% Power and 50% flaps, trim for 100KIAS - with anything other than a very rapid rate of descent you cannot maintain anything like 100kts. It drops to about 78. Adding 100% flaps thus reduces way beyond the 90kts indicated in the FOM for base leg, 100% flaps and still 15% power. These two stages need more like 25-30% power or more to maintain the required airspeed.
Final for the SR22 should be 15% or as required to maintain 80KIAS. This again needs more power to stay near 80KIAS.
Interestingly the SR22 Turbo gives 50% power for Downwind and 25% for Abeam and Base, which is getting closer to what I'm seeing in the non-turbo version of the Torquesim SR22.
