Pattern Altitude
Non-turbo 200HP, on a 2900# bathtub. It's not complicated. The spam-can competition circles around 2600-2700 gross weight on that power rating, with predictably better climb results, especially when you consider what happens to the 20's useful load when you compare apples to apples and restrict it to #2700.
The SR-20 was a prime candidate for the TSIO-360 imo. I think that airplane would have been popular, even among flatlanders. The problem for Cirrus is that if you start selling turbo 20s that compete with NA 22s as low as the low teens, then you start poaching the customer base from your overpriced flagship. Thence you'd have to make the budget model really underperforming in order to bamboozle the customer into believing the 22 is worth the overcharge, which is exactly what they did. Just like they wouldn't widen the Arrow/Dakota and give it the comanche engine because it would poach the Lance/six300 base post-flooding, Cirrus handicapped the 20 in order to shelter its flagship darling. It's the airframe equivalent to garmin's GTN 625 pricing scheme.
The IO390 seems to have solved much of that, at least on paper... The G6 SR20 seems to be a much better performer considering that it's not that much more than a new C172.
