I recently read the Mooney Bravo (Mooney's single engine turbo charged prop) has a max operating altitude of 25,000 feet. My question is, with an operating ceiling that high, is the Bravo pressurized or is supplemental oxygen required? If not pressurized is the O2 a standard feature on the Bravo? How does the system work. Are there any pressurized singles out there besides the Pilatus? Maybe the new Lancair which has similar operating specifications to the bravo. Thanks for any help.

supplemental oxygen is required for the pilots above 12000 ft, and recomended over 10000. also, if there is only one pilot on station on the flight deck then the other must be on oxgen until the other returns.

The only piston singles that are pressurized are the Cessna P210, Piper Malibu and Mirage, and the Mooney M22 Mustang.
The primary problem with the P210 was that the fuselage was not designed to be a pressure vessel, thus being a sub-optimal platform to pressurize. Somehow I remember reading that the max pressure differential for the P210 was around 4.5, basically giving you a 10,000' cabin at FL210.
The Malibu/Mirage was a ground up design and thus optimized for pressurization. As far as I know it can maintain a 8,000' cabin up to FL250.
Don't know much about the Mustang, though I do believe it was the first one of the three to come out. Not many were built however.

There are a couple pressurized singles in addition to the pilatus PC-12. These include the Socata TBM-700, and the Malibu Mirage. All of these aircraft are powered by turboprop engines, I think all use a derivitive of the PT-6.
Most of the high end singles that are not pressurized come with an oxygen system as standard or optional equipment today. If not, you can buy a portable system that will do the same job. In most cases though, it strikes me as being impractical to fly a piston single that high. Aside from mountainous terrain, you really don't bennefit much by taking the time to climb that high. If you're in a hurry, you might get a better tailwind but sitting up there for hours on end in any single, most of which don't have good cabin heat systems, is not my idea of a good time.
