I’ve been the happy owner of a Lancair 235 with an O-235 L2-C for 10 years, and find the power quite adequate.  The 235 aircraft is a bit lighter (mine is 945 empty) than the 320 or 360, and with a MT electric constant speed prop, climbs at 1300 ft/min and cruises at 195 mph (25x25, 6.5 gph).  I agree that with a fixed pitch prop, takeoff run, especially at higher density altitudes is a concern.  I guess if you are comparing to a 320 or 360, the performance is poor, but if you’re comparing to almost anything else in the GA fleet, it’s great.  I would not suggest putting a 235 engine into a heavier 320 or 260 airframe however.  The 235 will be more restricted in terms of baggage and passenger weight.  I weigh in at 170, and I’m fine with passengers up to 215.
