Rotax 914 Turbo

How come? Are the turbos really unreliable?

The 914 has extra complexity (more points of failure, as seen above), greater weight (16 lbs), and greater cost (about 60% more!) than the 912 ULS.  The 912 ULS, a newer design, has nearly equivalent power, except at higher altitudes, or for the 5 minutes you are allowed to go past the detent and go "full turbo" (115hp) on the 914.  Since I don't often fly at high altitudes, or on short fields, it was an easy choice for me.

I always thought the lower compression of the 914 would make it more reliable in spite of the turbo. I guess I was wrong.
