I see that Rotax has come out with a Turbo charged version of the 912 - the 914 which raises the HP from 100 to 115. It looks like the same displacement and probably the same engine mounting.
Other than the cost, is there any reason why the 914 should not be considered as an option for the new breed of LSA. Does is comply with the new rule (naturally aspirated).
Looks like it is 40lb heavier but would provide great power at altitude. A nice trade.

The 914 has a lower TBO than the 912, 1200 hours vice 1500. It is the same displacement as the smaller 80 HP Rotax 912.
Also S-LSA rules require that an airplane with a 115 HP have a higher useful load than one with only 100. Jabiru with their 120 HP engine, but it might be problematic for some aircraft. Don't know if that is an issue for E-SLAs.
At the Sebring Expo, Liberty had a prototype certified aircraft that had the 914. They said it had better high altitude performance than the O-235 they normally use.

The way the Magni is setup it only uses 100 horsepower normally and if you go around the horn on the throttle you will have the full 115 horsepower.
The advantage of the turbo is full horsepower up to the critical altitude of around 10,000 feet. I don't recall the exact altitude. The other nice thing is the computer takes care of the work for you. You don't really need a manifold pressure gauge.
