914 vs 912

The 914 is Turbo. The 912 is not.

The numbers you cite are for the the 912 UL (and A/F).  The 914 is essentially the turbocharged version of it.

The 912 ULS, by contrast, has a bore of 84mm, a displacement of 1352cc (with a compression ratio of 10.8:1), and is rated at 99hp.

Thanks, but 914 Turbocharger applied only on 115%.

Where as throttle 100%.turbocharger Applied ?

Rotax admin requested for clearfication .

Have a look at the 914 Operators Manual (  see https://www.rotax-owner.com/en/support-topmenu/engine-manuals#914-series-engines   )

Pages 2-2, 2-3 give the take-off vs. continous flight power ratings.

Also, sections 3.6 through 3.9 of the same document give further insight.
