Um, according to the web site you provided, at 8000 ft and 75% power,
the 912S achieves 155 mph TAS, not 200 mph TAS. The 200 mph is with a
different (much more expensive) engine at a higher altitude.

-) the Avion Lightning is one I never heard of.
But even with 120 HP it only manages 150-170 mph cruise?

I suspect that the 914 would have similar speeds at the quoted 8000
ft altitude and 75% power fraction. If you are going to fly high, then a
turbo would probably be appropriate. And the Arion Lightning isn't the
slouch you think it is:

Note the Lightning was traveling at 185 mph TAS at a DA of 3840 ft.


OK, my mistake, I was comparing apples to pears.
Thanks for the correction!
