And no light piston twins is required to show
positive single-engine climb gradient during the certification process. The part 23 aircraft only have to show
steady climb gradient, not a positive one.

Both Thielert TAE-125 and AustroEngine AE300 turbodiesel engines are normal turbo engines, they aren't turbonormalised. In TAE-125 the manifold pressure at takeoff power is about 2.3 bar (~ 70"), which is approximately the same as in car turbodiesel engines. The catch is that maximum load (100%) can only be achieved up to 5-6 000ft, where as for example in Seneca (TSIO-360), you get maximum brake horsepower at 13000ft.
