Also, is there a rule of thumb to compare the new 135hp Diesel to 160hp or
180hp AvGas engines? On the face of it, it looks like 25-45 fewer hp with
the Thielert.

The difference is I think the propeller that comes with the Thielert -
it's constant speed, so all things remaining equal you get more takeoff
thrust per horsepower.

And you keep that power to a higher altitude (diesel is TURBO after all)
versus losing HP the moment you leave the ground (or the moment your
density altitude goes up)

On a 100dF day at any altitude, the difference would likely be in favor
of the thielert (especially with CS prop)
