The A9 did have the TS engine, the F-engine however never enter service, it was a 30mm longer version of the A8 (The current A8 airframe can be reused, maybe with the exception of the canopy that was the same as the F8)
The A-9 used both the new wood paddle propeller, and the metal propeller.
The TS engine had 1,471 kW instead of the BMW 801 D-2 that had 1,250 kW the A7-A8 had.
The BMW F-1-engine had 1,765 kW.

The 190 A-9 didn't have an engine any stronger than the A-8. The myth of the A-9 having a more powerful engine never really materialized.
