French WW2 Engines

[Bretoal2]

HS.12ydrs is the same as HS.12Ycrs
Only difference is that Ycrs has motor cannon

HS.12ydrs1 and HS.12Ycrs1 are different to what B.135 has

That's what I said in post #5.

But obviously the B-135 engine had different ratings (Was it an Avia-built Hispano ?) , with over-boost manifold pressure settings at 920 mm Hg. The 920 mm Hg figure was used in 12Y 21 and 12Y 29, that were slightly more powerful than 12Ycrs owing to their CR of 7.

Ok so if I've got this right…

775CV at SL (880mmHg)
810-815CV at SL (920mmHg)
850CV at SL (960mmHg)
-
860CV at 3300m (880mmHg)

I calculated these speeds for B.135

455km/h at SL (880mmHg)
520km/h at 4000m (880mmHg)
-
462km/h at SL (920mmHg)
527km/h at 4000m (920mmHg)
-
469km/h at SL (960mmHg)
534km/h at 4000m (960mmHg)

The known tables for HS-12Y only go up to -50/51 and GR-14N go up to 48/49. I've seen claims of 12Y-54/55 in Cuny and Danel.

Do you have any info on the maximum variant indexes planned for both engines before the Fall of France and their features?
