Title: boost pressures used by the Fw190D-9
Post by: MiloMorai on May 02, 2018, 07:45:54 AM

Could someone be so kind and tell me what manifold boost pressures the Jumo213 used?

The manual says maximum of ATA 1.55 at 2,700rpm (max). The gauge reaches to 2.5, but the engine will never get there. You can also run up to 3,300rpm, but not at ATA 1.55.

The latest digital copy of a Jumo book that I have found is for the 211.

Thanks Chalenge.

I have a recollection of 2.?? but this was for the 2000hp+ motors???

I don't see any evidence of that, not that it didn't just I don't have any manual that says so. Lyric is out of pocket at the moment, but he is better at finding things like that.

Thanks all for your input.

The reason was asking came across a photo of a boost pressure gauge that went to 2.00ata.

Am I reading that ED graph correctly? Shows a boost of almost 2.0ata.

It does show that. I doubt very much that it was capable of that in combat aircraft. Limited resources and all you would never push your planes that hard. Just recall the ME109 racing done with one-time engines.

Pretty much what Yak-3 does with endless WEP in AH, and IRL had overheating problems.
