FW190V5k/V5g BMW801? engine
 

Hello peoples!

May be simple question, but I have no answer.
In Dietmar Herman's "FW190A" book shown german paper incl. data for
V5k/V5g. BMW801 J !!! mentioned. Power settings seems strange -
1430 HP at 2450 rpm for rated altitude. The same data in Frappe/Lorant "Le Focke-Wulf 190" book. This is better then for BMW801D2 ?!
Is this not real engine data and performance for V5 were calculated ?
Could someone clear this matter ?

Thanks in advance.
Igor.
