Hi Bill!
You can find the details on my site:
http://kurfurst.org/
You can find the relevant engine output (in all cases, static power) here:
http://kurfurst.org/#engines
The tests themselves note the power regimes, so its a matter of putting 2 and 2 together.
But a quick recap - I am not sure what G types are you interested in, or is it cruise/max power, SL or rated alt?
Anyway, here it is:
G-2 (605A) - Mtt. calculation/official figures for early type:
max. 537 kph @ SL, 660 kph @ 7000m. 1310/1250 PS (static)*
max cruise. 600 kph @ 6000m, 1090 PS (rammed), 225 gram/PS/h fuel consumption
G-6 (605A) - flight trials:
510 kph @ SL, 625-630 kph @ 6700m. 1310/1250 PS (static)*
530 kph @ SL, 640 kph @ 6700m. 1475/1310 PS (static)
max. cruise. 480 kph @ SL, 585 kph at rated alt (ca 6 km), 1075 / 1080 PS
G-14/U4 (605AM w. MW boost)
568 kph @ SL, 665 kph @ 5000m. 1740/1700 PS (dynamic), datasheet, impossible to make out wheter calculation or test flight
max. cruise. 468 kph @ SL, 590 kph at rated alt (6 km), 1000 / 1080 PS (dynamic)
G-5/AS G-6/AS (605AS) - flight trials at 30 min rating:
507 kph @ SL, 654 kph @ 8300m. 1275/1150 PS (static)*
* at 30 min ratings
G-6/AS (605ASM w. MW boost)
560 kph @ SL, 675 kph @ 7500m. 1800/1500 PS (static), test flight
560 kph @ SL, 690 kph @ 6800m. 1800/1500 PS (static), another test flight
max. cruise. 480 kph @ SL, 610 kph at rated alt (8,4 km), 1030 / 1050 PS
G-14/AS (605ASM w. MW boost)
560 kph @ SL, 680 kph @ 7500m. 1740/1495 PS (dynamic), datasheet, impossible to make out wheter calculation or test flight
max. cruise. 460 kph @ SL, 620 kph at rated alt (8,4 km), 1000 / 1040 PS (dynamic)
G-10/U4 (early 605DM w. MW boost)
560 kph @ SL, 690 kph @ 7500m. 1750/1570 PS (dynamic), datasheet, calculation from August? 1944
max. cruise. 465 kph @ SL, 628 kph at rated alt (8,4 km), 1020 / 1030 PS (dynamic)
K-4 (early 605DM w. MW boost)
580 kph @ SL, 710 kph @ 7500m. 1750/1565 PS (dynamic), datasheet, possibly calculation from August 1944
max. cruise. 477 kph @ SL, 645 kph at rated alt (8,4 km), 1020 / 1030 PS (dynamic)
K-4 (605DB and DC w. MW boost)
DB : 595 kph @ SL, 710 kph @ 7500m. 1850/1600 PS (static), calculation from January 1945
DC : 607 kph @ SL, 710 kph @ 6000m, 710 kph @ 7500m.. 2000/1800/ca. 1600 PS (static), calculation from January 1945
max. cruise. probably the same or a bit better (DB/DC max. cruise power 1100/1140 PS).
Hope this helps.
