It seems to be more complex than I have expected.
I tested all combinations between old and new .cfg and .air files with full cargo (30000 lbs) and 100% fuel in all tanks.
With Climbing rate at 1500 ft/min climbing speed reached at 145 kts in all combinations.
Cruising speed at 10000 ft reached to 200 kts.
But I think there are influences at climbing phase if you are using pitch from autopilot panel or trim.
Using pitch it is possible to run in stall.
Another observation I found that .cfg-file will be changed after each flight. (seen at change of date/time of the file)

If you use the ACE, and then SAVE any changes, that will change the aircraft.cfg, therefore changing the creation date. Make no changes, and the date won't change. Wink

Hey all,
I think I found the reason.
At the ground you can lift the ski by punsh the air deflector button.
But after T/O the ski works like an air deflector and reduce the speed.
After punching air deflector again the climb speed at 2000 ft/min raise to 220 kts !! This effect is not visible. It seems to be inside of the C130.air-file.
I am happy about this observation.

If you look at the aircraft.cfg file you might find why you don't see any difference between the variants.   They all have the same settings no matter E, H, J (KC,HC,LC,AC)

[TurbineEngineData]
fuel_flow_gain=0.02
inlet_area=1.0
rated_N2_rpm=29920
static_thrust=158
afterburner_available=0
reverser_available=1

[turboprop_engine]
power_scalar=1.0
maximum_torque=19600     ;H:maximum_torque(23030)

Not really sure how they came about these configurations for the maximum torque but all the C-130 legacy (E,H) models should have the Allison T56-A-15 engines, and the J has the Rolls Royce AE2100-D3

When you compare the older T56 models with shaft horse power you can see the difference.
T56-A-7: 4,200 shp (3,133 kW)
T56-A-14: 4,600 shp (3,433 kW)
T56-A-15: 4,591 shp (3,425 kW)
T56-A-425: 4,600 shp (3,433 kW)
T56-A-427: 5,250 shp (3,920 kW)
T56-A-427A: 5,100 shp (3,806 kW)

The 2100D3:
Power:
AE 2100 A/P: 4,152 shp (3,096 kW)
AE 2100D2 and AE 2100D3: 4,637 shp (3,458 kW)
AE 2100J: 4,591 shp (3,423 kW)

In regards to what you are seeing on climb out the difference in settings may be a place you look at (19600 vs 23030) on the maximum torque.
