I'll try this too, just out of curiosity. I will report back if the copy process leads to any problems.

Make sure to rename every repaint in the copied folder, as said. FSX otherwise reminds you on every single paint that another one with the same name is present.
Maybe amend "Super" to every one or so.
As far as I can see, the simple copy process of the original 727-100 folder, the renaming of this folder and then the renaming of every livery entry in the aircraft.cfg gives you another complete model to play with.  :)


Seems like the modification on the "Super" wasn't that big.

Quoting Monteycarlos (Thread starter): Firstly, what is the freight capacity like in tonnage and in terms of containers available? Firstly, the Super27 is the tag word for the Valsan engine mod which replaced the pod engines, #1 and #3, with JT8D-217 or -219 engines. The gross weight depends on the aircraft that was modified. You can have both 727-100's and -200's modified to the Super27. The freight weight is usually the standard 40,000 lbs for the -100 and 60,000 lbs for the -200.

So more thrust seems to be the main difference here. I've already altered the thrust values on the normal 727 as I found them to be too low when compared to some Wikipedia data and especially when trying to get a loaded 727-200 out of higher situated airports.

So the Super has two JT8D-219 with Maximum thrust: 21,700lbf / 96.5kN (JT8D-219) while the No.2 engine stays the same as on the normal -100.
FSX doesn't support different engine types I think, so just take the average value of this 1 old, 2 new configuration and edit the static_thrust=xxxxx value at [TurbineEngineData].
This should give you a nice boost of performance.

Don't ask me how to establish the better efficiency of the two newer engines when editing the fuel consumption though. I have no idea how to get correct values there, this would take some try and error attempts with some charts being available. Have fun.  :)
