The Super 27 is the same as the standard 727-100. All of the 727-100 use the same aircarft.cfg and cs727100.air files in the CS_B727-100 folder. So it makes no difference whether it is a standard, another company and RE/another company model. You do not get the extra performance.

I think you can copy that CS_B727-100 folder, tweak the aircraft.cfg there (thrust, fuel, weights, as you like) and just have to make sure that you rename the models showing up in the aircraft selection screen.
FSX and you will get mixed up otherwise.

I haven't tried this tweak but it should work.

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.

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. 

Hi. I have some numbers to work with now. But I couldnt count them all in because it was too mutch (all engine variations, winglet efficiency, hushkits, newexaust nozzles and more). So I took the very basic.
The numbers I did include was the total thrust on the standard 727 engines JT8D-7(3x14000lb) and total thrust on the super 27 JT8D-217C(1x14000lb + 2x22000lb).
The number 2 engine is the same, but 1 and 3 is more powerfull and burn the fuel more clean and efficient. So, total thrust increase is 38%, and fuel decrease is around 20%.
So the thrust scalar should be from 1,0 standard to 1,38 S27. And down the fuel flow scalar, from 1,0 standard to 0.8 S27.

It seems to work fine in my FSX. The climb capability was alot better. I have only done this with the 100 series (SITM). 200 series is to be tweaked soon.

The numbers I have not included is the total payload increase. The 100 series it was up to 6000lb (MTOW from 170.000lb to 176.000lb) and the 200 series it was up to 10.000lb (MTOW from 210.000lb to 220.000lb). I'm not sure how to work this out, so if any of you have any ideas it's very welcome. Also if anyone disagree in the numbers I presented here please let me know.

Thanks

You got a big point there, but I have to ad that I am no math-expert. So I agree it seems a little overkill, but still, the numbers is pure engine power increase. I haven't included the MTOW, CG and all of the rest. Please help me out.
Energy transfer versus mass... I have no idea on how to even begin.
I have the numbers, I just need to put them in some kind of....ehm...mathematic formula, or whatever it's called.

Anyone good with numbers? Please give it a go.. "I have so much to think of, but so little to think with"

At least I tried. I'm going to down it a little on the engine power so it's ruffly 16-18% more than the standard, and down the FC about 10%. At least there is a little difference now.

Thanks for the interest and input guys. I really appreciate it.

Working on a -200 series version.
