Strange that a 80 N turbine can produce 130 N running a fan. Considering the losses and running two turbine wheels and then some planetary gearbox or the like for the fan takeoff. Yet you are somehow able to almost double the original turbine core output.

I am assuming the TF-200 would have something to do with the inlet diameter, then if that is that case to get 130 N you would need around ~ 10K W of power to the fan just off the top of my head.

Pretty sure your going to get a lot less than that from a 66 core.
