Torque is scaleable...HP isn't. F2D is combat and while the high end engines are extremely powerful they're not in the same class as F2A (which are the engines I'm talking about). An "over the counter" F2A engine (like an Irvine 15R or Profi) will produce around 2HP at 40K and scaled up this would mean an F1 pylon engine making 5.3HP.

Not impossible.
