The F-15E is powered by two Pratt & Whitney F100-PW-220 or 229 engines that incorporate advanced digital technology for improved performance. For example, with a digital electronic engine control system, F-15E pilots can accelerate from idle power to maximum afterburner in less than four seconds, a 40 percent improvement over the previous engine control system. Faster engine acceleration means quicker takeoffs and crisper response while maneuvering. The F100-PW-220 engines can produce 50,000 pounds of thrust (25,000 each) and the F100-PW-229 engines 58,000 pounds of thrust (29,000 each).
50000 libras ~~ 21600kg
58000 libras ~~ 25056kg

Weights
Without CFT With CFT
Operating 14,650 kg 16,550 kg
Basic Mission Takeoff 21,700 kg 27,900 kg
Basic Mission Landing 15,250 kg 17,150 kg
Maximum Limit 34,850 kg 36,750 kg
TWR do F-15E com as F100-PW-229 = 1,514~1,71 (com e sem CFT)
Agora do Raptor, SUPONDO-SE que o peso vazio seja de 18 toneladas:
30240kg de empuxo dá um TWR de 1,68.
(Se o peso do Raptor vazio for abaixo de 15 toneladas aí virou covardia
)Então comparemos com o F-15C.

Thrust: (C/D models) 23,450 pounds each engine
20260,8kg de empuxo dá um TWR de aproximadamente 1,4 com o avião VAZIO.
