Why still no dive acceleration difference?

how you want to interpret that is up to you.

See my edited post. Fw190A8 is Notleistung emergency boost system which produce 1953HP, I use 1980HP in calculation. There is some exhaust boost(bigger than 27HP at high speed). 578km/h, I use 580km/h.

So fw190a8 drag coefficient is no less than 0.2790

Ok, let's be more accurate with 4272kg

when dive in 45 degree, let the new equilirium speed as V:

new engine thrust should be 7231*(161/V)

m*g* sin(45)+t=d*V^2

4272*9.8*0.707+7231*(161/V)=0.2790*V^2

thus

v^3-106090V-4172728=0

Finally, we get V=344m/s=1238km/h. roughly euqal to 1232.6km of 6-ton P47D.

1)There should be 100HP+ exhaust boost for fw190A8@580km/h@SL, so darg efficienct should be more than 0.2790.

2) max load is 4272kg for a standard A8, max load is 8000kg for a standard P47D, even with 7-ton weight, P47D could also has higher equilirium speed.
