empty is 3050, max load is 4272 for a standard A8, it also lists the HP as 1700.
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.
