SD-10 Dual rack drag

[Creampie]

I noticed some really bad drag issues with the JF17 top end speed quite some time back and never really got around to testing it. Never really needed to test it, but I don't think this is as intended. I know that the RD-93 isn't the most powerful engine & these jets don't neccasirly need to be too far above mach anyway.

Below are 4 screenshots showing the fuel, speed & loadout.

My question is, Is this amount of drag intentional? If so, Why? 

It doesn't seem to make much sense that you lose 33% of your top end speed by adding the additional 2 missiles & their pylons.

I've got some testing yet to do with other weapons and will post them as well when I get a little free time.

In this screenshot, With 100% fuel, we are at 35k on Syria with the temp set to 20C, Max speed of Mach 1.55, Single rack SD10 and dual PL5s

 

In this screenshot we are 51lbs of fuel, 35k feet on Syria with the temp set to 20C, Mach 1.57, Single rack SD10 and dual PL5

This difference is a little irrelevent to my concern, As we are approaching top end speed anyway, But just for testing I wanted to see.

 

In this screenshot, FULL FUEL, 35k, Syria, 20C, Dual rack SD10, Dual PL5s, Speed of Mach 1.10

 

And the last screenshot, 51lbs of fuel, Syria, 35k, 20C, Dual Rack SD10s with dual PL5s and a speed of Mach 1.15

More testing, Both of these test are something the JF17 can not do in full burner. 

Same parameters, Syria, 35k, 20c - Flight time of 222nm Mach 1.33) (0.22 mach faster than a 40nm flight)

null

Same parameters, Syria, 35k, 20C - Flight of 222nm Mach 1.11 (0.01 Mach faster than 40nm)

You can ALMOST hit mach with 2 SD10s, 2 PL5s & 2 GB-6 SFWs (0.11 slower than the subject in question....., 2x Dual rack SD10)

Same parameters, Syria, 35k, 20c (40nm trip)

Here is the biggest concern one,

2 PL5s, 2 BRM pods (the weapon with the most drag on the JF17,) 

Same parameters, Syria, 35k, 20c 40nm Speed of mach 1.01 (0.09) slower than 2 SD10 & 2 PL5s
