Thrust offered by RD-93 MA along with further composites is also not enough to achieve mach 2.0. Air frame design(specially wings) & TW ratio is the problem not DSI. Same DSI will not cause any problems for J-20 or J-31 in achieving max speeds around Mach 2.2.
Anyone tell me, what is dual rack? what is the advantages of dual rack on JF17, if its installed on it ?
Must share please if you may find. What I can take is that the air frame design of JF-17 is the main problem in achieving higher mach numbers. For it's designed for simplicity & controlability instead of speed & maneuverability.It can reach Mach 2, but it does not mean it will perform well at those speeds, DSI inherently rapidly loses efficiency at speeds approaching mach 2. In theory DSI like configurations can reach above and beyond this value, but only if they are specifically designed for that speed, the trade-off then is that their configuration is then less efficient for lower speeds. Do what you will with the JF-17, increase the TW ratio, thrust, DSI in it's current configuration will stop you from getting to mach 2 without having some undesired effects.
Only more complex, variable geometry designs will work for those speeds, which loses the whole point of DSI. Actually, there was a nice study somewhere I had about this issue, conducted by our very own Pakistani Engineers, I'll see if I can find it.

What if you are chasing the enemy and they are running away in faster planes ... then what
@Oscar
any news about dual seat variant of JF-17
