How fast would the Thrust SCC go with GE-9x's?

Has anyone ever wondered how fast the Thrust SCC would go with two of the most powerful turbofans? Well first we would have to take everything about the original into account.

Original Engines: Two Rolls Royce Spey 205 (50000 lb of thrust total)
Original Weight: 23369 LB
Original Max Speed: 763 mph
Original Engine Weight: 8186 lb total
Original Thrust/Weight: 2.13

Now we will replace the engine weight and lbs of thrust with the GE-9x's ones.

GE-9x Weight: (about 80,000 total)
GE-9x Thrust: (about 268,200 lbs of thrust)

We will re-calculate the total weight and we will have 95,183 lbs!

The new thrust to weight ratio will be 2.82.

So if you decided to trap two GE-9x's to your Thrust SCC, you should expect it to go around 1007 mph, 244 mph faster than the original!

    It’d probably flip about because of the large diameter of the GE9X with the amount of thrust it makes, and the light weight of the craft. And I’m not sure the GE9X would behave well going super sonic.
    Also it’d probably suck up the entire earth... Lol jk but there would be a lot of dust damaging the engine.

    @232287168147825 yes. it was just an experiment to see how fast it might go with about 260,000 lb of thrust

    The cool part about engines is that their thrust varies on the airspeed (a turbofan generates more thrust at high speeds than a high-bypass fan, which is more efficient at low speeds)

    The thrust SSC uses turbojets to go fast, rather than high-bypass fans.

    If you really want to go fast, you can use ramjets or scramjets, which start working well at extremely high speeds
