Faster as in top speed. I very much doubt it will be doing over 260mph like the Chiron can. That's just down to pure power where the Bugatti has c.400bhp more than the Valkyrie.
Agree on that obviously

As for acceleration, it'll be interesting to see whether it can match / beat the Chiron's current records. The Chiron's 4wd means it has ridiculous acceleration thanks to its traction advantage.
It´d be an interesting comparison, I´ve always wondered how much lighter a 2wd car must be to match a 4wd car in acceleration, it´s comparing apples to oranges but fun anycase

I'd be interested to know the real situation with the loads / tyres. I've seen suggestions that the Bugatti produces half a tonne of downforce. Add that to its weight and you have loads of 2.5t on the tyres. Tyres that can take that and do a speed of 260mph ought to be good enough for the Valkyrie to produce much more downforce given its much lower kerb weight. As always, getting real figures is very difficult for we in the general public.
No necessarily. Problem with tires is not the vertical load at max speed, wich in both cars must be around 3 tonnes as the Bugatti higher weight will compensate the lower DF (more or less).
Problem comes when, at that max speed, with around 750kg on each wheel, you turn the wheel and the weight transfer increase the load in the outer tires. That increase will depend on the DF produced by the car, higher DF, higher load will be transfered to the outer tires, so the Valkirie will load those tires significantly more than any Bugatti.
Moreover, appart from the vertical loads, there will also be some huge lateral forces into those tires wich will directly depend on the DF and max lateral Gs, so also here the Valkirie will stress the tires much more than any Bugatti.
My wild guess is these lateral forces are the limiting factor, no road legal tire is designed to support any significant lateral force (> 1G), even if they can take the necessry weight/vertical force
