2 ways of looking at it 1) the power 2) the speed.
the power, not an issue really, there are vipers available from aftermarket companies that run 1800hp and remain street leagle. vectors original w8 twin turbo's ran up to 650hp, and avtech used the wx3 design and tested a vector motor with 1100hp, said it functioned extreamly well. gerald will find a way to make the power. his limit will be getting that 1800hp and emense torque to the ground while not ripping the trans apart.
2) the 275mph top speed. based on the design shown, likely not. to much aero and it produces lift, which at certain speeds will lift the car off the ground. technology then allows for different ways of making downforce, however 90% of the time it takes away from the aero, therefor liiteing it's performance
