Aerodynamics of the car, the size of the wheels, the weight of the car, and the size of the CO2 cartridge.
It will cause it to hidroplain
Yes, if you're using the co2 car on Earth. All of Newton's laws will affect every moving object on Earth, and your co2 car is no exception.
No.
The AC condenser would effect the performance of the AC system in the car.
It makes it fly
Normally yes because the replica's value is less than the original, but factors such as performance may also affect the cost. To be sure, contact an agent with vehicle specifics.
It can effect engine performance and fuel burning efficiency.
Yes, a bad cat can cause issues.
surface friction and sliding friction
Yes. Some of the vehicle's electronics are voltage sensitive.
Aerodynamics, weight of the car, horsepower of the engine, are all factors in the speed the car can travel.
