* Gear ratios: Different gear ratios will affect the top speed achievable.
* Tire size: Larger tires can slightly reduce top speed.
* Modifications: Performance modifications like engine tuning, exhaust systems, and cold air intakes can increase or decrease top speed.
* Aerodynamics: Even small changes to the car's aerodynamics (e.g., a spoiler) can have an impact.
* Road conditions and external factors: Wind resistance, incline, and even air density play a role.
While a stock 2002 Mustang GT might *theoretically* reach speeds around 130-140 mph, this is under ideal conditions and without exceeding the car's safety limits. Reaching this speed is not recommended due to safety concerns. Many factors beyond just the engine's capabilities are at play at these higher speeds. The car's handling and braking may become compromised, and the risk of an accident increases significantly.
