Ender 3 pro max speed

i have a ender 3 pro that is un modified, and recently i decided to amp up the print speed to a rediculous 700%. (probably not the smartest)

however i was pleasently suprised that it did work just fine. the print quality was not the best, but it ran that fast and completed the print in about 5 hours. later i calculated the print speed to be around 270mm/s

i have heard that ender 3s can only run up ot a certain speed, because of the firmware, but this seemed to prove them wrong.

i also have a sprite extruder, and cr touch. the firmware im using is just stock creality for the sprite extruder and cr touch.
