Two things can limit your top speed with that combination:
- too short runway ie time to reach the top speed
- too low / slow gearing

If you want to drive the car for longer time and not only go for top speed then you have to compromise. Usually the limiting factor is that too fast gearing will overheat the motor. That's why there's the calculated 40mph speed rule of thumb. You will use gearing that will get up max 40-45mph but overall this is the maximum you will get out of the combination over longer time.

If you "overgear" your car to do speedruns for maximum top speed, you'd still have to take care not to overheat anything!

Basically the faster the gearing = the more power you get = the higher top speed .... until you overheat the engine, burn the ESC, melt the plugs off the wires or kill the battery ;)
