I would imagine a motor less than 15 turns is not recommended due to the spec of the speed controller it comes with, it wont be able to handle the current (possibly melt). Saying that a 17 turn will be a lot faster than the stock motor which is probably 27 turn. But the mamba comes with its own speedo so in that respects would be fine if the drive train of the car can handle it?
I dont know the car, but im sure you would need a slipper clutch in there. Would be fun for a while though
