How to make a Time Warp system like in KSP

Hello everyone, first time i’m asking a question here.
I hope I won’t do it wrong so here my question :
I want to make a Time Warp like in Kerbal Space Program, but Time.timeScale is limited by x100 the usual speed. Is there a better way to do it?

Leave the TimeScale to 1 and use variables to define custom TimeScales for objects.

public class CustomTimeScale 
{
	public static float timeScale = 9000f;
}

Then you can do something like this:

void Update () {
    transform.Translate(Vector3.forward * Time.deltaTime * Time.timeScale * CustomTimeScale.timeScale);
}
