34 seconds with my Kerrari GTO. A picture of my ship: A deafault Kerrari GTO sip does 1:34 on 100km. That\'s because the fuel thank has a mass of 7. The fuel think I used had only a mass of 0,9. The default ship can only use 50% of it\'s power because when it\'s over 50% the kerrari falls of the ship. Now going 200 km/s, 8:34 after lunch, with still 1/3th of it\'s fuel.
