The Q-Charger provides a boost in speed when at maximum throttle at the cost of some fuel and energy. This OXP authored by CommonSenseOTB July 25, 2011.


Q-RaceTech is proud to present an innovation in Main Drive boosting technology. The Q-Charger uses new understanding of the principles governing Main Drives and Quirium Fuel to boost the top speed of any ship by 2x. The Q-Charger kicks in when the throttle is set over 95% maximum. The speed will be maintained at a steady 2x ship max speed until it is kicked off by lowering the throttle below 95% maximum. The Q-Charger requires fuel injection be installed before buying and requires both fuel injection and either an extra energy unit or a naval energy unit for operation. The Q-Charger will automatically cut out when either fuel drops below 0.1 ly or energy drops below 32.

WARNING: Serious damage may result to the Q-Charger if either the fuel injection or energy unit is damaged while in operation. Additionally, the Q-Charger is particularily vulnerable when it is damaged directly. Proper safeguards prevent main drive damage however. It uses 0.1 ly of Quirium fuel per 30 seconds of use and 4 units of energy per second.

Remember, things go better with Q.

You can disable Q-Charger by priming (Shift+N) and activating (n) if you want save your fuel sometimes.

Small ships under 30t mass like an Adder can not equip it due to the space requirement.
