Your Torus Drive get an upgrade to reach the Sun faster if you buy Torus To Sun Drive for 500Cr.

Practical when an addon moved the Sun farther and if you travel to non-main stations also.

Your speed multiplier will be limited by the distance and mass of the nearest planetary object and can reach maximum 8 times of the original Torus Drive.

The built-in proximity detector will slow to 1x Torus speed when anything is arrive into scanner range. This is a help to do not miss Rock Hermits, but you still must press the slow key immediately if you want stop.

Multipliers over 2x need unpowered weapons. If you want to slow down at far objects like a Giant Space Pizza then turn back your weapons in time to avoid overrun.

By unpowering your weapons (press the underscore key) a 2x time forwarding is applied in addition so your game clock will adjusting. When you reach the maximal Torus multiplier (8x) then forwarding will be inceased to 4x so your top speed is as if you have a 32x drive. In this way you can use Realistic Stars OXP where the Sun is 8 times farther and still arrive to the Sun in 2 minutes due to the very fast last part of the travel will compensate the slow start from the planet.

Combat MFD display the multiplier if installed and is not damaged so no console messages printed in this case.

You can not leave the Sun as fast as you arrived due to the high gravity of this huge mass can help to keep up the high speed until the last moment when you fall into but will slow you strongly when you turn back to leave until you are near.

There are side effects what you must accept as feedbacks of the extreme speeds:

  • the sky will shaking,
  • the engine trails in the aft view will get left far behind you.

You can move the Sun farther in this addon also in Config/planetinfo.plist.


In Oolite v1.79 or later do not unzip the .oxz file, just move into the AddOns folder of your Oolite installation. In Oolite v1.77 make a TorusToSun.oxp subfolder in your AddOns folder and unzip the .oxz file into the newly created subfolder.
