ACEL with a high life value can easily get things up to FTL speeds, though it can easily malfunction if you don't use it right.
I strongly recommend that you use GPMP. it litterally makes photons teleport if strong enough.

Ah, Beatles123, but light has momentum. It can provide thrust.
It has to be a spaceship? Photons have no weight so they cant be used to speed up a spaceship.
