Actually, you can also get 3 base movement by using Quantum engines. I had thought it was actually possible with J.P. engines, but no.

At any rate, it is reasonable to expect a sooner increase in speed with research into standard propulsion tech, and expense. The problem is that SE4 only supports integral speeds, so a 50% increase is the least possible above speed 2 (from 2 to 3). I think I'll add just enough to the max engines value that will make J.P. engines give speed 3, and Q engines speed 4, while ion and C.T. engines are stuck at 2 (if such a number exists). I'll fiddle with it. I might also add a "faster colony ships" specialized tech, not terribly expensive, that gives colony ship hulls that can mount more engines.
