I think Dominator can reach around 180 speed with Unstable injector + SO and Coordinated movement + fighter uplink + Helmsmanship. Activate Burn Drive and it can be as fast as interceptors. Not sure how practical it is but still, you can make your giant brick out speed sport cars.
Just so you know, percentage bonuses are normally added together, and not multiplied, with flat bonuses added in at the end after percentage ones. Percentage penalties generally multiply however. Essentially, positives get put together in the worst way for the ship, and penalties also get put together in the worst way for the ship generally. There are a few exception though, but none associated with speed as far as I know.
You can try out an Unstable Injector + SO, along with a full +20% Coordinated manuevers + Elite Helmsmanship + 100% CR + the 0-flux speed boost, and a basic Dominator caps out at 132 speed (on the display). Burn Drive does bump that up to 332 in a straight line, which is Talon tier speed. The shields being down during it, and no turning, means you can't prevent chip damage, and faster ships with a maneuverability system typically will move out of the way.
Most of that is coming from the 0-flux boost to be honest, and an identical Dominator without SO can hit 112 while it's flux is zero.
The fundamental problem with that is the Dominator's range shrinks to 450 which is less than frigate tier weapon range, and is on average slower than most frigates. Assuming the other side also has an officer in a frigate with Helmsmanship and has Coordinated Manuevers, even a slow Lasher is hitting speed 156, potentially with range 800 ballistics. Not saying SO Dominators are necessarily bad, but they are still not going after frigates and fast destroyers very well, and need to still be escorted by faster ships or have local fighter superiority. The AI has issues with being out ranged and out sped.
Also, in case it was unclear due to it's description, Fighter Uplink affects only fighters, not ships.
