Racers have long known that the Imperial Eagle can boost over 900m/s with appropriate engineering but on paper the Viper Mk III, with its higher base speed (320 vs 300), could cruise faster. The two ships have the same base boost speed (400) and with its lower mass the Imperial Eagle can reach its potential much more easily. Short of being outrageously lucky under the 2.x engineering system you couldn't build a Viper light enough to attain its top speed.
With the changes to engineering in 3.0 we can choose our experimental effects and finally push the Viper's mass low enough to reach its theoretical maximum 745m/s boosting to 932ms/.
To do it we need, of course, Enhanced Performance Thrusters with fully maxed grade 5 Dirty Drive Tuning and the Drag Drives experimental effect for a maximal multiplier of 2.3296.
In order to hit that multiplier we need to get to ship's fully laden mass below the minimal mass of 61.25T.
Lightweight mods for sensors and life support will help.
A 2D power plant with the Overcharged Power Plant mod is juicy enough even with a grade 1 modification to power the ship. Higher grades are overkill and only increase the negative effects for no benefit. With the Stripped Down experimental effect the power plant is as light as we can fit.
There is finally a use for the Faster FSD Boot Sequence mod. It's the only frame shift drive mod that doesn't have a mass penalty, making it the perfect platform for the Stripped Down experimental effect which can push our drive's mass as low as it will go.
Although the Viper's cruise speed is its strength, there's no point being able to boost to 932m/s and not doing it. A 3D power distributor with the Engine Focused mod - which now goes up to grade 5 - can get close to perma boost and is light thanks once more to the Stripped Down experimental effect.
Vroom!
