Hey so I love boron ships they are amazing but one weakness I seen with them is acceleration...
I just brought myself a boron Ray it has nice top speeds but by the time it even gets near top speed I've already got to the end of the sector... it takes forever to reach top speeds.... same with large freighters...
So my question is what mods (In game mods not nexus mors ect) do I need to install on my boron ships to make them reach top travel speeds faster?
You're looking for mods that reduce "Travel Attack Time" as that is what determines how quickly the engines accelerate in travel drive. TER drives are well-known for having extremely good attack times, shifting into maximum speed the quickest and consequently being more nimble despite its lower maximum top speed. The BOR engines unfortunately are about the polar opposite, as you've discovered. The instant transition for L and XL drives are an interesting gimmick as a tradeoff, though.
The problem here is that there are only 3 mods that affect Travel Attack times, and they only go up to a 30% reduction at best, so you're still looking at over 2 minutes to reach top speed.
The purple Vikas mod can grant a 10-30% reduction in Attack Time, while the blue Mira and green Spur mods only grant a 5-20% reduction.
Chassis mods reducing Drag will improve overall top speeds, but won't affect total Travel Attack time, I believe. I'm not sure if Mass reduction improves travel acceleration, or if it only affects basic acceleration, though.
