Ok, so I have been testing the warp drives on different tiers. The example I use is a simple Exploration ship with only the essential components and 4 fuel cells.
Here are the numbers for the different techtiers (Note: I presume one techtier to be fully researched in order to get this number. Example: On Tier 4 you get access to Ultradense fuel cells, the two different specialized reactors and the three different Warpdrives):
Range measured in sectors:
T4 with Quantum Reactor: Highspeed Drive: 7,27; Fastjump Drive: 6,94; Efficient Drive: 10,87
T4 with Fusion Reactor: Highspeed Drive: 8,81; Fastjump Drive: 8,42; Efficient Drive: 13,18
T5 QR: HSD: 7,91; FJD: 6,84; EFD: 11,08
T5 FR: HSD: 9,64; FJD: 8,34; EFD: 13,50
T6 QR: HSD: 10,30; FJD: 9,09; EFD: 13,97
T6 FR: HSD: 12,62; FJD: 11,14; EFD: 17,13
T7 QR: Torrent Drive: 14,09
T7 FR: TD: 17,89
T8 Quantumfoam Reactor: TD: 17,47
T8 Hyperfusion Reactor: TD: 22,57
T9 QFR: TD: 19,48
T9 HFR: TD: 25,16
Since I had to increase the fuel consumption of the first 4 tiers of reactors considerably to get these results, pre- Warp Field Precursor shiprange got considerably cut down.
PS: I have finished one version with the numbers shown above for the mod Extended Universe if anyone is interested. I`ll talk to Haree78 first though to get his okay, since the research.txt and components.txt contains his work too in order to function properly together.
