Im trying to make a max speed imperial eagle for fun, but I think im stuck now. Whatever I do I cant get the speed above 837ms. It gets to a stage where reducing weight dosnt matter anymore. I see other players have gotten imperial eagles above 837, so im not sure what to do next. Im thinking it must be some secondary effect on the dirty drives roll on the enhanced drives? But which one? We have minimum, optimal and maximum multiplier. First maximum multiplier must be maxed out I guess, and then which one is the next important multiplier to look at? Its kind of confusing, any easy rule of thumb to remember so I can understand it?
This is how my multipliers look now:
