Because the sheet by Semper did not show the engine output, i took on the task to make nice calculations on them to get some data on them.
Engines are splitted in two groups : from 1 to 5 and from 6 to 10. The Klingon statistics have already been completed, and i'm working on the Romulans right now.
For Klingon engine range 1 to 5 i found the following formula:
R*(6.17818*10^-9*M^4-2.085*10^-5*M^3+0.02566537*M^2-13.164414*M+2741.939029)=output
R is the skill of the engineering officer (lvl1 =1.000, lvl3 =1.500, lvl4 =1.572, lvl5= 1.715, lvl6= 2.000)
M is the engine mass.
For Klingon engine range 6 to 10 the following formula:
R*(-3.91*10^-11*M^4+3.1637*10^-7*M^3-8.8532*10^-4*M^2+1.3972209*M-126.66137)=output
