New Engine System

This Idea sparked when i was playing with carrier battles (somewhere in 1.2 i think). It went into one of my unreleased versions of Starmasters mod. I use the common system that most mods use(thrust > mass). However the fun part went in to the drive reactor... every ship size had its own (restricted by mounts). With larger ships gaining the larger bonus.

The effect was all ships moving at the same speed like in Startrek. Although you can increase the speed of ships. the smaller ones getting the best advantage.

Im putting this system into my SEV version of Starmasters. Without the dam 100+ drive reactors. To do this my locking the editor when you place the drive reactor on it. This is because the reactor is doing to give bonus movement based of engine amount and ship size.
However i had one problem in SEIV... Nothing was organizing a set speed for an empire. what i am trying to say is, in startrek most ships move at warp 6 but some ships can move warp 8, with this system you just add more engines (a fixed amount) and you get faster. What i want is an "effective" point. Were if you put the right amount of engines the ship is good. However when taking engines off takes, your speed has a LARGE drop. Also when going over the "effective" point you slowly loses you drive reactors advantage.

The way i am hoping to have this happen is by giving all engines three values.
- min thrust
- effective thrust
- max thrust

- min thrust
This is the normal value you get from engines however its toned down so even the smallest ship with need several to move even one sector

- effective thrust
This is a value that will be used my the drive reactor. This number will be higher then the min thrust however the lower the number the less engines you need to be effective. To know how many engines you need use this formula...

A/((A/B)/C)

where:
A- is the size of the ship
B- is the min thrust of the engine
C- is the effective thrust

So for a 250 tonne ship to have effective movement with a min 10, eff 15 engine it would need.
250 / 10 = 25 to move one space
250 / (( 250 / 10) / 15)
250 / ( 25 / 15 )
250 / 1.6666667
150 engines to be effective, Or 6 times the movement.

- Max thrust
This is the point were the drive reactor will not give any more bonus movement. No, it sill gives bonus however adding more engines will only give its min movement to the ship. This "Afterburn" is ineffective.
Same as the effective movement the formula is
A/((A/B)/C)
where C is the max thrust stat.
so in the same example, if the engine had a max thrust of 20 then

250 / (( 250 / 10) / 20)
250 / ( 25 / 20 )
250 / 1.25
200 engines to be Maxed, Or 8 times the movement.

If the base speed of an empire was 12 then when effective the drive reactor would be giving out 6 bonus movement. If the max was 15 then the drive reactors bonus would be 7. After the max for the drive reactor has been reached it will only give out that amount. ie 7 bonus. to be faster this ship would need 25 more engines per movement.

For a larger ship (500) with the same other variables.

600 / 10 = 60 to move once
600 /(( 600 / 10 )/ 15) = 150 to be effective
600 /(( 600 / 10 )/ 20) = 200 to be arrrhh(some numbers), well i thought i had it wrong

Tell me what you guys think.
p.s. no you do not need 200 engines this were some quick calcs sorry. however i had a solid theory. ill re do the formula at home were i have them printed out.
