just go into the
data\equipment\engine_equip.ini and change the values....
[Engine
nickname = ge_bf_engine_01
ids_name = 263690
ids_info = 264690
volume = 0.000000
mass = 10
max_force = 48000 <--------- change this number to anything ya want
linear_drag = 599
power_usage = 0
reverse_fraction = 0.200000
flame_effect = gf_br_smallengine01_fire
trail_effect = gf_br_smallengine01_trail

cruise_charge_time = 5
cruise_power_usage = 20
character_start_sound = engine_br_fighter_start

rumble_sound = rumble_fighter
rumble_atten_range = -5, 0
rumble_pitch_range = -25, 25
engine_kill_sound = engine_br_fighter_kill
cruise_start_sound = engine_br_cruise_start

cruise_disrupt_sound = cruise_disrupt
cruise_backfire_sound = cruise_backfire
indestructible = false
outside_cone_attenuation = -3
inside_sound_cone = 60
outside_sound_cone = 180
that number represents the total speed your ship goes; 48000 is 80 on your speedometer thing....if i am not mistaken 80000 is 113
also to make ships go REALLY fast just edit the constants.ini and add this line
