Drag power, Full Load Power

My team doesn’t have data for drag power or full load power in the engine tab, What can I do regarding this problem? ive looked online for this data regarding our engine but i cant find any.
Thank you

Good morning,
do you have a rough idea of the max torque and power that the ICE will produce? Is it NA or Turbo (torque curves are slightly different between the two)?
If you don’t have any data you can use as Engine Model–> Characteristics value (under the vehicle model–>tab powertrain–>Drive Source–> Engine–> General). Here you can just input the minimum and maximum engine speed and the max torque. The software will create a torque curve for you.
