What is Torque F.I. or Power F.I.

Hi,

what are the Power F.I. or the Torque F.I. lines in the first diagram in the upper left corner?
What is F.I.?



My only idea is, that this F.I. curves belong to the motor characteristic line with TURBO or COMPRESSOR support.
But then, why are the normal (not turbo supported) characteristic lines also there?

 

I'm pretty sure it stands for "Forced Induction". You are right.

They make a good comparison point to see where the Turbo is actually kicking in. Helpful for tuning.

 

blue and yellow are torque and power without turbo respectively.

 

I am surprised that someone didn't got it........ But yeah, it means forced induction, TECHNICALLY it should mean the power you get when using a turbo, NO2, Supercharger, or more than one, but the game doesn't has NO2 support and the supercharger doesn't technically count as forced induction in the game
