It is third tutorial (this is second:https://beamng.com/threads/how-to-make-your-own-transaxle-based-on-another-mod.61166/) and today we will create your own turbo based on another mod. In the first tutorial I described in detail where the files are and how to open them. We need "turbo" file (but the turbines are most often located in "engine"). Next, I will describe in detail all the parameters of the turbo: 1) wastegateStart (red arrow) - start pressure (PSI) 2) wastegateLimit (yellow arrow) - end pressure (PSI) 3) maxExhaustPower (blue arrow) - exhaust performance 4) pressureRatePSI (black arrow) - max pressure (PSI) 5) damageThresholdTemperature (green arrow) - the temperature at which the turbine is damaged. Next we will see 2 columns (first is turbine RPM (red arrow), second is pressure ((blue arrow)PSI)) Below we will see 3 columns (first is engine RPM (yellow arrow), second is turbo's effiency (blue arrow), third is exhaust factor (red arrow)). If you do not understand something do not hesitate to write me in private messages (can be in Russian), I will try to answer all questions (and not only). Will soon release a tutorial for the tanks.
Even though I don't know how to do this myself, I'm not sure if you are exactly 'qualified' to make these tutorials. I mean I think it's great you're trying to help the community, but I think it would be a better if it was made by someone with more experience. I'm not exactly sure how credible this tutorial is considering you spell columns like: I'm not trying to deter you from modding or helping others out in any way, but I think it would be better if you got more modding experience first
Your dedication to making this tutorials is admirable, but they aren't very helpful and rather inaccurate, and seem to be based on a very outdated version of the game. For example, "pressureRatePSI" is not the max pressure of a turbo, and your descriptions of the boost curve table isn't very helpful. For anyone who wishes to see how turbos work, I would suggest looking at the turbo wiki, here
