I have no idea if this has been suggested yet and i am to lazy to read through 700 pages of content suggestions but could you do something like AngeTheGreat and simulate the actual engine with airflow, pistons camshaft, crankshaft etc.? It would be great to see a system like that in an actual game that focuses on vehicle simulation. I of course understand, if such thing is not possible and i apologize if someone has already suggested this feature. P.S He has some great videos about his engine simulator that you should check out like this one --- Post updated --- also his most recent video explains how his fluid simulation works:
People talked about it here quite a bit https://www.beamng.com/threads/engine-simulator-by-ange-yaghi.87487/
