Procedural piston engine
We need a new procedural engine, with a torque curve and a proper sound, that can link to propellers or to a gearbox which can be linked to wheels.
This engine should have a changeable number of cylinders, displacement and configuration (ie, radial, flat, V, inline) and also have options like air or liquid cooled, carburettor or injectors, petrol, avgas or diesel etc.
The quality of engines in the base game is truely miserable at the moment, to the point that they don't even spin at their indicated RPM or make the right tone noise. The advantage of SP over SR2 is it is much more intuitive to make older things, and I think a procedural piston engine will suit the game well.

This is a great idea, limitless possibilities. I'm not sure how Automation does the engine sounds, but a similar audio setup would be amazing, with various noises for V12s and radials. Propeller torque would also be a great optional thing.

This is one of the best ideas I’ve seen in a long time and could definitely be added to the game
