I think this thread is enough.
Really cool game, btw!
I’d sugest to use the search function 
Currently, as discussed above, the game has 80s turbo tech, but the devs plan to re-design the engine designer
And after that, further in the development of the game, they’ll do a forced induction revamp, where they plan to add modern technology, such as superchargers and different types of turbochargers.
