When will superchargers be added to the game?
Probably after the tycoon aspect has been released and we start adding lots more engine content etc. 
I have a question regarding forced induction. Is there any chance that we’ll ever see twincharging, or is mixing the math for turbos and superchargers going to be complicated?
Also, I saw on the youtube channel probably a year or so ago a teaser for superchargers, did something go wrong with that code?
Twincharging will probably happen in a forced induction revamp which we plan on doing. It is really complicated, yes, but probably not worse than bi-turbo (sequential) setups.
The problem with the supercharger teaser was that there was no “code”, the 3D models and animations are more or less done, but there are no calculations for it whatsoever.
I can’t wait for Superchargers to be included. Something just “feels” wrong about a turbocharged V8. Not to mention I have a supercharged I4 in my car. Bring it! 
Daffy,

That one must be under somesort of binding key on your keyboard or something
