i cant rember what version i bought but i only have i4s i6 and v8s and for the i engines only single turbo and for the v8s only twin turbo … i thought i could have twin and single for both and superchargers ? help plaese
i4’s, i6’s and v8’s are the only engine types available atm. Everything else will be ready for final game release.
Yep, you have everything that’s released so far.
ok cool thanks alot 
but just 1 thing its probably been answerd before but when will superchargers be realesed ? and will you be able to have bug catcher type induction on them and carburetors on top of them or will there just be twin screw / roots superchargers and centrifugal superchargers . ps i would rather carburetor and bug catcher super chargers like drag cars thanks for your time.
to see what is in and what is out, you can check this topic: automationgame.com/phpBB3/viewtopic.php?f=15&t=137
Currently the devs have said that the engine designer wont be a priority anymore. Main thing to do is getting the cardesigner and tycoon part mostly done and working.
