why isnt there any supercharger sounds?

ive been dying for a update about this such as the D series having a turbo or any other vehicles that dont have a turbo or supercharger but what i would really suggest is a supercharger whine

heres some ear orgasm sounds




but what i would think be a great detail for the turbo lovers as well is this

EDIT: at 2:32
the turbo not ending or overlapping and instead doing that i dont know the name of it but i think it would be a nice detail

Bug: sunbursts turbo not working and staying at -2 psi

 

Many people agree.

 

All sounds are WIP. Many currently in game are placeholders and there is a lot they plan on adding that isn't in yet

 

I really don't understand why there isn't one yet, considering we've had turbo spool sounds for a very long time now.

 

I would love for the legran to have bigger superchargers than just a stage 1. It would be way more fun.
