Additional horse power through super charging and twin turbocharging

Hi there,

I recently acquired a 2018 Volvo S90 T4 Inscription (essentially full option), which has 190 BHP. Since it also
has twin (?) turbochargers and super charging, I was wondering how much additional horse power
and torque (if any) is added through these extras ?

Thanks !

T4s have about 30 less lb/ft of tq and about 60 less HP than a T5. And apparently only FWD? And noticeably better MPG ratings.
