Super/Turbocharging a M50/S50

What effective compression ratio do you end up with when you put a
typical forced induction setup (5-6 lbs of boost) on a M50/S50?

I believe the standard compression for the S50 is roughly 10.5 to 1.

Also, I hear most people want an ~9 to 1 compression pistoned engine(3.5
liter big six
is obviously perfect).  Is that because the forced induction @5-6lbs
would only reach ~11 to 1?

Thanks
