ill break it down more simple for the retarded
air goes in at atmospheric pressure (14.7psi)
turbo compresses it 6 more psi (20.7psi)
then s/c compresses it again at(20.7psi)
now what should the pressure be even thought both syatems are only at 6psi. tell me that sir
Does the SC add 6 psi (PR of 26.7:20.7 = 1.3) which winds up being 12psig, or is it running at a PR that gives it 6psi over ambient like I laid out before that gives you 14.45psig.

Either way, you can't just add 20.7psi + 20.7psi, and one or way or another, the flow of the engine and the WG definitely comes into play for the SC and the turbo respectively.

I think you would have connected the dots by now, apparently not. Blowers aren't very efficient at 20.7psi.
