wrong, and your proof is below.
Twin charging works on the basis of pressure ratios. They multiply whatever they are sucking in by whatever their pressure ratio is.
For example your turbo boosts 10PSI which feeds into your super that has a 1.4 pressure ratio..
10PSI + 14.7 (atmospheric pressure) = 28.7PSI being fed into the supercharger
40.18-14.7= 25.48 PSI
So a 10PSI turbo boosting into a super with a 1.4PR = 25.48 PSI at the manifold. Total pressure ratio increase from atmospheric pressure is 2.73 by compounding.
Again, just to be clear... you are wrong.
