If a twin turbo pushes 10psi, does each turbo push 5 or 10?

Question

Pretty self explanatory. if i wanted to push 10psi, would I set each wastegate to 5psi or 10psi? Yea, i know, intercooler drop, pressure inefficiency, etc, but i'm saying at the turbos.

Answer 1

You would set them at 10 psi each. The turbos are paralleled (I'm assuming) so if each is set at 5psi, you will only get 5psi of boost.

Answer 2

These turbos are basically connected to eachother via piping or the intake. The pressure will be even throughout the system, therefore each turbo will put out 10 psi, and the oressure in the system will be 10 psi, The only thing 2 turbos does as opposed to one, is increase the volume of air moved, not the pressure

Answer 3

Set them the same. If they are both 10 lb/in2 that will be your max manifold press.
