Twin turbo question

[434nova]

I know this is probably a simple answer but here is my question. When running 30 #s of boost with twin turbo does that mean each turbo is producing 15 #s for a total of 30#s or does it mean each turbo is pushing 30#s of boost. Thanks

depends on how you are measuring, if it is at the manifold, would the MAP sensor be the source of the pressure? If so, then it would be combined.

They are both pushing 30 PSI but, each is only supplying 1/2 of the total CFM

It would depend on what kind of twin turbo setup .. the turbo locations and mounting arrangement will vary the answer to your question.

Huh??

this is a trick question, and your to old to understand.

I must be...
Perhaps the op can enlighten us as to the how/why.........

Maybe an expert like Bison will jump in but I don't think each turbo is "producing" 15 psi. They are both putting out equal amounts of air (cfm) which creates pressure (psi). Then if you really want to complicate it we could throw compound turbo system into the mix??

Huh??

Sequential .. twin stage ... triple stage ...

its a loaded question .. that's what I was getting at .. you can have 1 turbo put out 10 psi and another put out 30psi and another put out 90 psi

pressures will be the same (30 psi) and each will do half the flow...assuming the inlet pipe and outlet pipings have equal friction loss AND they combine into a common plenum. If you vary the piping system, the pressure's at the turbo will vary accordingly to reflect any additional losses, but where they combine they pressure will be 30 psi.

There turbo's will need to be sized for that application as well. Just because you add a turbo, doesn't mean you get twice the flow....
