Compound Procharging!
What are your views on the results that would be encountered when the outlet of one Procharger was fed into the inlet of another Procharger the same size driven by the same crank shaft at identical speeds.
I would like your opinions on possible gear drive torque issues, inter/pre and post stage meth/water injection cooling, and any other phenomena that would be encountered.
Here's some info to get you going....
AIR are Procharger's Industrial sister company using unit similar in size to the F2 they are used in the commercial aircraft industry. Here twin F2 sized blowers can be configured parallel or series giving 15psi or 40 psi at 2500cfm or 5000cfm.

Below is my set up, will I damage it if I compound them or is excess air flow cfm compressed inthe manifold resulting in additional boost over and above the pressure created in the volutes.
That is to say if then engine at a particular rpm consumes 700cfm at 25psi but the blowers produced 1400cfm at 25psi what psi would I see? I suspect surge and stall still apply but to a lesser degree than with turbines due to the engine rpm/impeller rpm relationship.
