Compound Procharging!

[exwestracer]

Compounding typically involves a large compressor section feeding into a smaller compressor for increased boost. Looking at your setup, you would have an un-avoidable pressure drop as the outlet from the first "stage" fed into the much larger volume of the second stage.



The result of this could be a huge loss in efficiency as both stages are spinning at the same speed (assumption), so the volume of air they are expecting to see is the same...?

Look into Pro-stock Diesel pulling tractors, as they routinely use 4 (!) compounded turbochargers to blow those John Deere engines apart...
