I know all about turbo sizing, its part of what I do. The one thing I would be curious to see is depending on what pressure he runs @ the turbo what it will do@ the supercharger, since technically this is sort of a compound setup. It should multiply what the supercharger outputs
Right when running compounding boost setups your multiplying the boost. So say your supercharger peaks at 18psi in the manifold with just the supercharger and you are feeding in 5psi from a turbo into the supercharger. Your total boost would be 28-29psi. Also keep in mind the twin screw design is mechanically limited to around 30psi on the exit side.
Can't wait to see the results once you get it all together. Good luck with the project!
14 psi feeding into the sc making 14psi at peak would be out 54 psi at the manifold... which that turbo could never produce anyways. Start out with a 5lb spring or smaller wastegate on the turbo to start off with and go from there! Happy boosting!
