Single carb after would be better setup. CV or slide? I would go slide, I know how CV's work but not sure how it would work under pressure. If you keep boost under 10 I think you could get away with just pressurizing the bowls and not putting it in a box. On a blow though the gas does erode the impeller. How fast I don't know but people don't even put water injection on before the impeller. My turbo spins like 150k rpm even a little chunk breaks off it is goin supersonic into your leg. You will need a fuel pump and probly a rising rate pressure regulator. Cause say you are running 5psi of fuel (normal carb setup) and you put 8psi in the intake. You now have -3psi fuel. so you need the FMU or risin rate reg to bring it up. There are two different kinds a one to one which you would probly use and a 6:1 which is what my bike uses, to trick the fuel injection into puttin more fuel out than it thinks it is.
