I'm looking at hooking my G2.5-550 turbo on a tiny supercharged engine which makes 80-105 ft-lbs 1000-5500rpm by itself. I want my final result to be 433whp with torque not exceeding 250ft-lbs through the very wide power band. The supercharger pipes directly into the intake manifold so some check valve pressure regulation seems like the solution. Ideally, I want to blend the S/C and T/C for only 3000rpm, then shut out the S/C. Anyone here have experience with doing a twin charge?
