Supercharge or Turbocharge?

There is no clear answer. SC's are often used on larger engines for packaging reasons as well: on a V8, slap low PSI blower on top, and if you are running < 7 psi no intercooling, or A/W in some of todays cars. Parasitic loss is not felt as much to drive the blower.

Turbo being exhaust driven, has less negatives on a smaller engine (the already soft down low is no softer), and you manage power output through proper engineering (A/R sizing for the power band you want, proper intercooling and engine management).

For V engines, you are typically looking at two smaller snails with compressor piping then joining at and A/A IC, then the intake manifold: doable, but far more complicated then a top mount SC typically.

If you were designing a 10 PSI system, either can work well from an output perspective when sized correctly.
