Just as an aside, the GM diesel trucks [dirty GM's they are called], run a supercharger and turbocharger together. They are a V6 and make as much power with this setup as much bigger motors. Oh and they are two stroke deisels as well. Downside is they do like a drink!!!!!
PS They have been around for a long time, +30 years, I'll do a search and confirm when they first came out to confirm that, but I drove one at least 30 years ago [there goes my age now].
