I've done a lot of supercharged B-series builds. I've got one sitting behind the shop with a custom CCW M90 that should make 500 WHP if I ever get around to putting a belt on it.
The big problems with the JRSC are the 4-rib belt; it's not enough, and heat soak, especially for track use. There was a guy in FL that would embed Laminova cores in the intake manifold, which worked okay for the heat soak, but that was a long time ago. I had one of his manifolds, and if I put a big enough radiator on it, then it would keep the temps down. The little M60 that came with a B-series JRSC also runs right off the edge of it's map well before you run out of RPM's, which adds to the heat soak problem.
Of course, if you really want to use a JRSC, then do a dual-sequential charger setup. That way you use the SC inside it's efficiency range and then switch to a pre-spooled (by the SC) turbo when you get in to the turbo's efficiency range. I made one years ago and it was a monster:

I don't know how it would fare for endurance racing, but I can't imagine any way in which it could possibly fail.
Everybody grab your brooms, it's shenanigans!
