Run a meth kit with the supercharger and your engine will be fine I put between 5000-10000 on it before it blew up the trans and I took it off, the engine was perfect before and after. Maybe even cleaner after from running the windshield washer fluid through it. Def add the Meth kit, its amazing how much heat that will suck. You will NOT detonate even in Florida heat after a couple miles of beating on it. In fact I was in boost for maybe 30 seconds on a 150+mph run. Then I drove normal about 5 miles home, my intake manifold (not just the piping) was still just BARELY warm to the touch. This is after having driving it for about 20 minutes, and having been out of boost for about 5-10.
With a turbo you're going to have to fabricate quite a bit for it and you will have to build a bottom end, but it will also be a HELL of a lot faster, see boost sooner than a centrifugal, and the other innumerable advantages. The only reason for the supercharger is cost, fabrication time, and you don't need a bottom end with a Novi 1000.
