A supercharger will cost you more than the parts that Bignoze has chosen, which sounds like he has a good plan. CR for a supercharged engine is around 8 1/2 to 9-1. You can't tell from your engine parts how much compression you have. You will have to either pull the engine and have someone do a liquid cc test or maybe see if you can find the person who built your engine and maybe they could tell you.
