there are at least 5 different types of superchargers, positive displacement and centrifugal are probably the most common. I wrote a paper on turbo's and superchargers for a class last year and I'm starting to forget stuff from that paper. the centrifugal supercharger combines the weaknesses of the turbo and supercharger, although one could argue those weaknesses are strengths with ease. the centrifugal supercharger works like a turbo, but instead of exhaust driven it is a belt. it has the typical turbo lag, but is by far the most efficient supercharger available. if I remember correctly, the novi 1000 adds about 100 hp.
Chibi, your question on HP Tuners forum and the resulting answer helped me get my 3.2 tuning worked out. I was having a hard time with my kr and timing advance graphs, but got it figured out when I saw your question and the answer. Welcome to the forum. I get crap for all the money I've put into my grand prix too, but I like it, and can drive it year round, so who really cares.
