Vortech and HKS make the best superchargers for the VQ but most often guys will switch to turbo when they want big horsepower.

Curb weight on a Z is around 3300lb.. maybe 3200 on the track edition but add a supercharger and other mods and its easily heavier than an M3.
haha there is no way that supercharger set up =200lbs lol especially being a centrifugal set up. (sc12 set up for my MR2: roots blower, pully, bracket, Belt, piping and intercooler weight ab 100-120 lbs, and that blower is an old heavy 1.2l roots style) if anything it would weight ab the same as a stock m3, and thats giving alot toward your arguement. still doesnt equate for the lack of power compared to what the Z should be producing. despite Z owners oppinions the kits still dyno 370-380whp..thats almost 80whp more than the M3 and ab 120 more ft lbs tq.
