if i had to do it all over again, i would do a turbo instead of a s/c. so much more boost to be had with a turbo. after u get to about 15lbs it is very difficult to make more with a s/c. with a turbo, 30lbs is easily had. and there is not a whole lot of turbo lag like there used to be if you size the turbo correctly. and turbo doesnt take power to make power. runs off the exhaust. centrifugal superchargers build boost with your rpms. turbo builds boost much quicker to full boost lbs. and with a s/c you WILL have belt slip. had to fab my own extra pulley to help with slip. just about got it. but there is still just a little.
with that being said....i love my s/c. boost is awesome.
