In case you guys are interested in the size difference between the V6 and V8 (3.2 and 5.5) superchargers, here are some photos of the two side-by-side. The 3.2 supercharger is only 35lbs, while the 5.5 monster weighs in at 55.

Here is some pics installed for comparison

 

No, they serve a purpose. That is where the smog pump lines run. Machine it down and you'll hit air.
