paxton sn93 blower! q's

[88GT4u2nv]

my buddy in canada who is building my new car has a paxton sn93 blower that he says he will throw on for cheap. says it has an upgraded impeller. whats are these blowers rated at psi wise? any ideas of what the upgrade might do for boost?

thanks, learning as i go.

Have one... love it. Cheap to maintain , cheap to rebuild... put a 3.75 pulley on it and make 6 or 7 psi..
just be sure to upgrade the fuel pump.
