s trim and sc trim differences
 

i was wondering if anybody could tell me the difference between a s trim vortec and a sc trim vortec and how much boost will the sc make.

If you are familiar with the a-trim... the sc replaced the a. Its now the base blower.

oh ok i know little about the a trim. can you change pullies on the a trim to get more boost or are you stuck with 5 or 6 lbs. i thank i read on some site where a guy was able to do that but im not sure. thanks rbatson
