    Ok so I know this has probably been discussed a few times but I couldn't find anything on it so I'll ask. I have a saleen series VI blower on my 2006 gt with a 3.4 pulley. I am really considering a 3.2 pulley and tuning it up to almost 500rwhp. The car has about 64,000 miles on a stock block...
