As a new '07 SRX owner I'm interested in any information from forum members regarding available performance mods for the V8 Northstar. I haven't seen much on this so maybe you could point me in the right direction. Don't get me wrong, 320 hp is nothing to sneeze at but I always like a little more. I have made air intake, exhaust, etc. mods to my Grand National and Corvette and would hope there is some room for improvement with this great engine and chassis. Any help kindly appreciated!
