I have a 2003 svt focus about 108,000 miles on it. I was think about rebuilding the engine to hold compound boost. Any thoughts? I like the power right now but it needs more. I dont know alot about engines but i wont to learn some more. Right now i have 13.5lb of boost with the supercharger plus a maxflow inner cooler. The results of a dyno was about 400hp. I want to get it more to the 750-1000 area what it the best way to do that? THOUGHTS?
