Instead of just doing a 3.5" pulley, new PCM, 180* stat, and headers, I'm looking at doing an intercooler and a smaller pulley with a new PCM and a 180* stat. I was looking at W Body Store stage II intercooler. I was wondering if anyone knew anything about this intercooler. I`d get it with the machined lower intake and the intercooler rails. So I have a few questions. How small of a pulley would I be able to run? Is the W Body Store stage II intercooler a good intercooler? Will it fit under the hood of an `04 supercharged Monte Carlo? If I got it professionally installed, how long would it probably take for a mechanic to install it? How much crank horsepower would I be able to expect?
