I had a MY00 and had the Comptech supercharger with aftercooler. I was putting down 310 to the wheels with the help of the smaller pulley. I can honestly say from a roll, it's gona take a nicely modified WRX to hang with it. I know my STi would kill it from a dig (341.4 awhp) but from a roll I don't know how I would do. The fun factor is 10 times better with the S with the top down, but it is a very tight fit. My wife hated that car and loves the Subaru (feels safer) much more.
