This comment may get me banned here... .... but I hate the S/C whine. Sounds like a wind up toy getting ready to go to me. I hadn't heard the whine in quite a while when I was planning adding a M90. Then I drove my buddy's SS and decided I don't want my car to sound like that.

Plus, I can have fun modding the car now, then when the time comes most of the mods will support and add to the turbo.
