its possible to have a fast 2.5, if you think in terms of the platform. In the grand scheme of things are they fast, no, in the contour/mystique/cougar platform its possible. I only know of 1 N/A 2.5 atx cougar thats faster than mine and ive only had it at the strip 2 times both in really crappy conditions
