The results are varying quite a bit from different sources. Blown motors are more sensitive to temperature differences, and the extra power probably makes them harder to launch and shift without wheelspin or wheelhop. What I've seen is high-12s and low-13s so far.
I was just reading that the '03 Cobra responds very well to simple mods - try 28 rwhp gain with just x-pipe, catback, and K&N.
