Just to set this information down. While cruising the 300C forums for SRT-8 info, I came across a posted interview with the design chief for the 300, Magnum, and Charger, Mr. Gilles.
To my surprise, he posted. Why this matters to us is that he himself drives an SRT-8 300C. And we can safely assume he's had it for a while
The point is that he said in a post, referencing the SRT-8s power, to "wait til she breaks in at about 6000 miles, then it really flies..."
Now, keeping in mind the first 300C owner to 1/4 mile his car got 13.3, at way less than 6K, I wonder what a really broken in SRT-8 will do
(Damnit, Ekool, an evil grin smiely would really worked well there )
