I've spoken to folks with R/Ts just like mine (6 speed and the track pack option) who say they've run 13.13 @ 107 with the only mod being a K&N cold air kit. I have not witnessed it myself but I wouldn't doubt that it's possible in good air.

One thing that (besides the price) dissuaded me from the SRT8 was the lack of warranty. The dealer told me the power train warranty on the SRT8 did not exist.

Another consideration, the R/T has 376 HP. K & N claims to provide an additional 21 HP with their cold air kit. I don't know how true that is but for arguments sake, pretend it is. So that gives you 397 HP for the R/T. According to what I've read, the R/T is about 100 pounds lighter than the SRT. So theoretically, at roughly 400 HP and 100lbs lighter, the R/T starts to approach the SRT in power to weight.

I'm not knocking the SRT8s. I would love one too. I'm just saying the R/T has a decent bang for the buck.
