I can not get the info for the jeep srt 8 from the allpar site. The info below is from a road and track test mine is an 2008 model, I don't think it matters.

My personal best 0-60 mph runs are. 4.54 secs traction control on. in auto. and 4.27 traction control reduced(by80%) and in auto stick. Times were measured using a friends escort acelarometer(i think that's what it is called). Personal top speed according to speedometer (probably unreliable) 170mph and only very briefly. Only mods are Catback and cold air intake.
