Hey i'm new here, but I run a turbo'd cruiser with about $800 in engine mods and i ran a 14.2 @ 98 (2.24 60') with an Auto on street tires at orlando speed world. I am putting about 230-240 hp and close to 300 lb ft to the wheels. If I had slicks I could probably dip into the 13's. Just about anything you can do to a Srt-4 you can do to a PT as long as you have the room in the engine bay. Pt's just weigh 300-400lbs more than an Srt-4.
The guy in the video is from Vancouver canada, and is now about to install the motor stroked to 2.6 liters. There are videos out there of him running 11's. There is I guy I know in Ft Lauterdale running in the 12's with an auto pt cruiser on Slicks.
