I have not run it on a timed track, but the Hellcat was consistently hitting the mid 12's the week before in Vegas on stock tires.
The convertible pulls a bit harder now, as I changed the restrictive air filter set-up I had on it to a higher flow, cold-air induction. It made a definite seat-of-the-pants improvement from mid-range up.
Pics = New air filter and old air hat & filter(that reportedly only flowed just over 400 CFM)
