My car's times are pretty good, I 'm happy with the way the car runs...I think I have an exceptionally strong motor at my 136K...though I wish I had your extra horses though...it would easily be a high 13-sec car....so I would like to think !
Is your dragstrip near sea-level? Some guys in the mid-west USA seem to pull 14.4-14.5s at the higher elevation with their 500Es. Its all good though ...14-sec sedans are darn fast enough...
