I know it's a little on the large side, but having a nice sedan that can run 12.75@108 with only a homemade intake and a tune is impressive:
Once the tuning gets better and you do some exhaust mods, I bet low 12's would be relatively easy.
It sounds like a version of the same motor is going in the F150 next year. That could be a lot of fun
They also make an
ecoboost Flex. It runs 14.6 stock. I bet with mods you could easily make it run low 13's. Not bad for a 4500lb, 7 seat people hauler
