This is obviously a joke, but I have seen nine sec cars go at it on the street. As for how fast of a mustang can be driven in street trim well it depends on what you call street trim. Look at NMRA wild street those cars have to be street legal on DOT tires and have to drive 30 miles inorder to run then run without poping the hood all the while having full interior and there are several of them running eights and nines. Hell with a ET street and maybe a cam swap my car should go 10's and I will be driving it this way and I am sure I will be participating in some late night R&D.
