Well, there is a video somewhere of Dan Millen's Mustang from Dearborn, Mi. of him leaving his shop, driving to a Burger King, getting food for him and others at the drive thru, then back on the 6 lane road back to his shop, (in the winter, with snow on the ground) the car has run in the 6.90 range at over 212 mph, has a full race interior on a 10.5 "W" Tire, with a 2nd seat I believe. Does this count?
it has a small block with 1 turbo, yep, only 1! and he is hard against Billy Glidden on race day where ever he goes. 8)
