2010 mustang goes 8.97@153..
That's impressive for a "stocker" but like Calverts Thunderbolt I'm sure there isn't anything "stock" about it. NHRA doesn't regulate the injected cars because they can't police them. There are way to many variables in the electronics for them to possibly police so they just let them do what ever they want. Probably the same with the boost pressure, hell that thing could have upwards of 120 pounds of boost at speed.
But still 8's on a 9" tire is quite an accomplishment.
