The 14ers have also been done in self-supported. In 1995, Peter N. Jones did them all self-supported in 16d13h43m. Jones did all the driving between trailheads himself, and so could not use the many short-cuts that supported people have taken advantage of. And of course he couldn't sleep during the drives! He followed the 3000' rule.
