Somebodies idea of stock may be different than someone elses. Fastest time published in a magazine was 13.85. 17 years later I would guess there aren't any stock cars left (that wouldn't have problems due to age) so it probably doesn't matter.
The beauty of these cars is not what they can run stock, but what they can run with only sligh modifications. Stock intercooler, turbo, injectors, etc, are all capable of high elevens with good air and traction.
