Torque has to do with displacement. The difference between 4.9 liter V8 and 5.0 litre V12 is very small in the TQ department. However, the stroke has gone down by 15%, allowing access to another 15% revs (7000 RPMs->8000 RPMs) so power goes up by a little more than 15% add in the 2% from displacement and you get close to the 20% found in the article.
