Kleiner-Kurs is not a HP "as" dependant as other tracks, but it has straights and HP "still" matters, and 355HP to 620HP is a stratospheric difference that needs to be taken into account anywere execpt a g-kart track. However wasn't Sport Auto going to publish a ring and hockenhein test by Von Saurma about this time. If so I bet the fastest hockenheim 997S lap time will drop futher, I guessing to a low 1:14. How much did the SL65AMG do?
