oh yeah, 7.7 lbs to push for every horsepower available is better (FASTER) than 10.4 lbs for every horsepower. Not knocking the Elise at all, because it is without a doubt one of the greatest DRIVERS cars of all time, but on a long track, the Z06 with more HP and a higher top end will have the advantage, not to mention the slower curves where the Elise falls out of the VVTL range, the Z06 has the torque to pull itself out from down low.
Im predicting low 13 second times and almost 1.0 G on the skidpad if not more. And the ability to own every single car on the road on a tight twisty road.
