Dyno?

Though we didn’t get a chance to dyno-test the two slower GT-Rs, three of the five were so close in performance that we believe they accurately represent the GT-R’s capability. Clearly, Nissan is delivering more than the advertised 480 horsepower. And the most likely figure is about 520, which is yet another reason to bow to the best performance value since the Corvette Z06.

Tudo isto porque uma companhia faz os motores de uns carros muito especiais à mão e eles têm mais potencia do que o anunciado... Que chatice...
