The KO3 dies somewhere in the rev range and the car doesn't gain much speed thereafter. A Porsche I presume you redline before changing, but with the turbo I'm not entirely sure where the optimum gear shift point is. I assume just before the turbo stops boosting, but I don't know how to tell when that point is.
Perhaps I should buy an R32 instead so I can just drive like an orang-utan.
