And to keep calling it over hyped is just ridiculous, stop hatin. The whole hyped about the GTR is it's performance not the hp figures. The performance figures where out way before the hp figures came out. So far ony one mag has confirmed the 0-60, lets wait and see if the peformance live up to what they're publishing.
You directly follow this post that cautions us all not to get carried away with a post providing more of the very details that establish the case that the car is clearly under-rated. Dislexia much?
Let's not keep going back to the IS-F. The simulations with the incorrect final drive pointed to a very likely under-rating of the IS-F. The revised simulation with the correct FD as well as the actual performance numbers still points to a potential under-rating. Bruce A's simulations also pointed to a potential under-rating of the IS-F. If it is under-rated it is slight, 5-20 hp. Get over it.
Let me be perfectly clear on this one. The GT-R is under-rated, period. There is simply no way it can achieve the numbers it has at its stated power and weight figures. The regression analysis shows it, 1/4 simulation times show it and the dyno now shows it as well. Even accounting for jworms good point about the specific dyno type there is still no way the resulting dyno numbers are consistent with a stated 480 crank hp. How much evidence do you need exaclty?
