One lucky Japanese guy has already had his R35 GT-R on the dyno and confirms Nissan may have underrated the HP figures. The Dynapack hub dyno gave a measuremeant of 482ps at the hubs. Some are claiming that a figure of around 550hp at the engine is not too much of a stretch.

The interesting news is that the limiter (180km/h) kicked in in 4th gear so I’m not sure if they got a full power run out of it. From the graph it looks like there might be a smidge more in it.
