Testing cars for power ratings is a tough and tricky business - accounting for different conditions, locations, equipment and techniques can make it tough to generalize results. And to make matters worse, there is often a lot of guesswork employed to get between real, delivered wheel horsepower and output at the crankshaft, or vice-versa. A recent test of Nissan's GT-R has answered some of the ongoing questions of how it performs so well, however, and taken a good bit of the fiction out of the process. Rumors and reports from around the web have been claiming Nissan's stated figures for the GT-R's twin-turbo V6 are understated ever since it began its remarkable climb up the many performance charts.
