MotorTrend says Nissan not lying about GT-R horsepower

Last summer, Motor Trend estimated that the Nissan GT-R made at least 507-horsepower at the crank, which is quite a bit more than the manufacturer's official 480-horse rating. Now, MT decided to put to rest the firestorm it created by strapping yet another GT-R to a new type of dynamometer that's reportedly capable of calculating exact drivetrain losses, something that had previously been nothing more than an estimation. Three runs were conducted, and Godzilla delivered figures that were consistently within just a few percentage points of each other. So, what's the scoop?

According to MT, the average of those three separate dyno runs reveals that Nissan's supercar is delivering 485-horsepower @ 6050 rpm and 470 lb-ft @ 3800 rpm. That's nearly spot on for horsepower, but a good deal more torque at the crank than its official 430 lb-ft. -- we're not complaining. These tests also prove that there are indeed significant losses due to the GT-R's twin-clutch, all-wheel drive configuration, though that's also what helps launch the supercar from a dead-stop so quickly. Thanks for the tip, Franz!

Nissan GT-R meets the dyno, a 997 Porsche Turbo and an E92 BMW M3

It was only a matter of time before the first consumer-owned Nissan GT-R in the U.S. made its way onto a set of dyno rollers. Edmunds Inside Line made the call to Harman Motive, Road Race Engineering (RRE) and Daryl Alison of JSpec Connect to organize a day of data collecting recently for the import from Japan. Harman and RRE happen to each house all-wheel-drive-capable dynos, with a Mustang and Dynapack, respectively. The two units were chosen because they each utilize different means of measuring vehicle power output, making for a range of results that can be more readily used for comparison purposes. And compare they do as a 997 Porsche 911 Turbo and 2008 BMW M3 happened to show up at the testing facilities that very same day, fancy that. Follow the jump to get a handle on the results.
