Nissan not lying about GT-R horsepower

Last year, Motor Trend has estimated the Nissan GT-R35 is going to produce about 507hp and it is not match the factory specification. Now, Motor Trend plans to have another round power testing on the Nissan GT-R35. The key to this latest round of testing is the use of Hyper Power Dynamometer's DYNOmite, which allows testing not just of engine output, but of powertrain drag. After a dyno pull, instead of ceasing to record data, the machine records the slow-down period, and measures the drag due to the car's powertrain, including engine, transmission and wheels.

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.
