Nissan GT-R dynoed at 475 hp, 428 lb.-ft. of torque - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Japan's BestCar buff book grabbed the keys to a new Nissan GT-R and made for the nearest Super Autobacs. Once they arrived, they mounted Godzilla atop a Dynapack chassis dynamometer, removed the wheels and laid down a few runs to get power figures straight from the axles. The numbers are due for publication in the mag's December 25th issue, but our new friend Jeff made Christmas come early.

The dyno chart shows a peak output of 475 hp at 6,115 rpm and 428 lb.-ft. of torque at 5,130 rpm. Those numbers are incredible close to Nissan's claim of 480 hp and 430 lb.-ft. of twist, but we'll have to wait until a few lucky souls slap the GT-R onto a set of rollers to get some idea of wheel horsepower and torque figures.

Looking over the chart shows very little happening before 3,000 rpm, which is contrary to a number of driving reports we've read so far. Turbo lag has virtually been eliminated on many new models, the GT-R included, so we're assuming that the Dynapack at Super Autobacs wasn't paying attention until later on in the rev range.

That is amazing!

Considering that manufacturers typically use SAE net flywheel hp figures for advertising purposes, a 5hp difference going from advertised crank to awhp means that the VR38DETT has been underrated.

It cant be the exact AWHP without them can it?
