Nissan GT-R dyno: 475hp At The Hubs

[MeraBoy]

A few days ago we were talking about Nissan wanting to get the GT-R to an SAE-certified 480hp so it would match the Porsche 911 Turbo, one of its chief rivals. It looks like that should be an easy feat if the dyno numbers coming out of Japan today are solid - and it looks like they are. According to testing done on a Dynapack dynamometer, the new GT-R pumps 482PS (475hp) to all four hubs, with torque peaking at 580Nm (428lb-ft) at the hubs.

Assuming parasitic drivetrain losses around 15% - although the loss could be even larger given the GT-R’s all-wheel drive platform - that would put power at the crank around 550hp and 495lb-ft of torque - absolutely insane numbers for a 3.8L engine, twin-turbo or not. Suspicious? Examine the photographic evidence of the testing, complete with shots of the dyno screen (above & below).

While these numbers seem to fit more aptly with the GT-R’s 3800lb curb weight and its scorching ‘Ring times, it still seems odd that a car with a drag coefficient of 0.27 would top out at anything under 200mph with 550hp under the hood. Maybe there’s more to this story than meets the eye.

Theres definately more than meets the eye and not just looking at the figures, ie: how well the car puts the power to the ground using newly developed techonlogy, how well the chasis was designed, how much quicker the gear changes are, tyre angle setup, etc etc etc... every bit counts when ur looking at serious lap times..
