GT-R Motor Trend - Dyno Test: 2009 Nissan GT-R Makes 507 Horsepower... at least!

[Merc1]

We reveal Nissan's little white lie...


The hysteria surrounding the impending launch of Nissan's GT-R has prompted a mad rush to judge its performance. Various media outlets have attempted to test well-worn engineering mule cars and Japanese-spec vehicles with 112-mph speed limiters. Some have run acceleration tests on sloped track surfaces. Many an unsuspecting GT-R has powered the tire rollers and hub mounts of various dynamometers, registering widely varying power ratings. Most of the numbers generated and quoted have been heroic, which has served to heighten Godzilla's reputation as a mythological beast possessing supernatural powers. But some of these early tests have raised as many questions as they've answered. Over the next few days, we intend to answer them with rigorous testing of a fresh, production-ready U.S.-spec GT-R on flat, level ground.

Interesting, I remember reading another dyno run article on the GTR, and in that article, they say the GTR produce 480hp which is the exact figure claimed by Nissan.

There are so many of these running about in Singapore right now. Every well-moneyed boy racer is getting one because it's so affordable.

In the current Car and Driver they say that there are unconfirmed in Japan that GTRs have been dynoed to have 480 hp at the wheels. However, hp reported by manufactures is the horsepower at the crank. Which means if the hp at the wheels is 480, then the hp at the crank is about 565 which makes more sense given the speeds this nearly 4000 pound car achieves.
