For car buffs it's baffling (and pretty cool, too) to see a $70,000 Nissan weighing nearly 4,000 lbs whoop up on lighter, more powerful cars. The GT-R lapped more than five seconds quicker than a Corvette Z06 and 911 Turbo at Buttonwillow Raceway during Road and Track's test, and Car and Driver pulled off some pretty incredible numbers during theirs, running 0-60 mph in 3.3 seconds and the quarter mile in just 11.5 seconds. However, some have questioned the numbers. How does the GT-R, which has a weight-to-horsepower ratio 25% higher than the Turbo and Z06, beat both around the racetrack?

Motor Trend questioned the numbers too, and decided to check for themselves when they received a GT-R to review. They took the GT-R over to K&N Engineering in San Bernardino, CA, who strapped it to their in-house chassis dyno to see just how much horsepower the car was making. Three separate runs in fourth gear netted an average of about 430 horsepower at the wheels. Assuming a conservative 15% drivetrain loss, the GT-R is actually producing more than 500 horsepower and 500 lb-ft torque at the flywheel. That helps explain the numbers, but it won't give 911 Turbo and Corvette Z06 owners any comfort. Thanks for the tip, Jake!

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.
