    But if the car is in neutral, the transmission isn't spinning. So this device just measures the drag of the driveshafts and wheels spinning. PLUS... aren't driveline losses really just because of the rotational inertia of the parts of the transmission? I think that the act of accelerating the spinning parts in the transmission is what takes all the power. Otherwise the transmission would get really, really, incredibly hot. There isn't that much friction in there...


    Color me unimpressed.

    @nick2ny: It does get hot. That's why you have transmission oil coolers.

    @nick2ny: Depending on the transmission, but it's gears are still spinning to some extent. While your driving gear is out, the rest of the trans still rolls with the drive shafts. This is why on an automatic car that if you tow it and the drive wheels are spinning, you must disconnect the drive shaft. Even in N, the trans gears are spinning. Of course, with the enigne off, there's nothing to pump the trans fluid and that burns up trannies while towing.

    I like the name: Hyper Power International.


    Makes me think I can harness the energy from my children and sell it somehow. Is that tantamount to child labor? They're just burning it off anyway!

    I can measure drivetrain loss on a GT-R too: use launch control? Lose your drivetrain.

    It would be interesting to see a third party test the manufacturers claims by running a car on this rig, pulling the engine and running it on a stand dyno, then comparing the numbers.

    @Mike the Dog: I thought the whole point of this rig is that they don't need to pull the engine.


    As for the numbers? From what I'm reading, it appears to confirm that Nissan's numbers are correct.

    @Doshu: I meant as a means of independently verifying whether or not their method of calculating driveline losses was somewhat accurate or just a bunch of BS. It's easy to say you're calculating driveline losses accurately when you know what the numbers on both ends of the equation should be.

    @six: The GT-R's GPS receiver knows the positions of all the Hyper Power International dynos in the world. When it senses that your GT-R is on one of these dynos, it automatically de-tunes the engine.

    Ask the GT-R driver to do it four or five more times. Barring radical clutch failure, the Viper can pull off hard launches all day long. The GT-R will puke up something metallic and expensive.

    The Porschebunker has already parachuted a strike team in to investigate this obvious, pathetic fabrication. Perhaps, in the dead of night, they switched transmissions, rendering the Viper nearly immobile and unable to complete a second run.

    Wow, the commentariat has really gone into the toilet as of late. People shitting on the Viper without knowing a thing about the car or what it can do/has done.


    A stock ACR Viper has already done an 11.07 @ 129. With better track/weather conditions its a 10 second car.


    And I call BULLSHIT on the GTR. Fastest stock time I've seen is 11.40-11.50's (Road & Track, Edmunds.com). R&T got a modded GTR to 11.10 and there are some in the 10.50's heavily modded, driven by skilled drivers.


    So, if you want to "easily outpace" a Viper ACR with your Godzirra, you'd better kick down $150-200,000 for car and mods and don't forget your pro-grade driver.


    Right off the showroom with only tire pressure adjustments, both cars should be pretty close in the 1/4 mile. This video is completely misleading.

    @Uncle Bo, averting foreclosure: There is also the variable of engine output... Godzirra also has hand made engines-- guaranteed to produce at LEAST 480hp, though some make more than others...


    I dunno, I credit AWD and fancy TCS for the pull, and the ACR could've benefitted from TCS. But what do I know, I've only driven the ACR in racing sims.

    @Uncle Bo, averting foreclosure: So how's it BS? Did someone photoshop the GT-R's ET on the video? Or do you think the GT-R got the benefit of some stickier tires and maybe a little extra boost? Because really, it's not that impressive for the Viper to merely be competitive with a car that's down 150 or so horsepower on it.

    @elwood:

    1. The "victory" is not indisputable. It's anything but.


    2. Equating this video with the car's Ring times is also baloney. The Viper was driven by WTCC pro Tom Coronel, who has raced on the Ring many times. The GTR was driven by Tochio Suzuki, Nissan's chief test driver for the GTR. Who was driving the two drag racing cars, Dil and Do?


    3. There is no f'n way that GTR is putting out only 480hp, or whatever it came with stock. Prolly more like 550-600 hp, similar to other modded cars with similar proven ET's.
