    Huh. Okay, it's monster power from a ricemobile. One starts to Kevork itself but comes away looking still functional - just a blown hose.


    Those boost numbers are what I use to drive my nailgun for roofing. That's some serious pressure.


    All in all, it looks dumb - but halfway fun too.


    Gotta say this though - you couldn't get me anywhere near in front of those things on the dyno - I don't want to be anywhere like in front of it if a strap gives.

    I hate the music (well, what I got up to 2 minutes in), but I liked the blow-off valve, and need to figure out how to incorporate that with something I like.

    I refuse to even watch the video.


    What's next?

    - Engine dyno competitions?

    - ECU programming simulations?


    At this rate, playing a good driving video game is more interesting.

    I'm part of a Mustang club (yeah, yeah, I know... but it's good to know others with a similar sickness when you have a 25 year old Ford) and there are some guys in the club with 500-600+ HP Cobras that get the ooohs and aaahs at dyno days. But strangely enough, you never see them out the on the track, be it drag or course.


    On the flip side, a bunch of us with 250-350 HP cars are going out to California Speedway this weekend to do a track event and actually make some use of the comparatively little HP we have... and I think that's way more fun.

    Impressive numbers! i really hope that this catches on because it's safer then killing an innocent bystander. if the engine does explode in a shower of boiling coolant and bits of aluminum the only people that get hurt are the participants (jeeze that sounds bad the way i wrote that)

    @badco/LoJ: I agree to a point. The problem is that this almost completely removes the driver from the equation. This seems to be more a contest of who can buy and properly install the biggest parts, reaction time and driving ability no longer factor in.

    I'm torn between mocking them for the sheer retardedness of this "sport", and congratulating them for finding a way to take their ricemobiles inside and be stupid without endangering/annoying the public at large.


    I'll split the difference. I'm proud of you idiots.


    P.S. Is it wrong if I secretly hope that they forget to hook up the exhaust vent once and Darwin out the whole crew with CO?

    @maximum-sienna haz a NA V-6: I would assume no such thing. these are street racers, if they can get 5 hp by pulling the cats, they will. If they have to pass inspection once a year, they'll keep them to reinstall for the occasion, but I'd quicker assume they've been removed than I would assume they're still there.

    In reply to Hyper Power International Dyno Claims First Accurate Measurement Of Driveline Losses With Nissan GT-R
    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: 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.
