    Default First Privately Owned 2015 Corvette Z06 Dyno Numbers Are Surprisingly High - See more

    ...If we use the traditional 15% drivetrain loss ratio and do the math with the actual rear wheel power figures from the Vengeance Racing dyno sessions, the numbers are significantly higher than the official specs from GM. 585 wheel horsepower in a drivetrain that is 85% efficient would be making around 688 horsepower at the crankshaft and 617lb-ft of rear wheel torque would translate to a bone chilling figure of 727lb-ft of torque.
    No production road car in the world boasts a torque figure like that. Not LaFerrari, no the McLaren P1, not the Lamborghini Veneno, not the Hellcat Challenger, nothing. 727lb-ft of torque would make the Corvette Z06 the most powerful production road car in the world in terms of torque. However, GM rates the car at “just” 650lb-ft of torque so that claim is left unclaimed.

    Aside from their cost I never understood why people race them.

    Someone posted a video yesterday on the vette forum showing roll races between a C7Z and a 2013 viper and the viper beats the vette time and again. I just looked and it's already 35 pages long LOL. Wow, people really care about hp wars! How much is enough for a street car? I had to laugh when I read someone post about how they were going to wait for the C7 ZR1 because they were disappointed the C7Z was beaten by a viper.

    Weird sentence since torque is not power.

    So maybe we should call it the most forceful production car.

    No chance that the dyno is just optimistic, eh?
    I remember my bone stock GS430 "put down" 287hp/300tq "at the hubs" years ago during it's baseline.

    Took one look at the dyno operator who suggested it must be a "strong runner".

    Not really. Torque," power", and horsepower, all refer to the ability to move an object over distance.

    "Horsepower is simply an extrapolation of torque applied over time. When an engine is measured for its power potential on a dynamometer, horsepower and torque are not measured as separate entities. Rather, torque is measured, and horsepower is then calculated given the torque at the specific RPM level."(see link at end of post)

    Torque is the amount of work that is being generated over one foot of crankshaft rotation, and horsepower is the amount of work that is generated over a one minute duration. So, along with an adjustment for the rotational radius of the crankshaft, torque multiplied by rpm = horsepower. One crankshaft revolution in a low torque motor may not amount to much, but 200 of them every second (12,000 rpm) sure can.

    See the perspective on "power" in the last paragraph of the article below:

    So the Viper wins every time. But who cares about drag races? Why on earth do you need 700 whp and 700 tq? Does that make you a better driver? Well no, it makes you a dick measurer . . .

    Ah, the age-old argument, propagated by age-old men whenever there is progress: you don't NEED that.



    I call shenanigans on the dyno. They probably took it to Church.

    Most people don't care about being a better driver. And most Americans only care about drag races (stoplight to stoplight). They want the "fastest" car and they're willing to pay for it hence the hp wars which have been going on for decades. I've had a couple LS engines with superchargers, one factory and one I modded myself. I prefer my engines naturally aspirated and for that reason have no interest in a C7Z or ZR1. Now a flat plane crank 500 hp V8? That sounds cool.

    My Honda S2000 measured 243 HP at the hubs after basic bolt-ons / ecu reflash on Church's dyno...

    Needless to say, I'll have to agree that the dyno was probably pretty optimistic.
