The team at Vengeance Racing has certainly been excited to take delivery of its new 2015 Chevrolet Corvette Z06. Upon delivery, there was a massive burnout, which was followed up with a run on the dyno. That run produced power figures of 585 horsepower and 617 pound-feet of torque at the rear wheels.
That translates to quite a bit more than the advertised 650/650 being touted by GM. Now another group have plopped the C7 Z06 on a dyno, and the results gathered by High Tech Corvette are just as impressive.
This Z06 produced power figures of 572 horsepower and 589 pound-feet of torque at the rear wheels. According to High Tech Corvette, their dyno was calibrated based on a number of factors including weight and weather. Additionally, the engine was running hot to account for real-world driving conditions. Per their YouTube video, this method of testing produces the truest results to what a driver can actually expect.
Going with that standard 15% powertrain loss, this would put the High Tech Corvette numbers at 658 horsepower and 677 pound-feet of torque at the crank. That's closer to the General's numbers but still greater than advertised... and that's a wonderful thing.
