DETROIT: Chevrolet’s 2015 Corvette Z06 has been bulit for racing on any track you want to choose.
Well, if you’re Vengeance Racing, you do a massive, tire-frying burnout before you even leave the dealership parking lot. Then you drive 20 miles back to the shop and strap that baby on the dyno to see what it’s really putting out. Judging by the numbers, Chevy’s exotic-slayer Vette is making way more than the claimed 650 horsepower and 650 lb-ft of torque at the crank.
According to their post on CorvetteForum, Vengeance Racing measured 585 rear-wheel horsepower and 617 lb-ft of torque from their brand-new 2015 Z06 on a Dynojet rig. That would indicate driveline losses below 10 percent-or, more likely, that Chevy is quoting artificially low power numbers for the insane Z06.
We won’t know if this kind of output is par for the Z06 course until other owners start strapping theirs in for dyno testing, but the results are damned impressive. Of course, the folks at Vengeance are already conjuring up even more horsepower, bumping theirs up to an even more insane 660 horsepower and 663 lb-ft at the rear wheels after swapping in a cold-air intake, smaller supercharger pulley, and some tuning.
