Out of the box, the $110,000 ZR1 Corvette gives you some pretty incredible stats, like 638 horsepower, 604 ft-lb of torque, a zero to sixty time of around 3.5 seconds and a top speed somewhere north of 200 miles per hour. Just a few years back, those numbers were reserved for cars with a prancing horse or a charging bull on their logos, with the accompanying increase in price. The Corvette ZR1 really does bring near-supercar performance to a broader audience (although $110k isn’t exactly blue collar), but that’s simply not good enough for some buyers. It’s one thing to show taillights to a Ferrari F430; it’s something else entirely to go toe to toe with your ZR1 against a Ferrari Enzo. Want to see a ZR1 capable of taking on Italy’s best? Hit the video below.
If you’ve got that jones, and if you have a sufficiently large balance in your bank account, Hennessey Performance would be happy to build you a 755 horsepower ZR1 Corvette. Dubbed the ZR750, the car gets its horsepower increase from ported cylinder heads, a hotter cam, a ported throttle body, more boost courtesy of smaller supercharger pulleys, a revised intake, headers and high-flow catalysts. The mods drop the zero to sixty time to 2.9 seconds (assuming you can get the tires to hook up) and yield a quarter mile time of 10.7 seconds at 139 miles per hour. The tops speed is increased to 224 miles per hour, and the zero to one hundred fifty mile per hour time is decreased by four seconds (to 13.1 seconds). Pricing isn’t listed on the Hennessey website, but I can guarantee the kit plus a ZR-1 Corvette will set you back far less than anything with a horse or bull on it.
