hennessey is all over the Ls9.

Press release:


Not satisfied with the 638 horsepower on tap in your Chevrolet Corvette ZR1? Hennessey Performance has the solution. They've come up with a tuning package that includes a smaller supercharger pulley that increases boost from 11 to 14 psi, an upgraded intercooler, K&N intake, stainless steel headers, high-flow catalytic converters, and a reprogrammed engine management system that pushes output past the 700-horsepower mark. If that still doesn't meet your needs, Hennessey can keep the upgrades coming with high-flow cylinder heads and a more aggressive camshaft that puts the ZR1 at 755 hp. Hennessey's website says that 1000 hp is attainable, and we're guessing it involves a pair of turbochargers. Follow the jump to watch a video of the Hennessey ZR700 knock out an 11.03 second quarter-mile with relative ease. # Power: 705 HP @ 6,400 rpm
