How much horsepower is enough? Many would say that the 725 horsepower in the Hennessey HPE700 Camaro should have enough oomph to quell just about anyone's desires for straight line speed, especially for a street car. Then again, we're talking about a car built by John Hennessey, who surely spends every waking minute concocting ideas on how to get every last horsepower out of cars. His latest creation, the HPE800 Twin-Turbo Camaro, puts out an amazing 815 horsepower and 788 pound-feet of torque thanks to twin turbochargers strapped to a 415ci stroker motor and a host of other upgrades.
Not enough for you? Hennessey will build you an HPE1000 version complete with a twin-turbo 427ci LSX block and just about their entire catalog of go-fast parts for Chevy's musclecar. They recently strapped one down to a dyno, and the resulting numbers are just plain ridiculous: 847 horsepower and 801 lb-ft torque at the rear wheels.
