Back in September we were "blown" away by the supercharged news from Hennessey Performance, when John Hennessey and his team of engineers took the 2016 Cadillac CTS-V from 640 hp to 800. In the meantime, they have pushed their Venom GT to only 1,451 hp. So the next logical step was to apply some of this knowledge into making the HPE 800 CTS-V even more powerful. Somehow, they are able to make 800 hp using the factory supercharger, which measures in at 1.7-liters of displacement. The recipe for more power involves more air, so they developed an all-new 2.9-liter blower. By force feeding almost three times the displacement of the Chevrolet Spark into the 6.2-liter V8, they have pushed the third generation to 1,000 hp at 6,300 rpm.
Of course, to make this incredible level of power, a host of other modifications were made in order to make it a consistent and reliable system. Forged pistons and rods replace the cast units, and the camshaft is a proprietary grind. Because the larger supercharger makes exponentially more heat, the intercooler and heat exchangers are all new. Stainless headers and high-flow converters make it so everyone will hear you coming, wherever your destination may be. Each engine is professionally installed and dyno-tuned at their factory in Sealy, Texas. This allows them to offer a one year/12,000 mile warranty as part of the package. If you would like to be bothered by tire salesmen calling your house 24/7, the HPE 1000 CTS-V has the power to vaporize the best rubber that money can buy. As soon as video becomes available, you will see them here on Autofluence.
