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.
