Torque rises by 37 percent.

Hennessey has developed a comprehensive upgrade package for the regular Chevrolet Corvette C8 to significantly boost the V8’s output. The mid-mounted 6.2-liter engine produces 490 hp and 465 pound-feet (630 Newton-meters) of torque in naturally aspirated form but those numbers have grown substantially after installing a supercharger. The LT2 with forced induction now pushes out a meaty 708 hp and 638 lb-ft (865 Nm).

With an extra 44 percent of horsepower and 37 percent of torque, Hennessey’s H700 package “extinguishes” the Z06. The aftermarket specialist means it packs a lot more punch than the 670 hp and 460 lb-ft (624 Nm) delivered by the flat-plane crank 5.5-liter “LT6” inside the Z06. The extra oomph was obtained by fitting a high-flow centrifugal supercharger, a custom air induction system with an air-to-water intercooler, and an optional cat-back exhaust.
