The benchmark figure is said to be achievable via tweaks to the car’s standard mid-mounted LT2 V8 engine, with upgraded internals including forged aluminium pistons, a higher compression ratio and forged steel rods. Mated to this will be a specially designed twin turbocharger setup.
Further modifications necessary to achieve the figure safely and reliably include an upgraded factory dual-clutch transmission, while options include a full Brembo brake upgrade and adjustable Penske suspension. No price is quoted for the new package.
Hennessey’s upgrades come with a warranty for increased peace of mind, but for those with less ambitious plans the firm will offer a cheaper supercharger system upgrade for 700bhp, and a stainless steel exhaust upgrade. The standard, entry-level C8 Corvette puts out 495bhp.
There are visual modifications available, too, including a ‘CarbonAero’ carbon fibre body upgrade pack (as pictured).
