This Corvette Z06 Adds Twin-Turbos, Pumps out 1,400 HP



The last-generation Corvette Z06 was a special car. It boasted a 7.0-liter V8 engine, produced 505 horsepower, and could blast you from naught to 100 mph in eight ticks of the watch. Heady stuff. But someone thought, “Nope…not enough.” 
That someone is the owner of this 2009 Chevrolet Corvette Z06, which now lets loose a pavement-pounding 1,400 horsepower, thanks to the addition of two turbochargers. Better hold on tight. It’s not a car for the faint of heart, but if you have enough coin…it could be yours. This American cruise missile recently blasted onto eBay.

So just how does a Corvette get ratcheted up and tuned to deliver 1,400 horsepower. In this case, it started with a new engine. According to the owner, the Z06’s calling card LS7 was ditched in favor of a built racing engine—crank, cam, pistons, heads, and more. Then, the ‘Vette was fettled by Georgia’s Vengeance Racing, which equipped the bombastic V8 with two Precision 6766 turbochargers, an air-to-water intercooler, and new x-pipe exhaust.

According to the listed dyno results, that setup dispatches a resolute 1,419 horsepower and 1,321 lb.-ft. of torque to the rear wheels, handled by the Z06 six-speed manual and a new carbon fiber driveshaft. A ProEFI engine management system and boost controller can vary that power output between five different tunes, all the way down to only 800 horsepower at the wheels.

It isn’t all straight-line speed though. The racy Z06 now boasts corner-taming Pfadt adjustable coil-over shocks and springs, as well as anti-roll bars. Stopping power comes courtesy of Corvette ZR1 carbon ceramic brakes. Chompy.


Inside, the ‘Vette is said to boast a mix of leather and Alcantara, under which a substantial amount of soundproofing and heat-eschewing material has been added. A good thing too, considering two spooling turbochargers at full chat ought to create quite the audible and thermal punch.
