Supercharged Corvette Z06 Puts Down 890 Horsepower
This 2007 Corvette Z06 is the realization of one man's adrenaline-infused dream of a monster 'Vette.
The true satisfaction of owning your dream car takes a lot more time and money. For a 15-year-old Bill Cobb, he was close to having his dream Corvette at his disposal. Unfortunately, his father realized the adverse effects a Corvette could have on a teenager. In a flash, Cobb's dreams were crushed. The 1978 Silver Anniversary Vette was gone, sold before Cobb could ever get behind the wheel and muscle the Vette around. But, as with most happy endings, Cobb's tale of Corvette ownership and fulfillment starts with perseverance.

Good Things Come to Those Who Wait
After his father sold the '78 Vette, Cobb found a way to stay near the Corvette scene. He found a job with John Drahos of Corvette Conspiracy and absorbed as much as possible. His time around Drahos left an even deeper impression on Cobb and further fueled his desire to fulfill his boyhood fantasies. In 2006, Cobb made the triumphant march to his local Chevy dealership and ordered his prized 2007 Corvette Z06.
Sliding Down the Rabbit Hole
As is so often the case, Cobb drove his Corvette and loved it. After a few years of ownership, he began hearing about the high horsepower builds coming out of Corvette Conspiracy. Shortly thereafter, Cobb decided to join the party.
To prep the Z06 for the incoming horsepower, the LS7 was plucked out and sent to ERL Performance. Among the laundry list of upgrades the engine received were an upgraded crankshaft, pistons, ported heads, sleeved cylinders, and a FAST intake manifold. Fuel injectors were an obvious install given the influx of air headed to the engine. With the groundwork laid, a Procharger D-1SC centrifugal supercharger was thrown into the mix. In stock form, the LS7 put out a then earth-shattering 505 horsepower. With the added sauce, Cobb's Z06 now throws down 890 rear-wheel horsepower.
Hiding in Plan Sight
Anyone who knows anything about Corvettes will be able to identify Cobb's silver Vette as a Z06. To the uninformed, this build is just another silver Corvette, something that could be owned by your dentist or local real estate agent. The unsuspecting, over-eager teenager in a V6 Mustang would be terrified to know what kind of weapon lies beneath the clamshell hood of this silver bullet.
Subtle Styling Mods
In keeping with the sleeper exterior appearance, the only noticeable change are the HRE wheels. The wheels measure 19x10 in the front and 20x13 in the rear. They're wrapped in Nitto Invo tires measuring a massive 345/25R20 in the rear.
Four Tips, Must Be a Vette
890 wheel horsepower is a hell of a soundtrack. That raw power is amplified by a Pfadt Tri-Y header system and X-pipe. Towards the rear, Billy Boat Fusion mufflers complete the exhaust system. The stock Z06 transaxle was left unmolested but the torque tube of the driveshaft was reinforced to meet the new power levels.
Familiar But Improved
At passing glance the interior of Cobb's Z06 is standard Corvette fare. Underneath the stock Z06 seats and tucked away beneath the carpet is a layer of Dynamat, aimed at toning down some of the LS7's newfound fury. Other minor improvements include upgraded stereo speakers and a hidden fuel pressure gauge.
Dream Come True
Now that Cobb has built the Corvette he waited decades for, what's left? Well, in 2013 he took home Best in Class at the Piston Power Show in Cleveland. As for the Vette's day-to-day role? It's Cobb's stress reliever of choice. Hard to argue with the form of therapy. Especially since I don't think there's a prescription pill that would go from 0-60 any faster.
