Tuners of different kinds and origins keep introducing more and more upgrade programs for the much-adored Chevrolet Corvette Z06 supercar. This time, the Troy, Michigan-based Specter Werkes company decided to equip the ‘Vette’s 7.0-liter LS7 engine with a twin-turbo system by Lingenfelter Performance Engineering.
With the twin-turbo installed, the LS7 gets its power increased from 505 hp to almost mind-blowing 800 horsepower. According to some sources, the engines impressive torque of 470 lb-ft (640 Nm) has also been increased to 800 Nm, but I failed to find independent confirmations regarding this claim.*
Oct 31, 2009 Update: Specter Werkes’ representative Mr. Matt Shipes has just replied to my inquiry. He says that the engine actually develops 800 TQ on the crankshaft, and the torque to the ground value is 669 lb-ft, which is still really impressive.
To make driving the car easier and safer, the tuner equipped it with StopTech STR big-brake package, sporting six-piston front calipers and four-piston rear calipers.
The package also features Corsa exhaust system with custom made Concord-style exhaust tips and some leather and carbon-fiber accents to the vehicle’s interior and exterior.
The Specter Werkes/Sports GTR tuning package, which is available on all C6 Corvette supercars, even including the outrageous ZR1 version, will consist of a new body kit with some parts made of carbon-fiber light-weight material, a set of HRE carbon-fiber wheels tipping the scales at just 22 lbs and fitted with Michelin Pilot Sport PS2 Zero Pressure tires.
