2007 Katech Corvette Z06

CLINTON TOWNSHIP, Mich. – Katech Performance has made the Corvette C6 Z06 even better with more power and enhanced induction, cooling and exhaust. The C6 Z06 vehicle package (KAT-A4691) promises 600+ horsepower and fine finishing touches for enthusiasts who desire a truly unique Corvette.

To develop the package, Katech Performance consulted with endurance racing legend Dick Barbour of Dick Barbour Racing. Barbour’s accomplishments include multiple 24 Hours of Le Mans and 12 Hours of Sebring class victories as well as three Sports Car Club of America (SCCA) championships.

“Katech’s own rich motorsports history includes more than 50 driver’s and manufacturer’s championships,” said Caleb Newman, vice president, director aftermarket operations, Katech Performance. “The C6 Z06 package draws from our collective expertise. We’ve crafted a vehicle worthy of the most astute Corvette aficionados.”

The C6 Z06 package features a Katech Performance “Street Attack” LS7 engine with Katech forged 11:1 pistons, solid bushed titanium connecting rods, upgraded camshaft, high-lift beehive valvesprings, ultra-light titanium retainers and ported cylinder heads. Other modifications include a Katech adjustable billet aluminum belt tensioner, coil relocation brackets and paint-matched valve covers.

“Our Street Attack LS7 produces 600 horsepower for the C6 Z06,” said Newman. “That’s an increase of nearly 100 horsepower over stock. What we’ve created is one of the industry’s most powerful yet durable and civilized engines. It’s a thrill on the highway yet reserved on city streets. Our C6 Z06 is a true 600 horsepower daily driver.”

Newman went on to explain that each Street Attack LS7 is hand built by the same technicians that produce championship winning engines for all Katech race programs. Each is meticulously calibrated and dyno-tested before leaving the facility.

Further C6 Z06 engine and exhaust enhancements include a Ron Davis custom aluminum radiator with integrated oil cooler, Goodridge oil cooler lines, high flow air filter, KoolMat race tunnel heat shield, Kooks ceramic-coated headers and a CORSA® 100-percent stainless steel performance exhaust system.

Katech Performance has enhanced the C6 Z06 transmission with a high-performance clutch and an RPM Transmission Stage IV T56 upgrade featuring 300M output shafts, bronze fork pads and cryo-treated, micropolished internals. Stoptech stainless steel braided brake lines and AP Racing Super 600 brake fluid have been added to ensure the C6 Z06 stops as quickly as it starts.

Inside, a Caravaggio hand-stitched steering wheel with a flat bottom, emergency brake boot and shift knob and boot make known the vehicle’s elegant demeanor. Here the driver also will find a serialized Katech Performance manufacturer’s plaque.
