With a supercharged 6.2L LT4 V8 engine producing 650 horsepower and 650 pound-feet of torque, the Chevy Camaro ZL1 is already one of the most powerful sports coupes on sale today. However, there are always those enthusiasts who will demand more performance from their car, no matter how powerful it is from the factory, which is where the Michigan-based engine experts over at Katech step in.
Katech is a well-known engineering firm that built a name for itself by producing engines for motorsports applications – including the Small Block V8s that powered GM factory team Corvette Racing to multiple Le Mans victories and ALMS championships. Its upgrade packages for the Chevy Camaro ZL1 promise to give the supercharged sports coupe a reliable boost in power, with the Stage 5 kit being the most extreme offering available.
Katech’s Stage 5 kit for the Camaro ZL1 includes a Magnusson 2650R supercharger, Katech K-Force 3 camshaft, Katech CNC ported cylinder heads, Katech 103 mm throttle body, a Rotofab Big Gulp air intake, a Katech wet sump oiling system, Katech Spintron-validated valvetrain and a Griptech upper pulley, among more. These upgrades translate into a 280-horsepower gain over stock – transforming the 650 horsepower ZL1 into a 900+ horsepower beast. The upgrade kit also comes with a set of Katech slotted valve covers for a slight cosmetic upgrade as well.
The company recently released a video showing a customer’s Stage 5-equipped Chevy Camaro ZL1 undergoing some test and tune runs on the dyno ahead of delivery. The video allows us to hear how the above upgrades make the beastly 6.2L LT4 V8 engine sound and also includes some underhood shots of the heavily tuned engine.
