Hennessey Performance Engineering are masters at tuning up General Motors’ LS engines. Their twin-turbocharged LSX-based 7.0-liter engine is capable of producing up to 1000 horsepower at the rear wheels, a feat we saw first hand during a dyno run of their VR1200 Cadillac CTS-V Sport Wagon. The best part about this engine is it can be dropped into more than a couple GM products, including the already extremely fast Camaro ZL1.
This Camaro ZL1, which HPE built for a customer, isn’t producing nearly as much power as the insane aforementioned CTS-V wagon was, but it’s still throwing a respectable 876 horsepower at those wide rear tires. The parts list for this build is too long to list (view the full thing here), but some crucial components include forged steel rods and forged aluminum pistons, a custom HPE camshaft, high-flow cylinder heads, an air-to-air intercooler and of course, a pair of big ball bearing turbochargers.
The result of all this American-muscle goodness is a 10-second quarter mile at 135 mph, a loud exhaust note and lots and lots of tire smoke. Check it out in the video below.
