As the power behind the 2019 Corvette ZR1, the new, supercharged 6.2L LT5 represents the pinnacle of Chevrolet’s performance: It’s the most powerful engine ever offered in a Chevy production vehicle. The Chevrolet Performance LT5 crate engine delivers 755 horsepower and 715 lb.-ft. of torque. It builds on the successful supercharging legacy of the LS9 and LT4 engines, with advanced technologies such as camshaft phasing and direct injection.

An all-new, 2.65-liter supercharger (64 percent larger than the LT4’s supercharger) pumps out more 13.9psi of peak boost and blows into a robust charge-cooling system with about twice the capacity of the LT4’s system. It’s supported by a unique dual-fuel system that features eight port-style injectors, which complement the engine’s standard direct injection system. That’s a grand total of 16 injectors, with the auxiliary port injectors supporting the direct-injection system under heavier fuel loads such as wide-open throttle.

The LT5 also features the largest throttle body ever on an LS or LT engine, an electronically controlled bypass for the supercharger, specific heavy-duty main bearings and more. The bottom line is there’s never been a more powerful production-based crate engine from Chevrolet Performance—and it’s ready for your ride!
