One of the key features of the supercar Sedan the Cadillac CTS-V is the engine. Codename LSA, it is a supercharged, intercooled 6.2L V8 engine making 556 hp, 551 lb-ft of torque. It is unique to the Cadillac CTS-V. It is a lot like a Supercharged LS2 engine.
Gen VI Supercharger with Twin Four-Lobe Rotors
A state-of-the-art supercharger is key to the 6.2L LSA’s remarkable performance. This Gen IV small-block V-8 is equipped with Eaton’s Twin Vortices Series (TVS) supercharging technology, which represents the sixth generation of joint Eaton/GM supercharger development. The LSA supercharger displaces 1.9 liters and generates maximum boost pressure of 9.0 pounds per square inch (0.62 bar).
A supercharger is essentially an air pump driven by the engine’s crankshaft. It forces more air into the engine’s combustion chambers than that engine could otherwise draw on its own. The increased volume of oxygen allows the engine to efficiently process more fuel, and thus generate more power.
The TVS takes supercharging technology to new levels of refinement and efficiency. Each of its two rotors has four distinct lobes, or spiral-shaped vanes that intermesh precisely with those on the other rotor as they spin at high speed. Efficiency gains with the four-lobe rotors are substantial, compared to comparably sized, previous-generation superchargers: Approximately 20 percent more airflow, with an improvement in thermal efficiency up to 15 percent. Moreover, parasitic power loss-the amount of power the engine uses to operate the supercharger-is reduced 35 percent. That improves both the supercharger’s response time and the engine’s overall efficiency.
With the TVS supercharger, the 6.2L LSA delivers nearly 1.5 horsepower per cubic inch of displacement and specific torque that’s at least 18 percent higher than any of its primary competitors. Yet impressive output figures tell only part of the story. The supercharger’s large displacement expands its effective range, building power more quickly at low rpm. Its four-lobe rotors spin at over 15,000 rpm, or about two and a half times the engine’s rotation speed, to sustain its benefits at high engine speeds, when many superchargers lose their effectiveness.
Redline Motorsports offers several performance packages for the 2009-2013 CTS-V to bring the current performance to even higher levels;
