What is the GM 6.2 Liter V8 Supercharged LSA Engine?

More than sheer performance, the LSA balances great power with exceptional refinement. Everything from the pistons to the aesthetic engine cover was carefully selected and tuned to deliver quiet performance. An advanced, sixth-generation Eaton supercharger with high-twist four-lobe rotors is a large contributor to the engine’s quiet high performance. It enables a broad power band with almost imperceptible operation. GM engineers created 370 different power simulations to optimize the LSA. It has been validated beyond 100,000 miles and has accumulated more than 6,400 hours of dynamometer testing. During testing, it was run more than 270 consecutive hours at wide-open throttle without a failure, and it completed actual and simulated 24-hour track tests.

  • Enhanced Cylinder Block: the 6.2L engine block used with the LSA is cast from 319-T7 aluminum and fitted with cast-iron cylinder liners. Compared to previous blocks, it has been strengthened 20 percent by optimizing the size of the bulkhead “windows” to take advantage of material thickness in the bulkhead. The enlarged bulkhead windows also improve bay-to-bay breathing by managing airflow inside the engine more efficiently, thereby decreasing pumping loss, or reducing resistance to the pistons’ downward movement. The engine block was developed with the latest math-based tools and data acquired in GM’s racing programs, and it provides an exceptionally light, rigid foundation for an impressively smooth cam-in-block engine. Its deep-skirt design helps maximize strength and minimize vibration, and its aluminum construction reduces weight approximately 100 pounds compared to a conventional cast-iron cylinder block.  

• Deck Plate Honing: a precision machining process reserved for high-performance engines, is used on the LSA cylinder block to maximize engine life, reduce friction between engine parts and increase horsepower. It is advantageous in applications where cylinder head pressures are greater than average – such as with a supercharged engine – to ensure cylinder sealing and prevent scuffing of the piston against the bore wall. In the LSA engine, this means improved bore life and ring sealing. True bores and better sealing are keys to optimizing power. 

• Pistons with Oil-Spray Cooling: The LSA’s pistons are aluminum-cast from a high-silicon alloy developed for its combination of strength and heat-management properties. Casting reduces noise-generating potential, compared to other high-performance piston materials, such as forged aluminum, and is specified when noise and vibration control is a priority. The hypereutectic pistons are also lighter than conventional steel, which translates to less reciprocating mass inside the engine. Less mass means greater efficiency, high-rpm capability and a feeling of immediate response as the engine builds rpm. 

 • Lightweight Rotating Assembly: within the LSA’s cylinder block spins a balanced, dropped-forged steel crankshaft with an eight-bolt flange to mount the flywheel. The eight-bolt pattern increases clamping strength compared to naturally aspirated 6.2L V-8s, which use a six-bolt crank flange. Forged powder-metal connecting rods link the crankshaft and pistons. They are forged under extreme pressure from alloy metals reduced to powder, rather the melted to liquid, for a balance of low mass and high strength. They reduce pressure on both the rod-end bearings and main bearings, compared to conventional rods, and allow the bearings to be optimally sized for the least amount of friction.  

 • Refined Low-Lift/Low-Overlap Camshaft: a refined camshaft helps balance the 6.2L LSA’s high output with smooth, tractable low-rpm performance. The torque-enhancing benefits of the supercharger allowed engineers to develop a “softer,” lower-lift camshaft for the LSA, compared to the typical high-rev, high-power exotic car engine. The result is smoother operation at idle and during low-speed driving. 

• High-Flow Rotocast Cylinder Heads: the LSA cylinder heads are manufactured with a unique rotocast method, which rotates the head mold as the molten alloy cools and essentially eliminates porosity, or microscopic pockets of air trapped in the casting. Rotocasting delivers a stronger part that helps maintain performance and structural integrity over the life of the engine. 

• Supercharger with Four-Lobe Rotors: state-of-the-art supercharging technology is the foundation of the LSA’s remarkable performance. The supercharger is an air pump driven by the engine’s crankshaft. It forces more air into the engine’s combustion chambers than the 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.
