The LS Engine from GM: LS Swap Everything!

LS9 Engine

The LS9 engine, a pinnacle achievement within the LS family’s fourth generation, is an engineering marvel that represents the epitome of power and performance. Introduced in 2009 as the powerhouse behind the Chevrolet Corvette ZR1, the LS9 is the embodiment of supercharged excellence, combining cutting-edge technology with a relentless pursuit of horsepower.

A different look versus the traditional LS intake manifold center that you’re probably used too, but the LS9 also from the 4th gen of LS engines, picks up where the LS2 delivers and then some.

At its core, the LS9 features a 6.2-liter V8 engine equipped with an Eaton R2300 supercharger, setting the stage for awe-inspiring power delivery. The supercharger forces air into the engine, creating a higher air-to-fuel ratio and thus significantly increasing the power output. This results in the LS9 producing an astounding 638 horsepower and 604 lb-ft of torque in stock form.

The LS9’s engineering excellence goes beyond raw power. Its aluminum block and high-flow aluminum cylinder heads ensure durability and efficient heat dissipation under the extreme conditions the engine is capable of generating. The supercharger is integrated seamlessly into the design, providing substantial power gains while maintaining drivability and reliability.
