LS9 Engine Details

The LS9 Engine! V8 Supercharged Aluminum-Block Engine

Info courtesy of GM

The ZR1 (very limited availability) is powered by a 6.2 Liter aluminum-block V8 boosted by an Eaton® TVS™ (Twin Vortices Series) supercharger for a total power output of 638 hp at 6500 rpm and 604 lb.-ft. of torque at 3800 rpm. It is the most powerful motor ever to occupy the engine bay of a General Motors production car.

The supercharger features four lobes instead of the usual three for higher power and efficiency. It also features an intercooler to cool down the air/fuel charge for more power. In addition, nozzles squirt cooling oil into the underside of each piston.

The engine also features a dual-pressure fuel injection system for peak performance during multiple operating conditions.

Like the LS7 engine in the Z06, the LS9 features titanium connecting rods and exhaust valves as well as a dry-sump oil system with a larger capacity reservoir − now 10.5 quarts. The LS9 is hand-assembled at the GM Performance Build Center in Wixom, Mich.

Dry-Sump Oil System

The dry-sump oil systems on the Z06 LS7 and ZR1 LS9 engines prevent oil starvation on high-g corners or under heavy braking. The system uses an additional oil reservoir separate from the crankcase and pumps oil through the engine to ensure proper lubrication under high-performance situations. Oil capacity has been increased to 10.5 quarts for 2009
