LT6: The New Performance Benchmark
Part Two
A plaque mounted between the plenums identifies the engine builder. It's signed by the person who built the entire engine.
More good news: The Corvette Engine build experience, first available in 2011, (RPO PBC, Quantity: 16 (0.12%), $5,800.00) will be available on the Z06.
Is a modern Corvette without an Easter egg still a Corvette?
Maybe not as it seems to be the trend in recent years. For the Z06 LT6 engine, a rocket was embossed on the front of the LT6, meaning that it cannot be seen unless the engine is removed which is unfortunate. The backstory here is that the working moniker for the LT6 during its development was Gemini, owing to its two camshafts, two throttle bodies and two fuel pumps. Gemini was also the name of the two astronaut space capsule that preceded the Apollo three astronaut capsule.
LT6 engine oil filter. During the development of the LT6, the vibrations - a consequence of the flat plane crankshaft - were so bad that a conventional oil filter unscrewed itself on a test stand. A bolted on cartridge filter was the solution.
The oil system is a dry sump, similar to the C8 Stingray. The lower portion of the block has four bays so each crank journal has a sealed bay (reducing windage) with oil scavenged from each bay and the two cylinder heads. Each piston has an oil squirter for cooling.
The LT6 in the C8 Z06 was not the first time that double overhead camshafts and four valves per cylinder was available in a Corvette. The LT5 engine in the 1990 Corvette ZR-1 also featured the same configuration and was rated at 375 horsepower; subsequent updates enabled an output of 405 horsepower. Unlike the C8 LT6, the C4 LT5 was designed by Group Lotus and built by Mercury Marine in Stillwater OK.
Below is the 1990 Corvette ZR-1. In addition to the double overhead cams and four valves engine configuration, like the C8 Z06 it also featured a wider rear body. Unfortunately it was not all that visually distinctive from the standard Corvettes at the time which lead to poor sales. It was last sold as a 1995 model.
