Dry-sump oil systems are the apple of many a race-engineer's eye, and the technology has been making its way into passenger cars for some time now. Chevrolet's Corvette range is one of those adopters, having dry-sump oil systems in the ZR1, Z06 and, for 2010, the Grand Sport.

Though all three of those cars use similar small-block V-8 engines, they are all different: the ZR1 uses the supercharged 6.2-liter LS9, the Z06 uses a 7.0-liter LS7, and the Grand Sport uses a modified version of the 6.2-liter LS3. All three applications use the same dry-sump oil tank, however.

The main purpose of a dry-sump oil system is to allow an engine to pull higher g-forces without causing oil starvation issues than would be possible with a standard wet-sump oil system. In some applications, the lack of a tall oil pan on the bottom of the engine also allows it to be placed lower in the chassis, lowering the car's overall center of gravity and further improving performance.

To learn all about the Grand Sport's LS3 dry-sump application, watch the detailed video below.

  1. Great explaination of the system, however just for demo purposes, they couldn't clean up the botched up welds on the sump?
    For them to throw the notion that the engines are individually built (akin to AMG engines), is to create the idea that the engines are perceived to be of higher built quality, but they fail on the obvious lack of attention to details.

  2. well IGT that is a harsh criticism of the video and product, no need to be so negative unless you are one of very few AMG driving fine suit wearing million dollar house owning car aficionados in the world, I hope you can read my response even thought its not hand laid in gold leaf on your monitor.

  3. Its a simple observation. I enjoy what corvettes bring to the table, but Id never buy one is simply due to their finishing. Keep building up on its stats as a performance car doesn't negate its need to be a car you can live with. Many reviews address this point, for the same money from other car makers you can get more car, maybe not as much performance, but you can live with it at the end of the day. Put it simply if they want to charge me $80K for a car, they need to justify it in the details, not in the performance numbers.
