You're supposed to add an extra quart for that kind of use. If the engine gets starved of oil, it won't last a day, much less two years. If people are seriously into racing, two years is probably average.
If he blew the engine, then he either overreved it or starved the engine of oil and spun a bearing, etc. If you keep track of the oil level, pressure, and temp, the engine should last a long time.
But does an extra quart of oil will take some power from the engine since the crank is flooded with oil?
I read that one of the advantages of Dry Sump Lubrication systems is that since the Crank is not flooded with oil the engine can generate more power because it has less friction from the excessive oils in comparison with Wet Sump Lubrication........

That holds true but not at the high RPM's needed for racing. :cheers:

Theoretically, if you're on a track most of the oil is pressed up against the sides of the oil pan. The extra quart ensures the oil pickup is covered in high g situations.
You are right since the Z accelerates, brakes and corners so hard you are under constant high g forces that moves the oil from side to side continuously....
So if there is power loss from the excessive oil is in low g situations.....
So these means that the next Z definetly needs to have Dry Sump
Lubrication.... :yesnod:

Adding another quart of oil for racing does not flood the crank with oil. If you've seen the inside of the LS6 or the LS1 engine you will see that it has a windage tray between the crank and the liquid oil in the oil pan. This prohibits the oil from being aereated. The extra quart of oil helps to assure that the oil pump pickup will stay covered with oil during high G movements of the car. Keeping adequate oil pressure to all contact surfaces in the engine is paramount to long engine life.
I've been running an LS1 engine on the track for 4 years, and have had NO lubrication problems. The engine runs as strong today as it did 4 years ago. The chances are that your friend sucked some air into the oil system, and air doesn't lubricate very well.
The LS2’s new oil pan was developed to ensure oil delivery commensurate with Corvette’s high-performance capability. Extensive track testing has shown the new design to provide better oil control under the extreme demands of high-rpm/high g-force driving maneuvers. The elimination of the previous “gull wing” oil pan design also reduces the engine’s oil capacity from 6.5 quarts to 5.5 quarts with a dry filter.
Intresting but they don't explain how does it improves the lubrication to the engine...... :confused:
I believe that if the car was bought for racing and thats what it's been doing for the last two years,the guy probably was surprised it lasted as long as it did. Shucks, he was ready to change the engine shortly after he bought it if
he's really serious about road racing. I think two years is definately a testament to the engine's reliability. Don't you? :smash:

I would have to agree. Two years is amazing to me. How many other racing engines last this long? A good Nascar engine is torn down after "only" 500 miles.
