Has anyone had any experience with converting their 8qt dry sump to the newer 10½ qt dry sump? I am considering the change because at greater than 1.3 g's the bearings can become oil starved. And since I track the car using Hoosiers, I was advised that sooner is better than later.

I notice that the GM 10½ qt dry sump appears to have a different oil cooler compared the earlier Z's.

Was wondering if the older oil cooler must be swapped out in favor of the newer one when the oil tank reservoir is changed to the larger capacity reservoir?

Any comments would be helpful.

You can send it in to Lingenfelter to have it enlarged or bolt in the new larger tank. The 09 Z06 has the new style tank with the old style of cooler I believe. The 2010 or 2011 was the first year Z06 to get the oil pan mounted cooler like the ZR1.

I have the new style of factory tank for sale if you are interested. I took it apart cleaned it and reassembled it with new gaskets.

I just did the Lingenfelter tank and have had no issues. I've run mine on both Hoosiers and Pirelli slicks.

If you can find the new style OE tank user, that may be the least expensive. Getting it new is a lot more than the Lingenfelter tank.

Either oil cooler will work.

Thanks for the response guys.

I upgraded my 07Z dry sum tank to the 09Z tank. Only problem was that the temp sensor is in a slightly different location and it takes some "adjustments" to get it plugged in correctly. Easy installation.

if doing this upgrade, you may want to consider the aviaid baffle for the inside of the tank. It is supposed to improve de-aeration of the oil.

Thanks for the reply. By the way, why did you choose to go with the '09 oil reservoir instead of the Lingenfelter product? Cost w/Lingenfelter is substantially lower. Just curious

I have the extended warranty and I didn't want any grief in the event of a failure.

Very good point. I do as well. I think you made my decision for me.
Thanks!

Check with the local dealership. I did, and they told me that they would honor the powertrain warranty as long as I didn't reflash the PCM or get into the heads/cam. Headers, intake, injectors, CAI, oil system, etc were all ok as long as I didn't go smaller. They even covered suspension issues under warranty when I had a full Pfadt setup on the car.

Problem is if you blow the engine the dealer doesn't make the call. The GM Rep does. If you drop a valve the rep may not care which reservoir you used but if you spun the bearings they just make an issue out of it.
