I went from the oem Z06 cooler to the oil/water cooler that comes with the ZR1 etc because the eforce kit comes with it. This is still remote cooler but my point is that oil to air is better.
My oil temps went up 25 degrees on highway and then now they match the coolant temps when running hot in traffic. This effectively removed the additional cooling I was getting by having lower temp oil than coolant.
Separate oil cooler is the way to go especially on the undersized C6 radiator. Even 10% more core volume for engine coolant has to count for something.
If you have no overheating issues the new oem style water to oil cooler is a clean way to go but for max performance the air cooled type is better. IMO

I bought the dewitts with 3" cutdown and both eoc and toc built in... 2005 z51 also... the oil temps are definitely lower then the stock setup( highest seen now is like 220 vs stock 240 when getting after it), but I will probably eventually build my own separate oil cooler setup, but leave toc hooked up to radiator...

If you get a full sized dewitts radiator with eoc/toc, do you lose coolant cooling surface area....vs. a coolant radiator only? Basically....if you did a eoc/toc dewitts setup now.....and then eventually going to dedicated eoc/toc units and capping the coolers in radiator if needed?

I have a 6.8 liter, D1 in my C6. My experience has proven that a full size DeWitts and a separate EOC is the best solution. I've tried the DeWitts full size w/EOC and a shorty DeWitts w/EOC. Neither did the job.
Keep in mind that at normal operating temps, the oil circulating through a radiator oil cooler is actually heating the coolant.
So, here I sit with two DeWitt's radiators and they need a home.
The shorty w/EOC is practically brand new with maybe 100 miles. The full size w/EOC has around 5k miles and has some minor fin "scrapes".
Reasonable offers considered.
