DeWitts radiator question
I'm considering moving to a DeWitts dual row radiator with both TOC and EOC. Has any one with a 6-speed car ever plumbed the EOC lines to also include the TOC inside the radiator? I suspect this will not lower the oil temp apprecibily, but may allow more WOT runs before the oil temp gets too high.
Those running the DeWitts, are you pleased with the performance?
My car is ProCharged.
Thanks

I just installed one in my 05 z51 M6 and pleased with it. average temp is down about 20-40 degrees over stock. not really sure what you mean about the lines. the z51 comes stock with TOC and EOC line to the radiator already

EDIT: Some owners are saying the radiator oil cooler on Z51 lasted through 2007.
And I was under the impression that in the base/Z51/F55 cars, only the automatics have a transmission cooler (which is in the radiator).
Our 2006 Z51 A6 and now 2009 Z51 A6, have the tranny cooler in the radiator and no engine oil cooler. They both have a power steering cooler near the pump.

My 2005 Z51 M6 definitely has both engine and tranny oil coolers in the radiator

I actually replaced the OEM unit with a DeWitt's all-aluminum radiator after the left tank developed a leak. I wasn't about to go through all that hassle to install _another_ radiator with plastic end tanks.

It definitely lasted through 2006. I have a March 2006 production manual-gearbox Z51 with the TOC and EOC integrated in the radiator end tanks.

Not really, though I'm not sure I'd expect to. During most of my driving, the temps are regulated by a couple of closed-loop control systems: the thermostat and the thermostatically-switched electric fan. On a road course, or on a truly sweltering day, the thermostat is wide open and the fan is roaring away - conditions where the DeWitt's probably makes a difference.
