All depends on how hard you want to push car.
The OEM oil cooler basically is a liquid to oil cooled unit. It uses engine coolant to run through the cooler, it's basically like a radiator. So I think the real problem is that the engine coolant is trying to cool not only the engine radiator but also the engine oil, via oil cooler. My plan is move to an air-to-oil, oil cooler. I've been following another guy on the Camaro forums and he's using dual air-to-oil coolers and his oil temps have come down a bit along with coolant temps coming down significantly do to the engine coolant no longer needing to cool the engine oil.

Of course not and even if I was, the ZL1 shuts the AC off at over a specific throttle %.

A manual fan switch might also help, but not if the stock radiator cannot keep up with that boosted heat.
A better than the stocker, vented/ducted hood could also help (IF available), and also add a little more front down force as well.
REALLY nice ride
, but this is EXACTLY why I like NA for road race type apps (a la 5th gen Z28), and YES, I have heard of all of the great boosted cars that can turn left and right and brake EXTREMELY well.
Yeah Ron Davis makes a radiator. I'm actually running the Ron Davis heat exchanger for the blower. As for the hood, the ZL1 comes with a vented hood for heat extraction and to aid in down force. I agree a N/A car is far better suited for road course events. Unfortunatley I really got into HPDE'ing AFTER I got the car
I don't disagree with you putting on an oil-air heat exchanger, but would like to point out that the oil-coolant heat exchanger provides for faster warmup of the oil, and the radiator was sized to provide good cooling even with the heat of the oil being dumped in it. (Heavy duty diesels have used oil-coolant heat exchangers since I don't know when, and they work fine.) With the air-oil cooler on it, just allow a little extra time for the oil to get to operating temperature before hammering it.
But it doesn't hurt to add margin, and rejecting the oil heat through another heat exchanger will help the radiator keep the engine coolant temperature under control. If you keep the fluid temperatures under control, the engine should last a long time.
Have you had any issues with the power steering?
