Been battling the jointly rising coolant temps 262+ and Oil Temps 300+ on the first lap with a 2650.

I have conversed with a ton of folks with stock blower, aftermarket blower, and ported stocker. Seems the thing that everyone that is able to do laps in their car has done is a seperate oil cooler setup.

I put a call into C&R today, as noted they don't make a radiator for the ZL1 or ZLE. During the call they stated that they found greater performance with seperation of the oil cooling from the engine cooling. Their solution is to replace the side cooler that performs secondary HX functions, make that an oil cooler, and put a larger primary HX into the car. Details to come out soon ISH.

For now the Improved Racing with a SetRab hanging off the front of the car from say the front crash beam is going to be the way to make it happen.
