Chevrolet makes the C7 Corvette Z06. That generates 650 horsepower and 650 lb-ft of torque. That output produces an enormous amount of heat. So much so that many people who take their Z06s to the track have ended up overheating them. Companies such as LG Motorsports and GSpeed are trying to cool the bad situation down, though. They’ve both posted their efforts on our sister site, CorvetteForum.com.GSpeed said, “Since we’re located at the Motorsports Ranch in Cresson, TX, we’ve got the ideal thermal testing environment literally in our backyard. For those of you not familiar, OEMs come here on a regular basis in the late summer to stress test cooling systems on track in the 100 + heat. Our goal for this car is to run a full HPDE session at Circuit of the Americas without overheating.”The company started by trying a DeWitt Gen1 radiator and an oil cooler. That enabled it to track a Z06 for an additional two laps over stock. GSpeed progressed to using a pre-production LG Motorsports kit “with the ‘cheek mounted’ heat exchangers for the supercharger.” It then added an auxiliary radiator in front of the main radiator. It put water temperature sensors at the engine inlet and outlet, and between the two radiators. It also monitored air temperatures in front of and between both radiators, and behind the main radiator. GSpeed determined the second radiator was hurting airflow through the main unit and preventing a useful change in air temperature across the primary radiator. According to the company, “What’s happening is the hot (235 ) coolant is hitting the cool (95 ) air coming in across the auxiliary radiator. When that happens, the air is heated up to about 180 , and the coolant is cooled to about 180 . The end result is zero heat transfer across the main radiator.”That didn’t slow GSpeed down. It’s still working at it.
