I must comment on this
I must comment on this statement - "Part of the ZR1’s ability to withstand these extreme temperatures is the addition of four extra heat exchanges for the engine, along with a front fascia that directs far more cool air into the engine bay and the cooling system. As a result, the Corvette ZR1 is able to run for hours on end without running into cooling issues, helping to make it one of the greatest performance cars on sale today."
That statement is a joke right? The 2019 ZR1 manual transmission has a serious flaw in the cooling set up of the trans oil. The manual does NOT have a fan at the inter cooler located behind the left quarter panel. The vents on top of the quarter panel force air across the inter cooler, not through it! The FACT is that the trans oil temps rise every single lap on the track and the trans oil overheats inside 20 minutes even at 70 degree ambient temps. FACT! The manual transmission ZR1 cannot handle (2) 15 minute sessions on the track with a 15 minute break, even when an external fan is used to blow through the rear vent to cool the trans oil between sessions. All FACTS. I have all the data and GM knows all about it.
