C7`s are not alone when it comes to heat soak issues. Hellcat`s have it, EcoBoost`s have it, Corvette`s have it and so do many of the imports. Many, if not most OE cars with SuperChargers or TurboChargers experience this problem if driven hard for any extended or repeated period of time/s. The computers do their job and pull timing so the damage isn`t permanent and the cars go slower and sometimes to Limp In mode.
There is no doubt that someone will say my boosted engine doesn`t have this problem. Smaller displacement boosted engines seem to suffer less and there are models that have particularly good ventilation that don`t show these issues or at least don`t show the issues because they aren`t run hard enough. There`s a reason cars like the Demon, Ford GT or Bugatti`s have multiple to many heat exchangers and air ducts on them. These cars produce serious heat. The heat problems have existed for a long time, prior to boosted engines it was vapor lock on naturally aspirated engines. Charged engines just show this problem big time.
I`ve been following a lot of discussion on the 3.5 Liter EcoBoost Ford`s. It`s almost a given that if you`re going to run them hard that an aftermarket larger CAC and piping be installed. DI engines add a whole other set of issues when associated with pressurizied engines. Changing to lower temperature thermostats, adding catch cans and a larger CAC/Intercooler are pretty much expected if you`re going to race these vehicles.
The only difference here is that due to GM`s marketing, Corvette owners EXPECTED to buy a car that could go from street to track (run hard) with no issues or upgrades required. It just ain`t so and probably a little naive. Are they entitled to refunds? I don`t know but have to think that most weren`t looking at the big picture when listening to the marketing hype. One thing I`ve learned is that race cars don`t come with warranties.
