This is probably more suited for the tech forum. But it has occurred to me lately & most recently when one of my sons suffered a cracked cly.head some piston ring & head gasket fatigue as to what is going on with others here as well.That I read about from time to time. Some of the old guys that have been around probably understand this. But when you have an engine tuned with high boost on the ragged edge especially, every time you hit the throttle one needs to imagine a blow torch scenario attacking every moving part in that engine, especially the pieces just mentioned. When you put a car on a dyno or hot lap the **** out of it on the street enormous thermal stress's & elevated oil temps. are at play. Inter coolers,oil coolers & enhanced cooling systems certainty help but only to a point. I just don't think some realize these basic facts when out there going for joy rides.There is nothing I or anyone else can build that will stand up to these kinds of abuse. Now excuse me my wine glass needs another refill.
