[QUOTE="tt335ci03cobra, post: 16266620, member: 68944"] Yes but also indeterminable. You are getting to but never fully got to thermal loss being because as temperature rises, the metals and alloys become slightly tacky, much like a tire at 100° is slightly bendable just by hand. No, the metal is not sheering or breaking away, but yes, the metals and alloys are sticking to one another and starting to ever ever slightly melt together on surface contact. This is thermal loss. At 300°, it is so minimal that it doesn’t even equate to a 1% tranfer theft or thermal loss. The oils on the other hand have expanded their heat tolerances so general efficiency may be down more than 1%. What you are describing is what I brought up in greater detail earlier. Keep in mind, cars are NOT dyno’d super duper hot and on the brink of sheering an axle or diff. I’ve been to many dyno days, and temps don’t exceed 200° water, 240° trans etc, unless a car isn’t put together well. Factory cars easily handle dyno pulls and stay well below even the specified operating temp range. All of this is based on time spent with big machinery, that said, I’m also speculating. I don’t get what noise transfer would cause loss, vibration I get, but modern drive trains don’t vibrate if at all a thousandths. [/QUOTE]
