Consider slipping the clutch for a whole second at idle speed. The crankshaft will have made about twelve revolutions in that time.

Now do it for a whole second at 3000 RPM. That's about fifty revolutions; over four times as many revolutions as those at idle.

So, if you slip the clutch for a quarter second at 3000 RPM, it's about as much thermal energy as slipping it at idle for a full second.

This makes sense to me (an accountant who wishes he spent more time studying physics). My only question is, if you're "dumping" the clutch rather than giving it a very quick slip, is the "shock" doing more damage to the clutch than the heat at that point? I would think it saves heat since there's less time slipping but wouldn't that instant jump in torque "shock" something in the system to cause extra wear than a light slip? Just genuinely interested in knowing since I too like to kick it out on the occasional U-turn (FRS drivers, am I right lol).
