or more importantly the 2 different types of metals used to create the turbine and the housing expand at different rates hence the reason you should warm the car up in the begining. and also when turning off the engine, you generally let the temperature return to normalized operating temperature, hence the turbo timer to leave the engine running to allow the metals not to abnormally contract and cool down safely.
sounds suspiciously like you have no idea what youre talking about.

since turbo timers have everything to do with the oil getting hot and turning to sludge, and nothing to do with metal expanding, i dont see how anything you said means anyting.

my dad was test driving a cooper S, and the salesman told me that the turbo didnt need to be cooled down, yet had no answer when i asked him what was going to prevent the hot oil around the turbo turning to sludge.
