Why? Happens every time you shut down the vehicle anyway. If you use good quality synthetic oils and the proper viscosity in the vehicle you really don't have to worry much about oil coking.

I'm just thinking that accelerating up to speed and immediately cutting the engine will stop oil flow and air flow of a turbo that has just seen the high EGT of acceleration. Maybe this mod would be a good excuse for a big GTB2056VL or other water-cooled turbo and an additional electric water pump.

I know this is a very old thread, but would squirting water on to the turbo housing provide any benefit for engine shutoff? Or is it primarily the shaft that transfers the heat.
