Was wondering if anyone waits in park before turning their SHO off. People have told me to wait, people with older turbo cars. But I have also heard the F150 has a system so that you don't have to idle. I was told the purpose is to have the oil circulating while not under load to cool the coil because the tubos still spin for a second or two after the engine has been turned off. That its better to have cool oil running threw the turbos. I've been waitin ( have a smoke in park) then turn it off. Does not waiting have any effects on the turbos or is it a waste of time?

Yes, that is common with older turbo'd cars.  I believe the SHO has an automatic timer so you don't have to.

What I have read is that the cooling system is designed to allow coolant to "flow" into the turbo housings using the method of convection. This allows the turbo housing to cool when shut down after stopping to prevent the oil from coking in the bearings. As the hot coolant rises-cooler coolant is drawn in.
