OEM's use PD blowers for packaging reasons, that is it.
All PD blowers heat soak and yes they are water cooled and then after a hard run the water warms up and you have to wait for it to recover.
PD blowers are fun to drive if you have traction but I prefer a Centri in a RWD car where traction will be your limiting factor.
Centrifugal superchargers do not heat soak any more than your alternator does and is a bit disingenuous to compare something that hangs off the engine and has no direct heat transfer contact other than the bracket to a giant lump of metal that sits on top of the engine and has hot coolant running through it.
Meth gives you very consistent IAT's in a Centri. I'm spending a ton of money right now getting the PD blower in my S4 to stay cool, it is a giant heat sink and puts a ton of extra heat into the cooling system.
