There are no water to air intercoolers in UE version? (even in my dad's car the 1.2 TSI with 8V SOHC has a water to air intercooler with probably shortest piping on a turbo engine I have ever seen)
Back to the thread:
@skodakenner your title is suggesting a water-cooled turbine (VTGs mainly?).
As already mentioned... we can't really have all the tech there is in the big world
