But - isn't all QSC8.3 engine's turbochargers water jacketed on the turbine housing?Dual purpose. Keep heat in the turbine housing to keep gas velocity up through the turbine and also to stop heating up everything else around it.
On a QSC 540 probably good idea to remove during inspection to see if the waste gate shaft seal is leaking as evidenced by black soot around the shaft. Not a cheap repair.
I ceramic coated the turbine housing and used a turbo blanket on my 400 rwhp 2 litre 4 cylinder. Stops the paint on the hood blistering too, but still didn't save the nearby ABS system.
On a turbo race car, the turbine housing can glow cherry red.
I believe the QSM11 like mine below are the only Cummins dry turbos for marine use.
