Inconnel Turbine Wheel?

[jdmspilner]

What are the benifits of having a inconnel turbine wheel? Can someone explain to me why it is a good thing?

Can handle more heat. Inconnel is basically a stainless steel with higher nickel content. That's a simple explanation.

The Holset turbos use Inconnel and have for a long time. I don't know about the rest.

Would the added heat help spool? (the turbo is a ITS)

 

[lambertvr4]

Using Inconnel for a turbine wheel is intended to provide a more durable and reliable turbo than stainless steel. It really doesn't have anything to do with power or spoolup.

Arent mitsubishi and garrett turbine wheels inconel?

So for the options are inconel or titanium alloy.

Inconel 718 is more durable to extreme heat, the titanium alloys used in the EVOVIII turbines they are having trouble with longterm! it spools quick but not lasting!
