Ok, then explain to me how heat energy, without flow or expansion, will turn the turbo.

I do have the book; as well many other books. It makes mention of thermal energy and its contribution to enhanced turbine efficiency.

Page number??

Apart from the heat issue in the turbine side, the compressor side of the turbo does not suffer from heat soaking all that much.

So you’re saying that the compressor side gets too hot to touch just simply because it’s a compressor? Do you really think that a compressor making 7psi will generate that much heat.

That’s after the fact that the compressor side of the turbo puts heat into it. And that heat is primarily generated from the exhaust side of the turbo.

Added heat on the turbine wheel means added work on the turbine wheel. The more work put on the turbine, the more work performed by the compressor; period.

So if you have a car on a dyno and boosting, then put a torch onto the turbine housing, you will be making the turbine work more, therefore making the compressor side work more?

The torch on the undriven turbo is just plain out of left field.

The point is that heat, without flow, will not turn the turbo. PERIOD!!!
