This much change seems to evidence a much smaller turbine section than before.

It is not very conceivable that a lighter rotating mass or larger & improved compressor would be able to do that.

My fear is a smaller hot side will keep the compressor from realizing some of its potential.

If you do have a larger compressor and a smaller turbine, the wast gate circut can have to work harder and that can lead to boost creap in some cases. Just somthing to watch for.

I am far from an expert on turbo's. Just very interested.

Thx again.
