Curious how a turbo is made?
Random find on youtube for those who might be curious:

Man..that's old school.
 Many impellers are done on 5 axis CNC machines now.. Impeller machining on five axis Starrag machiningcenter - YouTube BTW...that turbo in the video was the first single turbo I have on my Supra. Turbonetic T-66.

I was blown away with how manual the build is. I'd have thought that it was less "file and fit." But then turbos have been around for decades - before modern machining techniques. Fascinating. Thanks for sharing.

The sad, bad news is that a forced induction engine must be derated in off-boost mode.
The F150 V6 EcoBoost engine, were it not for having to accomodate boost mode, could have a CR of 12:1, maybe even 14:1. That results in relatively poor FE 98% of the time. |

Have you seen the Saab tech of variable compression engines with turbochargers? Old news/tech to the problem you describe.

Looks like Peugot or another outfit has taken it a bit further in recent times:
