Mercedes AMG power

[Powerslide]

Is it me or has mercedes-amg pulled this one off with a extraordinary large compressor wheel? it this their trump card? image is of a 2014 power unit. Are turbo specification limited by the fia or free other than only allowing a single turbo?

Compressor sizes have been gone into at length.

Because of the compressor location, Mercedes have used (or have been able to use) a large diameter, thin, flat compressor housing. A typical automotive turbocharger uses a housing where the diffuser is "rolled up" reducing the OD and increasing the thickness.

Not really, its rather more involved than that. The compressor design drives the location requirenents and not the other way round. Compressor efficiency is a significant lap-time influence.

For reference purposes most centrifugal compressors used in aviation applications that I have seen have the large diameter but flat design characteristics as shown by the Mercedes compressor in that picture.
