Turbo compressor size

Hey guys

Quick question, is the turbo compressor size inducer or exducer size, or just a general mix of both.
I’m only asking because I’m trying to do some simulations of real life turbos, I’ve had a search around but couldn’t find an answer to this anywhere on the forums
Do you think trim ratios will be included in any future updates or are you happy with how it is now?

Thanks!
