So after reading the last part of this thread, one could conclude:
For a 90% street car revving to 7K RPM max, it really doesn’t matter how large your turbo(s) are if you have the proper converter. So really you should basically get the largest turbo(s) you can afford that will make the power you want. So for a twin set-up for example, you could get twin 76s or twin 78s (like Mihovetz has) and for a single, you could go with like a 101mm or 106mm--even though a single 78mm or 80mm will get you to 1000rwhp through an auto. So my point is, how do you size a turbo for an auto set-up if the proper converter will always make the car perfectly streetable and make it spool fast? It seems there must be a limit to the size before there would be some serious lag.
This surely doesn’t seem right to me but what do I know. I’m just a fellow hot rodder that is here to learn.
